Oracle on VMware

0

Hello,

 

I began testing Oracle (11g) on VMware (ESXi 5.0 Update 1) and comparing performance with a physical server.

Virtual machine is configured per VMware best practise for Oracle (paravirtual SCSI controllers, disks separation).

However physical server outperform a VM in transactions per second and response time.

Use the same storage array.

 

I will apreciate any advices/tips/recommendations from users who have experience with Oracle on VMWare.

 

Thank you in advance.

Database performance problem

0
0

We're running vcenter 5.1.0b with an Oracle 11g database.

 

We've had various performance problems such as slow search results, slow vcenter service startup, etc.  So I started to look at the database.  It turns out it has  854 tables!  Lots of VPX_HIST_STATX_XX tables.  And some of the various tables I checked like vpx_event_arg and they have over 10 million entries.

 

Looking at Administration | Database Retention Policy, I have 120 days of tasks and 61 days of events stored.  I suppose I could decrease that, but still something is obviously wrong.

 

Are there some performance things I could ask our DBAs to do manually?  For example some tables I could truncate or drop?

Hardware Optimization for my VMWARE

Hi,

 

I'm currently running a very resource consuming Oracle product on my vmware. Luckily, I have a very geared PC for the job. However, I require the wisdom of seasoned VMware users in the following

 

This is my current processor:

http://ark.intel.com/products/68316/Intel-Core-i5-3470-Processor-6M-Cache-up-to-3_60-GHz

 

Can someone kindly direct me as to what numbers I should be punching in terms of cores? The processor has 4 physical cores and 4 logical cores from what I understood. I tried punching in 4*4 in the settings (as a lucky guess). Didn't work out to my favor.

 

Thanks in advance!

Oracle RAC on vSphere4.1 - Performance Problem

0
0

Dear Mates,

 

We are seeing performance issues for the Oracle RAC VM's. Oracle Support say that queries are waiting for IO. Below is the environment.

 

2 node (VM) Oracle RAC setup.

1 VM in each ESXi server.

No other VM's sharing the physical server as of now but planned for other DB VM's.

Guest OS is RHEL 5.5

CPU and Memory utilization is less than 25% utilized, each VM has got 16GB RAM and 4vCPU's.

Each VM has got 10 RAW LUN's apart from OS in a datastore.

 

ESXi - 4.1 Update 2

Storage - HP EVA

Physical Server - HP Blade BL 460c G7

San connectivity VC Flex - 4*8 GB FC link with speed set as 4GB to match storage controller speed.

 

Attached are the performance report from vCenter server for respective VM's.

 

Do you see any abnormalities in values from the report, any help on this case is highly appreciated.

Enable hyperthreading for virtualized Oracle 11gR2 database (OEL57)?

0
0

We are virtualizing our Oracle 11gR2 databases (running on OEL57 64-bit) on Vmware 5.1.   I've read information at various locations that hyperthreading is not recommended for Oracle 11g database.  One example is here, however, I seen many more:

 

http://bryangrenn.blogspot.com/2011/08/hyperthreading.html

 

My issue is that Vmware themselves recommend enabling hyperthreading for virtalized Oracle databases in their Oracle Databases on VMwareBest Practices Guide.

 

Does anyone have any practical expierence with this issue that can be shared?  What are the advantages and disadvantages of enabling hyperthreading for our virutalized Oracle 11gR2 on OEL57 64-bit virtual machines


Thanks, Fred


Enterprise Manager Plugin for Oracle on VMware License Optimization

0
0

Is confusion, or lack of knowledge around Oracle licensing policies and fees on VMware preventing your enterprise from leveraging the technical and business benefits of Oracle on VMware to the fullest?

 

Blue Medora is seeking interested Beta participants to help us validate the features and functionality of a new Oracle Enterprise Manager (Oracle EM) Plugin, the Blue Medora Oracle Enterprise Manager (12c) Plugin for Oracle on VMware License Optimization.

The plugin provides an Oracle-based solution to the problem of managing Oracle workloads on VMware mixed Cluster environments where virtual machine mobility dramatically increases the risk of Oracle license over deployment and overspending.

