Rac clusterware compnents
Hi,
How to check the components of clusterware is running or not in oracle 11.1?
We used srvctl,got the following error.I tried to start the cluster ware.
[oracle@rac1 bin]$ *./srvctl status nodeapps -n rac1*
PRKO-2006 : Invalid node name: rac1
[oracle@rac1 bin]$ hostname
rac1.startoracle.com
[oracle@rac1 bin]$ *./srvctl status nodeapps -n rac1.startoracle.com*
PRKO-2006 : Invalid node name: rac1.startoracle.com
[oracle@rac1 bin]$ pwd
/u01/app/oracle/product/11.1.0/db_1/bin
[oracle@rac1 bin]$ srvctl status nodeapps -n rac1
PRKO-2006 : Invalid node name: rac1
[oracle@rac1 bin]$
Hi,
Can you please follow the below steps:
Symptoms
Before manually starting the database using 'srvctl instance -d ocs -i delphi-1", the "crs_stat -t" command was working fine on all nodes, problem started after manually starting the database using "srvctl" command.

Cause
OCR got corrupted.
Solution
To resolve this issue need to restore OCR from backup.
Oracle automatically takes backups of the OCR every 4 hours. Oracle also keeps the last 3
backups, up to 4 hours old, one day old, and one week old available. Here are the steps for restoring the OCR.
1. Find out what time the problem that the inconsistency in the OCR occurred.
2. Find an OCR backup from a time prior to when the inconsistency occurred.
To do this cd to $ORA_CRS_HOME/cdata/<cluster name>
[or]
Run $ORA_CRS_HOME/bin/ocrconfig -showbacku p (In this case you may not get any result)
Example:
# pwd
/t02/app/oracle/product/crs/cdata/crs_opcbsol
# ls -ltr
total 46560
-rw-r----- 1 root root 3960832 Apr 12 19:53 week.ocr
-rw-r----- 1 root root 3960832 Apr 13 03:53 day.ocr
-rw-r----- 1 root root 3960832 Apr 14 03:54 backup02.ocr
-rw-r----- 1 root root 3960832 Apr 14 03:54 day_.ocr
-rw-r----- 1 root root 3960832 Apr 14 07:54 backup01.ocr
-rw-r----- 1 root root 3960832 Apr 14 11:54 backup00.ocr
3. If you have a backup of the OCR from prior to the time of the inconsistency,
reboot the nodes in single user mode or runlevel 1. If you are unable to
reboot into single user mode for some reason, you can disable CRS with:
Sun or Linux:
/etc/init.d/init.crs disable
/etc/init.d/init.crs stop
HP-UX or HP Tru64::
/sbin/init.d/init.crs disable
/sbin/init.d/init.crs stop
IBM AIX:
/etc/init.crs disable
/etc/init.crs stop
4. After all nodes are rebooted in single user mode and/or you have verified that
CRS is not running (ps -ef | grep crs), restore the OCR with ocrconfig.
Example:
cd $ORA_CRS_HOME/bin
./ocrconfig -restore /t02/app/oracle/product/crs/cdata/crs_opcbsol/week.ocr
5. Re-enable CRS if it was disabled. Example:
Sun or Linux:
/etc/init.d/init.crs enable
HP-UX or HP Tru64::
/sbin/init.d/init.crs enable
IBM AIX:
/etc/init.crs enable
6. Reboot the nodes.
Best regards,
Rafi.

Oracle RAC + Clusterware and another Cluster with Clusterware for SAP
Hi,
I have some questions about implementation of Oracle RAC and Clusterware with SAP
For exemple, an architecture with 4 servers ( 2 real and 2 vritual ).
I would like to know if i can do this
2 servers for the first cluster.
First cluster is with Clusterware and Oracle RAC
This is for all the SAP Oracle databases environment
I think there is no problem here.
Now, with 2 others servers il would like to make another cluster (with also clusterware ) for SAP Central services (SCS) and enque replication server (ERS)
Because all architecture is for only one SAP environment with separate services.
1 for Database (cluster 1)
1 for Central services ( cluster 2, virtual machine )
1 for Dialogue Instance (no cluster)
To be clear, the second cluster is to make HA of central services SAP (SCS and ERS )
My question 2 are :
Is it a good job to do this ? or there is anything wrong ?
Do i have to install antoher clusterware for this 2 servers or i have to make anything with the existing clusterware + oracle RAC ??
Thank you very much for you help
Edited by: user12395221 on 29 déc. 2009 15:36Hi Givre,
have you checked: Providing High Availability for SAP Resources (http://www.oracle.com/technology/products/database/clusterware/pdf/sap-availability-on-rac-twp.pdf) available on otn.oracle.com/clusterware? Not being an SAP expert myself, I still think, this paper describes the configuration - at least partially - that you are trying to set up.
Just an idea. Thanks,

