Oracle RAC on AIX gpfs.base

Oracle Database Enterprise Edition 11.2.0.2
IBM AIX 6.1
Hi
I need to install Oracle RAC on IBM AIX 6.1. For shared storage, we need gpfs.base as per documentation.
We are using Netapp SAN for storage.
Are there any alternatives to gpfs.base which can be used so that both nodes have access to same SAN storage ?

Hi;
Please check below note

If its not help i suggest connect wiht your vendor and also confirm this issue with support

RAC Newbie: Does RAC on AIX require HACMP?

I've never installed/configured RAC before, and the documentation I'm finding has conflicts on whether HACMP needs to be installed. One FAQ states the following:
Is HACMP needed for RAC on AIX 5.2 using GPFS file system?
The newest version of GPFS can be used without HACMP, if it is available for AIX 5.2 then you do not need HACMP
Another documentation article states HACMP is REQUIRED for 9i RAC on AIX.
Does anyone know the real answer to this question? Our configuration is AIX 5.3, GPFS 2.1, Oracle 9.2.0.4. Thanks in advance!!

The latest information from Oracle says:
Oracle9i RAC always requires HACMP.
HACMP is optional for Oracle Database 10g RAC.

Oracle´s File system over GPFS on Oracle RAC

Hi all,
I would like to know which Oracle´s File systems should be over GPFS on a Oracle RAC implementation.
Regards,
Sebastian.

You didn't provide info about DB relase and OS.
But probably you are talking about AIX OS (I can't see any reason to use GPFS on Linux for RAC and I don't remember if this FS was/is supported for RAC on Linux (check Certification Matrix for this information)). Oracle is provides only one shared "filesystem" for AIX and it is ASM.
Now it depends on DB version what options you can use.
Till 11g R2 you have to store OCR and Voting disks outside of ASM (So you needed to use either RAW devices or Cluster Filesystem which GPFS is). Since 11g R2 you can store these disks in ASM directly.
On Linux if you don't want to use ASM to store database files you can use OCFS2 clusterfile system.

Oracle RAC support NFS in AIX

May I ask a question...
My environment: SAP run on the AIX. may I use the Oracle RAC by NFS in AIX for Oracle HA ...?

Hi Dennie,
As far as I read from the development update SAP on Oracle, SAP supports NAS NSF with RAC 11.2 on all Unix platforms. Check the link http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d053aa41-75b6-2d10-95b5-9a961a5ae750?quicklink=ora&overridelayout=true
Check the statement in the note "1416773 - Oracle Direct NFS", below;
Advantages of Oracle Direct NFS :
Since NFS is a shared file system, you can also use this
implementation for Real Application Clusters (RACs). Oracle Direct NFS
recognizes if an instance is part of an RAC installation.

10G RAC on AIX without ASM & HACMP.

Hi,
I want to install ORACLE 10G RAC on AIX but I dont want ot use ASM or HACMP/GPFC.
Just want to install with CRS and RAW devices.Is it possible to install 10g RAC with CRS and RAW devices.
What is the best approach for this.
Regards
MMU

We're running CRS on AIX. No ASM or HACMP.
We do have the db datafiles on GPFS. We've also got one voting disk on GPFS and two on raw devices.

SAP ECC6.0 installation with Oracle RAC

Hi Expert,
Current we working on SAP ECC6.0 installation with Oracle 10G RAC on AIX 5.3. The RAC are running on two nodes (servers). And we are using GPFS filesystem (not running on HACMP).
Overall we had completed the Oracle RAC installation (CRS+RDBMS) and tested the oracle failover and it work find. Now we want to start with the SAP installation (with HA). In the SAP installation documentation, it did request to create a virtual hostname on the node and execute the sapinst scripts with below command line.
#./sapinst SAPINST_USE_HOSTNAME=ascs00
But if we are running on Oracle RAC + GPFS do we need to specify the virtual hostname? If not, which hostname i should use to install the HA for SAP? Please advice.
Regards.

And then I'd continue with the documentation at:
SAP on Oracle => SAP on Oracle Real Application Clusters (RAC)
There you can find several installation guides for windows/UNIX/Linux

RAC on AIX

Does RAC on AIX require HACMP or GPFS?. I think these are licensed products of IBM. Can't I use CRS without HACMP or GPFS?.
OS: AIX 6.1
DB : 10.2.0.4

Hi Boochi,
Yes. It is possible!
See on http://download.oracle.com/docs/cd/B19306_01/install.102/b14201/storage.htm#sthref602
You must use raw devices to store OCR and Voting disks and ASM to store database files

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:

This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.

Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

Hiii,
I am a fresher and I have a win 7 system 32 bit with oracle 11gR2.
I want to install RAC using two or more servers but I dont know too much about it.
I tried to search on google but all they are giving information in pieces(for win 7) or about Linux(Please tell me why its all Linux everywhere not windows).
Please let me know if there any site where I can find step by step installation from scratch.
What are basic requirements(/software if needed).
Thank you.

Hi,
First of all forget about Windows!! Oracle is mainly designed for Linux systems. Oracle runs as real multi-process on Linux machines whereas on Windows it runs as a single process with multi-thread.
Memory usage - huge pages,single CPU run queue, dnfs, storage systems... etc. lots of concepts exists.
Besides Windows is one of the most poorly designed operating systems, you should use it only to watch cute kitten movies on youtube... Believe me, you wouldn't want to learn Oracle on Windows...
So, install virtualbox and then setup Oracle Enterprise Linux on it as a first step... By the way you have to deal with DNS server for release 11.X, RAC, you may start with 10g for now.
ORACLE-BASE has all the installation steps explained detailly, search for "oracle base rac install" on google.
I also explained on my blog, but it is a little bit advanced installation using ZFS storage simulator. DNS server installation is also explained: http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

RAC on AIX 6.1 with HACMP

Hi
Can I have installation procedure and documents to Install 10gR2 RAC on AIX 6.1 using HACMP(for cluster control) instead of Oracle Clusterware. Is that possible ? anyone tried it before and share the experience.
Regards,
Akthar

Do you have any particular reason for using HACMP cluster control instead of CRS?
As you are going to install 10GR2 RAC So there is no need to use HACMP because 10G CRS can be installed without OS clusterware.
However CRS can be installed along with HACMP but oracle services should be controlled with CRS inly.

Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20

Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17
Cluster 2, node 2: 192.168.17.3 / 255.255.255.0 / VLAN 17
Cluster 3, node 1: 192.168.18.2 / 255.255.255.0 / VLAN 18
Cluster 3, node 2: 192.168.18.3 / 255.255.255.0 / VLAN 18
Cluster 4, node 1: 192.168.19.2 / 255.255.255.0 / VLAN 19
Cluster 4, node 2: 192.168.19.3 / 255.255.255.0 / VLAN 19
Which eats one VLAN per RAC cluster.

Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good.
