Question re: Grid Infrastructure 11.2.0.3 on IBM Power7+ server - IBM HACMP

My company is preparing to create a new Oracle RAC cluster (11gR2) on IBM Power7 hardware running AIX (either 6.1 or 7.1, not sure yet). We currently have 2 11gR2 clusters running on older hardware.
I am being asked by IBM and our AIX sys admin about using IBM's HACMP software to cluster the hardware at the OS level. I have researched the certification matrix on MOS, and have found that we CAN do this. But I am being asked if we SHOULD do this.
Any links to Oracle documentation and/or MOS articles on this topic would be appreciated. I have never used HACMP in any of our past clusters, and would like to avoid the additional complexity. But I need to be able to "prove" my case.
Any and all information based on forum users' experiences will be greatly appreciated. Thank you in advance for your assistance with this question/decision.

Hi,
When you say cluster the hardware...what exactly does that mean? What hardware?
When using RAC on AIX with ASM, CRS will manage all of your resources. HACMP is not required and even if you did install it, then would it manage?
CRS will manage your scan, scan vip, vip and the storage will be shared on ASM. So the question remains as to what will HACMP manage, if you wish to install it?

If not using HACMP then HACMP filesets must not be installed.

Install a grid infrastructure for a cluster for single node Windows Server

Hello,
Can you suggest me how to install a Oracle Single Node RAC 11g on a Windows Server 2008 x64 bits? It's for testing purposes and I don't need two nodes. I know that Linux is better, but my company only uses Windows servers. Our former consultant was able to do it, but didn't tell us how to and that server was lost.
I know that we have to install first Grid Infrastructure. Running the "Oracle Grid Infrastructure" installer, I could successfully install a "Grid Infrastructure for a Standalone Server". But that grid is not for a RAC database. When trying to install the Database software, it allowed to me to only install "Single instance database", not "Real Application Cluster database installation".
Running the "Oracle Grid Infrastructure" installer, I tried to select option:
"Install and Configure Grid Infrastructure for a Cluster" -> Typical Installation:
SCAN Name: SRVORAC-cluster
Validating SCAN information
INS-40922 Invalid SCAN Name - unresolvable to IP address.
Is it possible to install a grid infrastructure for a cluster for a single-node or one-node Windows Server ?

HI,
You probably have misconception about Single node RAC. This feature does not need that you have only one physical machine in a RAC, it actually means that in a RAC environment (2 or more nodes), you can run your database on only one node(single instance) and then later you can move this single instance to any other node of the RAC (so that you can do some patching on this node making your database available all the time). This also has some other benefits, see bellow.

Which listener should be used in a standalone grid infrastructure env?

gurus:
I installed a 11.2.0.2 standalone grid infrastructure on a linux box and created a database manually. I then used netca to create my listener which created 2 listener files:
a. under my DB home:
aml6:/u00/app/oracle/product/11.2.0/dbhome_1/network/admin > cat listener.ora
# listener.ora Network Configuration File: /u00/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER_ETL =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = aml6.lynk.lynksystems.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
ADR_BASE_LISTENER_ETL = /u00/app/oracle
b. under my grid home:
aml6:/u00/app/11.2.0/grid/network/admin > cat listener.ora
LISTENER_ETL=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_ETL)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_ETL=ON # line added by Agent
I observed that the one under my DB home was the one that really got used when I tried to logon to a database.
Here are my questions:
1. what is the use for the listener under my DB home?
2. what is the use for the listener under my grid home?
3. the grid infrastructure document says that the default home for listener and tnsnames files are grid home, however, it seemed that I have to use the listener under my db home directory.
4. which listener is the ASM instance use?
Thanks a lot for your help.