ORACLE RAC - Clusterware 11Gr1 -
Hi,
We are starting a fresh installation of an Oracle RAC database on:
IBM AIX 5.3
Processor Type: PowerPC_POWER7
Processor Implementation Mode: POWER 6
Processor Version: PV_6_Compat
Number Of Processors: 2
Processor Clock Speed: 3108 MHz
CPU Type: 64-bit
Kernel Type: 64-bit
We are changing the servers and installing new binaries: clusterware ,asm binary, rdbms binary. After that, database will be migrated to this server. The oracle clusterware will be on 11.1.0.7, ASM on 11.1.0.7 and RDMS on 10.2.0.4. We are installing exactly as it is in production now.
After the servers were release to the dba, configured the ocr and voting disks and the pre-reqs, during the installation we face an error on the second node, while running the root.sh. The installation went successfully, 100% and on the first node finished successfully and started the services. On the second node, while running the root.hs, it failed with the message :
--> Failure at final check of oracle CRS stack. 10
Checking the logs, we could see the following:

All the notes seems to point to and interface/interconnect problem, but we dont have any clue on what parameter or what checks we need to perform with Unix Team. Does anybody had this issue? Any clue on what may be need to be adjusted or configured to solve this issue? Following below is the interfaces of both servers: hodb001lernew and hodb002lernew:

I have Oracle Clusterware installed on a two node cluster. All Oracle components are functioning correctly. Problem is when I try to add my own application to the cluster, I am having major issues.
I am trying to have Samba launch and fail over on to different cluster nodes. Problem is I can not even get RAC to launch the Samba daemons -- I get a placement error.
CRS-1028: Dependency analysis failed because of:
'Resource in UNKNOWN state: SambaFailsafe'

Hi DNJ,
What you need to do is create temporary pfile with parameters like below
*.asm_diskgroups='DATA','FRA'
*.asm_diskstring='ORCL:*'
*.asm_power_limit=1
*.diagnostic_dest='/u01/app/oracle'
*.instance_type='asm'
*.large_pool_size=12M
*.remote_login_passwordfile='EXCLUSIVE' modify the above diskgroups to reflect your diskgroup configuration
then start the asm using that temporary pfile
SQL > startup pfile='/tmp/asmpfile.ora'once the asm instance started you can recreate the spfile
create spfile='+DATA' from pfile='/tmp/asmpfile.ora'shutdown the asm and start it back again
Hope this helps
Cheers -
Solaris 10g RAC Clusterware Raw device dd comand block size, sizing
Hi
We are in the process of installing clusterware for RAc on solaris 10. I have 4 luns 500mb each, we want to use them for the voting disks and ocr,
1. Which one do we use /dev/dsk or /dev/rdsk?
2) Also how do you erase the data to clear them out, I think you use the dd comand correct, but what is the full sytax to cllear the voiting disk and the ocr, do I need to specify a block size ??
3) Somebody was saying I should label the disks, just incase the controllers change the numbering if they ever get reconfigured, can this be done in SUN Solaris, if so can you give me an example, and do I specify the label as the ocr path??
Thanks
For all the info.1. Which one do we use /dev/dsk or /dev/rdsk?
$$
Please use Character Device ,This is general practice. However from 10.2.0.1 Block Device can also work.
# chown oracle:dba /dev/rdsk/cxtydzs6
# chmod 660 /dev/rdsk/cxtydzs6
2) Also how do you erase the data to clear them out, I think you use the dd comand correct, but what is the full sytax to cllear the voiting disk and the ocr, do I need to specify a block size ??
$$
do
dd if=/dev/zero of=/dev/ocr_disk$i bs=8192 count=25000 &
done
3) Somebody was saying I should label the disks, just incase the controllers change the numbering if they ever get reconfigured, can this be done in SUN Solaris, if so can you give me an example, and do I specify the label as the ocr path??
$$
Oracle recommends that you use a file name similar to dbname_raw.conf for this file.
The following example shows a sample mapping file for a two-instance RAC cluster. Some of the partitions use alternative symbolic link names. Make sure that the partition device file name that you specify identifies the same partition on all nodes.
system=/dev/rdsk/c2t1d1s3
sysaux=/dev/rdsk/c2t1d1s4
example=/dev/rdsk/c2t1d1s5
users=/dev/rdsk/c2t1d1s6

Hope this will help..