 

The primary functionality provided by the plugin includes:

  • Reduce the risk of over deploying Oracle licenses within VMware Clusters
  • Mapping of virtualized Oracle workloads to the physical VMware ESX hosts
  • Detection, alerting, and remediation recommendations for vMotion and DRS Host Affinity related configuration issues
  • Recommendations for improved license optimization of VMware virtualized Oracle workloads

 

if you are interested in seeing more detailed information about the EM12c Plugin for Oracle on VMware License Optimization, and/or you would like to participate in our beta program for this release, please view the page and beta request form by clicking this link:

 

http://www.bluemedora.com/em12c-plugin-oracle-vmware-licensing-optimization-0

We greatly appreciate your input on this matter, so even if you do not want to be a beta participant, please consider sharing your thoughts on whether this set of capabilities would provide value to you and your enterprise.  We are always interested in what customers think; especially when it comes to extending the reach of Enterprise Manager!

Storage vMotion for Oracle RAC VMs

0
0

We are starting to virtualize Oracle RAC at our company.  Initially we followed the Oracle Databases on VMware RAC Deployment guide, which specifies using a bus sharing setting of "none" for most of the SCSI adaptors.  The same guide recommended using the "physical" bus sharing policy for SCSI adaptor related to the CRS and Voting disks.  We eventually ignored this and set the CRS and Voting disk SCSI adaptor settings to "none" like the other disks, probably because we wanted to facilitate vmotion, which cannot be done with the physical setting per KB 1003797.  While provisioning a new pair of RAC VMs, I noticed that storage vmotioning the "primary" VM where I had initially provisioned the shared disk left a copy of the shared disks behind on the old datastore, presumably because the second VM still refers to that location when looking at the shared disk - thus the 2 VMs no longer shared common disks.  How can I allow vmotion and storage vmotion for RAC VMs while preventing storage vmotions from "breaking" the shared disks?  Is there a "safe" way to storage vmotion these VMs?

Oracle 9i in VMware SCSI conflict errors

0
0

We have a copy of our production oracle cluster environment (three node) running in our VMware cluster.   We use this for backup purposes.   We run into this weird error once in a while:

 

Servername kernel: I/O error: dev 08:21, sector 45

Servername kernel:scsi1 (0,0,0) : RESERVATION CONFLICT

Servername kernel: I/O error: SCSI disk error : host 1 channel 0 id 0 lun 0 return code = 18

 

Then sometimes we get:

 

Servername kernel: ocfs_rw_direct : brw_kiovec() -5

Servername kernel: I/O error: need to fail out

 

THis causes the OCMSTART service to crash - taking down all the databases with it.

 

There doesn't seem to be a pattern at all - it worked just fine for weeks and then this happened twice this week.  I looked in this form and found this:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1034165

 

We do not have that turned on currently does anyone have any experience with that?  I have seen where people suggest that you move both database servers to the same host to help with the heart beat, also seen were one person suggested changing the disks to "independent" mode.

 

Before I start taking shots in the dark I was hoping someone might have an idea which direction to start.

 

Thanks in advance for any ideas.

Migrate Oracle RAC to Vmware

0
0

Hi;

 

Am wondering if anyone has ever tried migrating a present RAC environment (2 node cluster using ASM accessing a SAN for the data and flash). I know I can convert the physicals but all documentation I have found on disk sharing points to creating the disks and doing the multi-writer option. This is not possible when the added disk is using a Raw Device Mapping which is my only option when presenting the LUNS to the host server. This is an ora10g and ESXi 5.1.

 

Thanks

Hi Everyone,

We are running Oracle EBS on Physical machine having specs as follows:

 

DB

X2 Quad Core Xeon 2.4 GHz

32 GB RAM

x2 146GB SAS Drive with RAID-1 for OS

SAN HDD x10 450GB SAS 15K i.e. 4.0TB but RAID-5 implemented (2.3TB allotted to DB)

x4 NIC but 1 NIC used 10/100/1000


Apps

X2 Quad Core Xeon 2.4 GHz

32 GB RAM

x2 146GB SAS Drive with RAID-1 for OS

SAN HDD x10 450GB SAS 15K i.e. 4.0TB but RAID-5 implemented (500GB allotted to Apps)

x4 NIC but 1 NIC used 10/100/1000

 

We are facing serious issues when migrated Oracle EBS on vmware infrastructure.

Issue are related to high I/Os and high CPU usage hence performance of the application gets down badly whereas same application on physical machine working fine. We would also like to share physical machine is with lesser specification.