Thanks Levi and Sebastian.
We have separate listeners in DB homes for Stand Alone grids.
Cluster Grids have got the listeners (SCAN..etc) running out of Grid Home. Still, we have exceptions for the Cluster grid for EBS databases where SCAN is not supported yet and still have a separate listeners for the databases.
This OTN doc also describes a listener in the DB home: http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/install/gridinstss/gridinstss.htm
Hi Raj,
In this OBE, the author explains why he is setting a new Listener for ASM.
To Configure EM Database Control to manage ASM, perform the following steps:
To manage the ASM instance in Enterprise Manager Database Control. you must configure the ASM Instance as a target.
When you configure the ASM target, you must provide the port for the ASM listener.
The Grid Infrastructure installs a listener by default on port 1521, and configures the ASM instance to use this listener.
In this tutorial the database is already installed and has a listener configured on port 1521, the Grid Infrastructure places a listener on port 1522 and the ASM instance is registered with the grid listener.Before Install Grid Infrastructure he already had a database running with the Listener configured and running.
To ensure that the service of ASM will be registered in the Listener of same release he set a new Listener using GUI HOME.
This procedure is correct because the Grid Infrastructure (ASM) is the highest release (So, it's necessary configure Listener in same release), to not use a Listener with prior to release of the Grid Infrastructure(ASM) he created new Listener.
He also could deconfigure the Listener of Oracle Home (database) and configure in the GUI Home. It's a matter of choice.
Observing requirement of the paragraph below, we can set listener from anywhere there is no restriction, it is a matter of best practices only.
The release of the listener must be the same as or later than the latest release of all Oracle databases being serviced through the listener.Cheers,
Levi Pereira

Uninstall Oracle 11gr2 RAC database in grid infrastructure

Hi all,
After several attempt to install my Oracle database RAC with grid infrastructure, i want now to do a fresh installation as i have attempted 3 times and now i have all the procedure on installing the database and RAC.
Actually i have installed it correctly but now i want to cleanup my server and remove all oracle installation directory and do a fresh installation.
My question is what is the procedure to uninstall an Oracle RAC database and Clusterware with grid infrastucture and cleanup oracle base installation.
The architecture is:
GRID and clusterware: Oracle grid 11gR2
Database: Oracle database 11gR2
Database and grid storage: ASM
OS: linux centos 6
Thank you.
Raluce.

The deinstallation of Oracle GI could be not so easy thing to do, because it contains many components one should be aware of. The proper deinstall is important because it will safe you from many issues with next install on these servers
In general we need to be sure that:
1. all sowftware stopped properly
2. removed from oraInventory
3. binaries removed
4. /etc/oracle cleared
5. ocr and votes cleared using dd
6. /etc/oratab updated
7. .profile updated
8. init.d files in /etc/ cleard
Usually its recommended to use deconfigure scripts, if they fails for some reason, the manual procedure should be followed.
How to Deconfigure/Reconfigure(Rebuild OCR) or Deinstall Grid Infrastructure [ID 1377349.1]

As general recommendation its good idea to save your crs configuration for future reference.

Grid Infrastructure 11.2.0.3 install fails with public & private subnet

Specify Network Interface Usage
Interface Name: eth0 Subnet: 192.168.1.0 Public
Interface Name: eth1 Subnet: 192.168.1.0 Private
Using the Advanced Installation ->
No GNS ->
I'm getting error [ins-41113] Specified public and private interfaces are configured on the same subnet: 192.168.1.0 Why is this an error because Oracle Documentation e17212/typinst.htm says the following:
A Single Client Acess Name (SCAN) for the cluster , wich the following characteristics:
* Three static IP address; however I want to use only two static IP address because I am not using DNS I'm using /etc/hosts file.
* On the same subnet as all other public IP addresses, VIP addresses, and SCAN addresses.
Please advise because I was able to install Grid Infrastructure 11.2.0.2 using the same configuration with no problems. Now that I am using Oracle 11.2.0.3 I'm encountering this problem.

Hi,
I appreciate insight with respect to Why Does it work in Oracle Grid Infrastructure 11.2.0.2 and not in 11.2.0.3 ?Some things that are not supported, are sometimes allowed by Oracle Product Software (I can say it's bug), but still desupported.
See this example.
In 11.2.0.1 and 11.2.0.2 it's possible add releases prior to 11.2 of Oracle Database to be managed by Oracle Restart. But It's not certified.
See this thread.
{message:id=9270783}
In 11.2.0.3 Oracle solved this issue don't allowing do that and created a new msg error :
PRCD-1245 : Addition of database version 11.2.0.3.0 is not allowed using srvctl version 10.2.0.0.0So, like example above in 11.2.0.1 and 11.2.0.2 it's not supported use same subnet to private and public network, but it's allowed by Oracle Product Software, now it's not allowed by Oracle Product Software
The install guide will tell you the following requirements private IP address must satisfy the following requirements:
*1. Must be separate from the public network*
2. Must be accessible on the same network interface on each node
3. Must have a unique address on each node
4. Must be specified in the /etc/hosts file on each node
The Best Pratices recommendation is to use the TCP/IP standard for non-routeable networks. Reserved address ranges for private (non-routed) use (see TCP/IP RFC 1918):
* 10.0.0.0 -> 10.255.255.255
* 172.16.0.0 -> 172.31.255.255
* 192.168.0.0 -> 192.168.255.255
Cluvfy will give you an error if you do not have your private interconnect in the ranges above.
You should not ignore this error. If you are using an IP address in the range used for the public network for the private network interfaces, you are pretty much messing up the IP addressing, and possibly the routing tables, for the rest of the corporation. IP addresses are a sparse commodity, use them wisely. If you use them on a non-routable network, there is nothing to prevent someone else to go and use them in the normal corporate network, and then when those RAC nodes find out that there is another path to that address range (through RIP), they just might start sending traffic to those other IP addresses instead of the interconnect. This is just a bad idea.

Potential Versioning Differences Between Storage Server and Grid Infrastructure/DB

Hello.
While awaiting my MOS CSI access to be approved For Exadata HW issues so I can open an SR, I have a question. We are about to apply QFSDP for BP 22 on one of our full RACK X3 Exadta servers. Currently, the Grid Infrastructure (GI)/DB SW is at 11.2.0.3.0 and teh storage SW is at 11.2.3.2. Our last BP was 19. BEFORE we apply the BP 22, we want to upgrade the clusterware to 12c - but not the DB (that will come later). This is a high level question which I have discussed with several Oracle techs, but wanted to see what the experience/opinion is while I await access to my CSI. Can you have your Grid Infrastructure (GI) running at a higher version than that of your your storage server? The tech I spoke to said that all GI/DB SW should be at a version that is NO GREATER than that of the storage server - meaning a 12c version of the GI would not be compatible with a lowere version of the storage server. Thank you in advacne for any guidance.
Regards,
Matt

Hi Matt,
Seems you want to do a lot in one go here.
Maybe you should look at Doc ID 888828.1, Doc ID 1537407.1 and Doc ID 1373255.1 for a start.
For 12c (grid and rdbms) on Exadata it is recommended to upgrade your FW to 12.1.1.1.0 first.
My advice would be to patch up 11g to BP22 and when done start planning the 12c upgrade (keeping the 11g dbhome).

Tycho

How reInstall Gride Infrastructure and Use old ASM disk groups

<pre>Hello to all
I installed Grig Infrastructure 11gR2 on a standalone server (OS is Linux)
and I configured ASM and my database created on ASM
Conceive that my OS disk corrupted and OS doesn't start and the Gride Home is on that disk,
and I have to install OS again
My ASM disks are safe , Now how can I install Grig Infrastructure again somehow that it can use previous ASM disks
and disk groups and I don't oblige to create my database again ?
In the step 2 of installing Gride Infrastructure it has four options
<pre>
1.Install and configure Oracle Grid Infrastructure for a Cluster
2.Configure Oracle Grid Infrastructure for a Standalone Server
3.Upgrade Oracle Gride Infrastructure or Oracle Automatice Storage Management
4.Install Oracle Gride Infrastructure Software Only
</pre>
If I select the option 2 it wants to create a disk group again
I guess that I need to select option 4 and then do some configuration but I don't know what I must configure
Do you know answer of my question , if yes please explain it's stages
Thank you so much
</pre>