Following are specs of Oracle & VM Ware machine;

Oracle EBS is with 11g v1.1.07 Database and R12 v12.1.3 Apps

OS for above applications is RED HAT Enterprise Linux 5.5 64bit

ESXi version 5.5.0 build 1331820


Hope to have a positive reply.


Whose running Oracle on VMware

0

Hi Folks,

 

I keen on finding out the names of some large UK corporates have taken the plunge and virtuliased Oracle on VMware for production workloads. Although the company I work for has already started virtualising Dev/Test environments on VMware it has not yet opted to do the same for Production/Pre-Production. The reluctance is based around the support policy issues by Oracle - i.e supported vs. certified.

 

Anyway, I am putting forward a proposal to use VMware for production workloads and if I can name a few large corporates that already do this (especially in the Finanacial Sector) then I think it will help with the proposal. So if you either work for a large corporate or know of a large corporate that uses Oracle on VMware in production, and are happy to share the name, then it will be greatly received.

Oracle ASM or not?

0
0

Hi all!

 

I just read VMware's document titled "Oracle Database on VMware Best Practices Guide"... This is a very good document but I am wondering why it only adresses database setup using Oracle ASM.

 

I understand that for best throughput, one would be better to use ASM...

(I also understant that raw device mapping is the best configuration for performance - BUT I definitely would not recommend using RDM for the management complexity it adds..).

 

It does NOT seems simple to implement ASM here because of responsabilities (sysadmins vs dba).

 

So my question are:

 

1- Does anybody *NOT* using ASM for their Oracle Database on VMware with success?

What I mean by that is, no ASM instance, datafiles on VMFS file system...

 

2- Does anybody actually measured the difference in performance (between using ASM and NOT using ASM)?

 

3- I know it is adviced as a best practices (for best throughput) to separate online redo logs and data files - but is realy that bad NOT to do it?

Otherwise said, how detrimental is it to merge logs with datafiles.

 

Any thoughts/references are welcome...

If you are not scaling Oracle Middleware like this, then you’re doing it wrong

 

We have all built an Oracle Middleware box from scratch once. But, if you ever build an Oracle Middleware box from scratch twice, you’re doing it wrong! (click to tweet). Okay, maybe that is a little extreme. Surely there are some business requirements that justify building multiple Middleware deployments from scratch, but you should certainly do everything in your power to avoid it. Here’s how you should be implementing Oracle Middleware with today’s tools. (If you don’t feel like reading, jump to the end to see how Blue Medora makes your life a whole lot easier).

Oracle Middleware is designed from the ground up to be both vertically and horizontally scalable. Unfortunately, most implementations of Oracle Middleware do not effectively leverage these capabilities and many admins focus only on scaling vertically. To maximize your Oracle Middleware investment, you must have an appropriate strategy to horizontally scale within your private/public crowd.

Monitoring WebLogic J2EE on VMware with VMware vCenter Operations

 

The Blue Medora vC Ops Management Pack for Oracle OEM was updated in early May (2014) to include enhanced support for Oracle WebLogic J2EE integration. All of the Oracle EM target types for WebLogic related components including WebLogic Server, J2EE Application Deployments, Oracle HTTP Server, as well as WebLogic Cluster are now available to be ingested into VMware vC Ops Enterprise Edition.

 

 

With the data available within these new vC Ops 'Resource Kinds', you have the ability to create WebLogic on VMware relationship views, WebLogic on VMware mashup dashboards, as well as leverage vC Ops anomaly detection and predictive analytics on your WebLogic J2EE landscape. Below are a number of example dashboards that were easily created using the WebLogic data available within the Management Pack.

 

The first dashboard, the WebLogic on VMware Relationship View -- helps you visualize your WebLogic environment running on VMware all the way down to the VMware VM, ESX, and even Datastore level.   This can useful for diagnosing critical J2EE applications running within the vSphere environment -- allowing you to quickly discern whether a problem exists in the Oracle WebLogic layer or one of the VMware virtualization layers.

Navigating Up and Down the ‘Oracle on VMware’ stack using Oracle EM12c

 

This week Blue Medora released the latest version of the Oracle Enterprise Manager Cloud Control (EM12c) Plugin for VMware.

Among other things this release adds is a key feature that our customers have been increasingly requesting asking us for over the past year – the ability to begin the process of troubleshooting / diagnosing 'Oracle on VMware' integrated stack issues starting from the Oracle Database target main screen for a particular Oracle database instance that is virtualized on VMware, and from that page logically navigate to any or all of the related VMware layers including Virtual Machine, ESX Hypervisor, Cluster, or Datastore.