Hi,
no you are not obliged to recreate your database again. However there is a small flaw in the installation procedure, which does not make it 100% easy...
When you installed the Oracle Restart (Standalone GI), your ASM diskgroup will contain the SPFILE of the ASM instance. And this is exactly the small flaw you will be encountering. So you have 2 options for "recovery":
1.) Do a software only install (4), and run roothas.pl. This however will not create any ASM entries. You would have to add it manually (using srvctl) and you can specify the ASM Spfile with the srvctl command. Problem here is however to have to know where your ASM spfile has been. If you have a backup of your OLR and a backup of the GPNP profile, this might be easier to find out.
2.) Do a new installation (2) and configure a new diskgroup (with a "spare" disk or small lun and a new name), that Oracle restart creates ASM instance and the new ASMSpfile for you.
Then you can simply mount the diskgroup containing your database additionally. You then shoudl however move your new ASMSpfile to the new diskgroup (or simply exchange it with the existing one). In this case it is easier to find out where it was - however you will need a spare (though small) LUN for the new spfile (temporarily, until you exchange it).
In either case after you have your ASM instance back (and access to your old diskgroup), you have to reregister your database and services - if you do not have an OLR backup.
Again => It is doable and you can simply mount the ASM diskgroup containing your database. However I suggest you try this one time to know what really needs to be done in this case.

Configure Oracle Grid Infrastructure for a standalone server

As I understand and as the following doc indicated, to install Oracle database, I'd have to install Grid Infrastructure first. I am not configuring RAC/cluster, only on a standalone server.
I executed runinstaller, and choose " install the software only", then after I selected "configure oralce grid infrastructure for a standalone server", I am getting the following error:
[INS-40410] The installer has detected a configured instance of Oracle Grid Infrastructure software on the system
Please advice how this instance have been configured, and how to remove it before I can proceed?
Thanks!

What happens after root.sh - grid infrastructure installation

Hi,
I'm trying to install 11.2.0.2 grid infrastructure.
I got ok until root.sh, during root.sh I got some error on the asm disks for the ocr - I think it's a permissions issue.
Anyway - sysadmin fixed it and I know I now need to deconfigure root.sh -force and then run it root.sh again.
however - sysadmin also reboot my server so - the installer is GONE.
My question is - let say I get the root.sh run smothly, what is the installer doing after I press ok on the root.sh screen (which I now of course don't have...)
can this be run in some script as well?
Thanks!

just to close this thread - the answer I gor from oracle support was:
Hello,
The OUI will execute cluvfy after root.sh is acknowledge to be run successfully. You can manually execute cluvfy from grid_home with -post option to validate the installation.
check also with commands that all resources are online:
crsctl stat res -init
crsctl stat res -t
Thanks and regards,

Oracle 11.2 standalone grid infrastructure - change hostname

Hi
I have changed hostname of my server running RHEL 5.3 with Oracle 11.2 Grid Infrastructure (standalone). After I changed the hostname of the server, the crs daemon stopped working and I cannot connect to my +ASM instance any longer.
In Oracle 10g2it was enough to run localconfig delete, localconfig add
What should I do in 11.2 ?
Thanks for help
Groxy

Hi Groxy,
I recently found myself asking the same question and after a fair amount of digging around I found a way to do it. Your question is now a few months old, so maybe you have found the solution already, but if not the key is using roothas.pl rather than localconfig. I have written a brief blog post covering the approach I used, so please check that out if you want more information.

Grid infrastructure configuration failed

Hi all experts,
We are upgrading from 11.2.0.3 to 11.2.0.4 to clusterware. Upgrade went smooth but it showed errors that Oracle cluster verification utility failed and configure oracle grid infrastructure for a cluster failed. I checked crs log and all but it does not show any errors. Can anyone tell me where is the location of CVU utility log files? I will appreciate your feed back.

Thanks sharma for your help as you do always. I have one quick question. When i type below command to check resource , it does not show anything . Do i have to do any set up for new GRID HOME in windows? What i need to do so i can run this command from new grid home?
enctcorl status resource -t
'enctcorl' is not recognized as an internal or external command,
operable program or batch file.
i used to run this from previous grid home and it run ok but after upgrade , i cannot run.

Is Grid Infrastructure free?

In my understanding, Oracle Grid Infrastructure is free to use in a cluster to manage both Oracle and non-Oracle applications, if we use Grid Infrastructure to manage at lease one licensed Oracle Database.
Hovewer, I am not able to find any official statement about Oracle Grid Infrastructure 11.2 licensing.
Am I right? Could you please give me link to metalink notes or oracle docs about 11.2 GI licensing ?
Thanks,
Andrea

11.2 Standalone Grid Infrastructure installation to Clustered Grid Insall

Quick question:
Currently we have a 11.2.0.1 standalone grid infrastructure installation with ASM instance running on server a1. And there are few databases running under the +ASM instance on a1. We are planning to make a1, a2 as a 2-node real application cluster. Is there a way to convert the standalone grid infrastructure installation on server a1 to a clustered grid infrastructure installation along with a2 with out de-installing the existing standalone grid infrastructure on a1 and re-installing freshly?
Thanks

Hi Boochi,
Thanks for responding. May be I am not clear enough in my post. Database conversion will be the next step, my question is about the actual grid infrastructure installation...Currently a1 server has been configured to work as standalone grid infrastructure, but our requirement is to convert to a 2-node RAC with server a2. Generally, I would go by de-installing the existing standalone grid infrastructure running on a1 and re-install the clustered-grid infrastructure with nodes a1 and a2. I am wondering if there is a way without de-installing the existing standalone grid infrastructure??

Oracle Grid Infrastructure for Windows.

Hi, i am very new to Oracle world, please forgive me if my question is too silly.
I am currently practice Oracle on my Windows 2008 server. When i try to install ASM, i found i have to install 'Oracle Grid Infrastructure'. ok, i went o Oracle download page, i found the 'Oracle Grid Infrastructure 11g Release 2 (11.2.0.1.0)'. But it only has Linux\Solaris\HP-UX\AIX\zLinux to choose from. Where can I found the Windows version?

Select the media pack for your version of oracle. When you drill down there will be several zip files for download. the first two are for the database, the third is ASM/GI

Oracle Grid Infrastructure

Hi,
I'm trying to convince our systems administrator about the need for us to use Oracle Grid Infrastructure with our 11gR2 database installation. I find that I'm not really sure what the main advantages are, could you help please?
- What is the main advantage of Oracle Grid Infrastructure, what is it that will make me use it as opposed to conventional method of storage?
Any documentation recommendation would help please. I have been on the 11gR2 course and I have Oracle documentation but I am unable to see (or maybe it is lack of understanding) what is the main thing that will make us use it over an installation that uses file system storage.
thanks

I actually meant to copy and paste the benefits of using ASM out of it which answers the question OP had of using GRID for storage, (I had actually typed "see this bit") and was using the link as the reference, nont sure why I didnt, I mustnt have pasted properly into the post before posting. GRID as we know offers the asm usage which is the storage part of it. I have that link in my notes for reference when looking for the arguments to use ASM. From that link
•Provides automatic load balancing over all the available disks, thus reducing hot spots in the file system
•Prevents fragmentation of disks, so you don't need to manually relocate data to tune I/O performance
•Adding disks is straight forward - ASM automatically performs online disk reorganization when you add or remove storage
•Uses redundancy features available in intelligent storage arrays
•The storage system can store all types of database files
•Using disk group makes configuration easier, as files are placed into disk groups
•ASM provides stripping and mirroring (fine and coarse gain - see below)
•ASM and non-ASM oracle files can coexist
•ASM is free!!!!!!!!!!!!!