Use Case #1 - Navigating from a VMware virtual machine to a related Oracle Database

 

Since the first release of the VMware plugin has supported navigation in the other direction – navigating from the VMware virtual machine target home page to a related Oracle database instance running on the virtual machine.  This existing capability is demonstrated in the screenshot below:

Oracle ASM disk setup

0
0

I think I may need some help getting the storage for my ASM right. I changed companies recently and the new place is a Windows house so the Oracle databases are all on 2008 R2 machines. I have run Oracle RAC on both physical and virtual before, but only in Linux/Unix environments (which so far I still prefer) so I'm still learning some of the ins and outs. This company is also looking at moving to RAC, so ASM is in the mix. To begin my testing, I have set up an ASM instance for a single host which will eventually become a development hub holding several databases. However, even before I've set up any databases, the host is locking up. I suspect it has something to do with the disk configuration in that while the lock ups have occurred while the vm is idling, several lock-ups have happened when I try to drop a disk from within ASM. I followed the documentation that Oracle provided for Windows platforms, but this documentation of course does not offer insight into storage virtualization.

 

Here is my configuration:

VMware: vSphere 5.5

OS: Windows 2008 R2 Standard

Memory: 12G

Storage (LSI SCSI): OS: 60G; ASM: 20G, 5G, 5G

Oracle Grid: 11.2.0.4 (plus January 2014 CPU)

Oracle Database: 11.2.0.4 (plus January 2014 CPU)

 

Other details (maybe important, maybe not):

1) I have a large pages enabled

2) Disks are thin-provisioned. As a side-note, I've always thick-provisioned my ASM disks, but our Sr. IT admin has made a policy that all disks are to be thin-provisioned for efficiency. I'm not sure if this could cause an issue.

3) I am working on having the 3 ASM disks (20G, 5G, 5G) set up on different Paravirtualized SCSI controllers (another policy from the IT admin - LSI SCSI by default) as they will be used for DB, LOG, and FRA respectively.

4) The host also has an OEM 12c Agent installed and running.

 

I'm new to the Windows platform when it comes to Oracle (I've administered plenty of SQL Server DBs), but the lockups don't appear to be generating any kind of data to any logs.

multi-writer flag on Physical RDMs?

0

Hi there.

 

I've seen a lot talking about VMDKs and Virtual RDMs being shared between RAC nodes with "multi-writer" flag.

I also found out that this is working out with Physical RDMs, but i didn't see any statements on that. Only, as by best practices using Physical RDMs with the "Shared" option on the SCSI Controller.

 

Can anybody say if it's also supported to use "multi-writer" on Physical RDMs?

Dear Friends,

 

We have a 4 node Oracle RAC 11g R2 in vSphere 4. (I understand this being an Outdated version, we are working on upgrading it).

Meanwhile we are also addressing performance problem by making some tweaks but not much helpful.

Now the question been raised for a vSphere storage Multipath Policy change over from Fixed to Round Robin, but am worried about RAC stability post this change because of Voting Disks, your guidance in this case is much appreciated.

 

We are using HP EVA storage which is ALUA aware.

[Blog] Using VMware vROPs to monitor Oracle Database and WebLogic. Management Pack for Oracle EM, Hyperic Plugins, or Both?

This blog post provides a suggested methodology for helping users of VMware vROps/vCOps decide which of the existing solutions, the vROps Management Pack for Oracle EM and the VMware vROps Hyperic Plugins for Oracle, should be used to monitor their Oracle workloads.

 

It’s been a nearly a year since VMware transferred the vCOps Adapter for Oracle Enterprise Manager (OEM) to Blue Medora and since that transfer Blue Medora has released a number of major updates as well as rebranded it the Blue Medora vROps Management Pack for Oracle EM. Over that same period of time VMware has continued to evolve their Oracle-focused (Oracle Database and WebLogic J2EE) Hyperic agent-based plugins culminating most recently with a October 2014 update to the Oracle Database plugin that provides support for Oracle Database 12c.

New Oracle Licensing due to vCenter 5.1 changes?

0

There is a weird blog-entry at http://www.doag.org/home/aktuelle-news/article/oracle-aendert-lizenzierung-von-oracle-produkten-unter-vmware-vsphere-ab-version-51.html

 

DOAG is the German Oracle User Group

 

 

Oracle ändert Lizenzierung von Oracle-Produkten unter VMware vSphere ab Version 5.1

Oracle hat es in seinen Lizenzbestimmungen nirgendwo festgehalten, trotzdem gelten für die Lizenzierung von Oracle-Produkten unter VMware vSphere neue Regelungen: Nach Informationen der Oracle-Partner ist ab der Version 5.1 der Virtualisierungssoftware nicht wie bisher das Cluster zu lizenzieren, sondern das gesamte vCenter, in dem Oracle-Software installiert sind bzw. laufen.

Als Grund für diese Änderung nennt Oracle die neuen Fähigkeiten der Virtualisierungslösung ab Version 5.1: Virtuelle Maschinen können zur Laufzeit über die Cluster-Grenzen hinweg innerhalb eines vCenter verschoben werden.

Diese Regelung wurde auf Nachfrage der DOAG seitens der Oracle-Ansprechpartner bestätigt. Deswegen empfiehlt die DOAG, ein vCenter für Oracle-Produkte vorzusehen und 1-n vCenter für weitere Produkte zu nutzen.

Michael Paege, stellv. Vorstandsvorsitzender der DOAG und Leiter des Competence Center Lizenzierung, kritisiert diese Änderung der Lizenzbestimmungen und fordert weiterhin einheitliche Lizenzierungsregeln für alle Virtualisierungstechnologien. 

Diese Frage der Oracle-Lizenzierung unter VMware wird der Lizenz-Spezialist in seinem Vortrag auf der DOAG 2014 Konferenz + Ausstellung behandeln.

 

 

 

Ill try to tanslate this (i`m no native english speaker - so no guarantee for proper translation):

 

Oracle is changing licensing from oracle products under vSphere 5.1+

 

Oracle does not have it in detail in their licence clauses, tough for the licensing of oracle products under vmware vsphere there are new rules:  based on informations from the oracle partners, since version vmware 5.1 oracle does not only need to be licensed within the cluster but within the whole vcenter, in which oracle software is being installed or running.

 

oracle tells, the reason for this are the new features of vSphere 5.1:  virtual machines can be moved at runtime across cluster boundaries.

 

This rule was was asked by DOAG and was aknowledged by the oracle contact persons.   DOAG now recommends, one vcenter for oracle products and 1-n vcenter for further products.

 

Michael Page, assistant chairman of DOAG and leader of competence center licensing is critizising this change in the license regulations and demands uniform licensing rules for all virtualization technologies.

This question regarding oracle licensing under vmware will be discussed by the license specialist in his talk at "DOAG 2014 conference + exhibition".

Oracle DB Support on VMWare Environment

0

VMware claims that it will Take Total ownership of Oracle DB on VMware ESXi, and they would align their own DBA to help resolving any issue related with DB. Oracle will only support for known issues or they will ask to reproduce the similar environment on native OS.

 

I am confused about its licensing part. Can any one clarify this?

 

What is support and subscription of Oracle on VMware environment. Do we have to buy a separate license for Oracle on VMware or the same physical license for oracle for x86 machine will work? What if we have oracle license on physical machine - can we get VMware DBA support for oracle related issues?

What will be the cost of the license?

What will be the SLA of support of there is any issue?

 

 

I appreciate your response. Many Thanks.

Oracle ERP migration to VM

Hi All,

 

Greetings. Hope everyone is doing great.

 

Just wanted to get some insights on the migration of an ERP from physical server to virtual machine.

 

We are going to retain the same host name and ip for the new virtual machine.  So i need some help and suggestions on the cut over from physical to virtual machines.

 

Since DB and ERP are in filesystem,  i see it is just copying of files from one server to other server.  Is there a way we can copy the files faster?

 

Is there any other way this migration can be done with less down time?  Since both machines will be with same ip and hostname how the transfer can be achieved?

Oracle on vmware with EMC recoverpoint and SRM

Hi,

 

I will setup a new Oracle environment on VMWare and want to protect these Oracle vm's with EMC Recoverpoint.

We also use SRM. The Oracle vm's will be stand-alone vm's, no RAC and running Oracle Linux as OS. So I will use VMDK's.

Is there anyone using Oracle with Recoverpoint and SRM ? I am looking for best practices or whitepapers about this topic before I start

the implementation. There is an oracle on VMWare guide and Oracle RAC guides on VMWare but I can't find much info about Oracle on VMWare with Recoverpoint.

Multi-Writer Flag does not persist in Oracle RAC VM configuration parameter on VSAN 6.0 datastore

0
0

I am visualizing ORACLE RAC on vSphere 6.0 VSAN datastore using this following this article VMware KB: Using Oracle RAC on vSphere 6.x VSAN Datastore .

 

In every ORACLE RAC VM, the SCSi controller type is VMware Paravirtual and SCSI bus sharing is Physical in which shared disks are connected.
When I am trying to add multi-writer flag in Edit virtual machine settings> VM Options > Advanced> Edit Configuration, the flag does not persist when I view the same configuration parameter list. I have tried both in vsphere Client and Web client, even tried with vi editor and echo command to add the parameter manually in vmx file in the host in which the vm is registered.
But one strange thing happens - if i write the syntax wrong (e.g an extra colon or double quotation is added) then it persist.

Can anyone help pls.

Oracle licensing in a Vmware Cluster

0
0

My question is related with Oracle licensing in a Vmware Cluster.

 

We have two VMware cluster in our datacenter:  the first one (8 hosts – 16 sockets) is for not Oracle VM and the second (2 host – 3 sockets) only for Oracle VM. Both are connected to the same IBM V7000 with zoning and LUN masking that guarantees isolation.

 

In the Oracle cluster, DRS and HA are deactivated and VMotion logs are monitored for license compliance.

 

In this isolated environment, Oracle pretend to license every socket to any host connected to the V7000, regardless of the cluster that are connected the host.

 

Do you know how similar implementations with Oracle have been resolved (in terms of licensing)?

 

Thanks in advance!

I've opened a support call with HP/VMware on this issue and while I'm waiting on their response, I thought I'd try the community.  We've recently started virtualizing some of our more demanding Oracle environments and our DBAs reported that the latest VM we deployed (Oracle Linux 6.4) doesn't have HugePages enabled.  I would think this setting would need to be done at the Guest rather than the Host, but am not entirely sure.  Thank you in advance for any insight you can offer.

I couldn’t find any official information on the internet about protecting oracle database virtual machines with vSphere Site Replication. Can I replicate my single instance oracle database virtual machine to secondary site without any problem and inconsistency? Can be some inconsistencies from the perspective of Oracle with such replication?

 

Thank you very much, Any help is very appreciated.

 

Best Regards,

Rashad Afandiyev

vRealize Operations Management Pack for Oracle Database (Native)

vROps Community Members:

 

Blue Medora is currently developing a new VMware vRealize Operations Management Pack for Oracle Database.  This Management Pack will provide native monitoring of Oracle 11g and 12c databases. 

 

Note: This Management Pack is distinct from Blue Medora's vROps Management Pack for Oracle Enterprise Manager (Oracle EM) that also provides connector-based visibility into Oracle workloads managed by OEM.  This new (native) Management Pack for Oracle will not require that Oracle EM exist in the environment in order to enable vROps integration.

 

We plan to release the vROps MP for Oracle Database is Q2/16.


If vROps integration with Oracle Database is something that is relevant to you, Blue Medora's product management team is very interested in talking to you about what aspects of Oracle Database integrations you like to see surfaced in vROps, which specific Oracle Database features (RAC, ASM, PDB/CDB, etc) your organization most commonly leverages, as well as any specific troubleshooting / diagnostic use cases you have around integration Oracle Database based metric and alert information into vROps.

 

Please drop us a line at beta@bluemedora.com if you'd like to participate in a pre-release program for the vROps MP for Oracle Database.

Oracle 11g data guard on vmware

0

Hello,

 

I'm not all that familiar with Oracle databases. My DBA team is currently planning on configuring data guard for our 11g environment. Currently it is a single VM using VMDKs stored on iSCSI LUNs. I didn't set up the VM so I don't know why it is the way it is.

 

My Googling has not been productive, so does anyone have/know of any get instructions for 1. how you would normally set up an 11g VM and 2. how do you configure your VMware environment to support data guard.

 

Thanks!

Hi everyone, I was wondering if the new vsphere vmotion functionality (I mean, cross-vcenter-vmotion) could be a problem when I need to license an oracle virtual machine. Could someone help me to understand this tricky matter?

running RHEL 7 and Oracle e-Business Suite 12.2 on VMWare

How is an Oracle RAC on VMware setup supposed to deal with storage failure?

0
0

Hi all,

 

I am currently testing Oracle RAC running on a VMware vSphere 6 platform. The main purpose for us to use Oracle RAC is high availability and redundancy. We want to have the Oracle database up and running with zero interruption even if any single piece of hardware fails or is accidentally misconfigured.

 

Our setup is similar to that described in VMware's own whitepaper, in that we use VMDK disks with the write-sharing parameter enabled in order to attach VMDK disks to two RAC nodes at the same time. The setup in more detail:

 

We have two geographically separated sites. Let's call them SiteA and SiteB. Each site contains a vSphere 6 cluster and an EMC VNX storage unit. Let's call them ClusterA and StorageA, and ClusterB and StorageB. There is a fast WAN connection between the two sites, making it possible to have inter-site storage traffic. StorageA presents a lun called DatastoreA to both ClusterA and ClusterB. Likewise, StorageB presents a lun called DatastoreB to both ClusterA and ClusterB. These luns are formatted within VMware as VMFS-5 datastores.

 

We have two virtual machines, let's call them RAC1 and RAC2, both running Windows Server 2012 R2. RAC1 is running on ClusterA, and RAC2 is running on cluster B. The storage for the OS and application is presented by each VM's local storage unit.

 

Now we create the storage for the Oracle ASM disk groups. In the VMware settings of RAC1 we create two VMFS virtual disks of the same size, the first one on DatastoreA and the second on DatastoreB, making sure to enable multi-writer mode. Then in the VMware settings of RAC2, we connect the exact same disks, again enabling multi-writer mode. We repeat this entire process for all the other disks needed by Oracle RAC.

 

Now, our DBA can install Oracle RAC and Oracle ASM disk groups on the two servers. He creates disk groups which each contain two failure groups. One failure group contains all the disks on DatastoreA, while the other failure group contains all the disks on DatastoreB. Having finished the Oracle ASM and Oracle RAC configuration, he installs a database.

 

While testing this setup for resiliency against hardware failures, we wanted to know what happens in the event of a total loss of a single storage unit. To this end, we accessed the management console of StorageA and unpresented DatastoreA from both clusters, meaning both clusters suddenly lost connectivity with DatastoreA, creating a PDL (permanent device loss) situation.

 

What happens next is that both RAC1 and RAC2 completely freeze, and VMware generates a dialog box for each VM, like this:

 

 

After reading up on this, it seems to me that it is standard ESXi behaviour to freeze a virtual machine as soon as it tries to write to a VMDK file that is no longer available. Because both RAC1 and RAC2 are connected and try to write to a VMDK file that is no longer there, both VMs are automatically suspended by ESXi.

 

This is, of course, exactly what we DO NOT want to happen in a HA solution like Oracle RAC. The way it is now, a single storage failure or even a WAN failure would result in total loss of the database instance, even though one copy of all the database storage is still online. What am I missing here? What is the correct way to configure Oracle RAC on the VMware platform???

 

I would greatly appreciate any insights.

Any available best practice documents for Oracle 12c database on VMware?

I found the VMware guides for best practices of Oracle database 11.2 on VMware, anyone know or provide document

on best practices of Oracle 12c database on VMware, assuming OS is Linux. Also, anything on Oracle RAC 12c would

be great. Thanks


Host virtual adaptor not working

Hello,

 

I just installed VMware workstation pro 12.5.7 to run my Oracle training server. However, the host virtual adaptor doesn't want to be checked once I press "apply". I want to keep the virtual adaptor checked after clicking apply. How can I fix that.

 

I tried to elaborate my issue in the pictures attached below. Please read the titles and see them.

I enabled multi-writer in 2 vm's for the oracle asm, but after powering on the both the servers, the changes were gone from the configuration file.

i used vShpere Client version 6.0.0 build 6855219, and VMware vCenter Server Version 6.0.0 build 7462484.

Any suggestion why the changes were not reflected for multi-writer on both the vm's.

Hi

 

I have installed a single instance oracle (not oracle RAC just one node ) on vmware but just want to know what is vmware recommend for install an oracle production on a vm in cluster some questions such as :

 

Is there any issue due vmotion for that vm ?

Is that recommend to fix this machine on a specific host ?