Oracle 11gR2 RAC clusterware not picking up ASM diskgroups
Hello: I had to deinstall a failed oracle 11gR2 rac cuslterware. But, not the asm disks are not in the OUI pick list. How can I resolve that?
The storage is on SAN partitions.Probably the install already put something on the disks.
Clean them with dd if=/dev/zero of=<your asm disks> bs=1M count=10

EBS R12 RAC Clusterware Installation.
Hi hussein/helios
The Oracle support has installed a RAC on our EBS Prod server but it was a POC(proof of concept) only. So the name was TEST RAC instance.
Now, we want to install the final config setup named PROD following the docs he made on the TEST POC. We will also
reuse all the files, directories, and raw devices used in TEST as PROD. Meaning all the traces of files and home dirs of TEST will be renamed to PROD, and change ownerships from oratest to oraprod.
First, we run deinstall of all the TEST install software like the CRS, ASM. We also delete the traces of TEST on inittab and oraInventory.
Then we now installed first the CRS_PROD. But to our surprise the CRS installation failed , it seems that it still
can see the "test" setup :(
Failure at SlfAccess(/u02/oracle/oratest/product/11.1.0/crs) with code -1Note the we already deleted the above directory since it belongs to the old setup, while the existing is:
/u02/oracle/oratprod/product/11.1.0/crs
My question is, how do you completely cleanup or deinstall all the previous traces of CRS?
Thanks a lot,

What advantages/disadv to having a none-rac db datafiles on rac clusterware
Hello,
We have a rac 10.2.0.3 with ocfs2 files on linux 4. We want to create a none-rac database on one of the rac nodes. The none-rac 10.2.0.4 is in its own new separate oracle home. Would it be a bad idea to use the existing ocfs2 mountpoints for the none-rac datafile locations? What would be adv/dis-adv to using ocfs2 for none-rac database files? Thank you.I will disagree of if a non-RAC database should use CFS or not. Since the file systems in use are clustered I see no reason to use a non-clustered file system and by using a CFS should the server the database is built on fail you can with a few minor edits start the database on the other node. If you used a traditional file system to hold the non-RAC database then its data files would not be accessible to the remaining node.
Placing the Oracle database on CFS then starting it from another node in the advent of failure is one of the early high availability (quick recovery) methods. This kind of set up was not uncommon in the VMS (DEC) world back in the late 1980's and early 1990's.
Also what if at a future data you determine you want to convert the database to RAC? It will be easier if the database is already on a CFS.

What is exactly clusterware in RAC
What is exactly clusterware in RAC? Is it same as having a shared disk or is it the RAC software itself?
I got confused while reading below sentence.
"If you are using Oracle clusterware you can add nodes dynamically. "
Can someone explain what it is?user6440749 wrote:
What is exactly clusterware in RAC? Is it same as having a shared disk or is it the RAC software itself?It is software used to coordinate one or more computers in a cluster.
It makes use of network and often makes use of a shared-writeable disk.
It makes sure all computers in a cluster, that are supposed to be operating in the cluster, can communicate. It provides diagnostics and takes action if the computer it protects is no longer functioning correctly as part of the cluster.
For RAC, Clusterware is the backbone software that provides the infrastructure for inter-instance communication. -
10g RAC on Oracle VM/Windows 2003 server
Is there any documentation/thread/blog which describes installation of 10g clusterware on Windows 2003 VM on Oracle VM 2.1.2 using just direct attached storage? I created 2 Windows 2003 VMs. For OCR and Voting disks, I created shared virtual disks. These disks are visible from both VMs. When I try to install clusterware, both VMs blue screen about 50% into install. The error in CRS logs points to OCR disks not being in correct format. I have tested same process with VMWare server and it works fine. Do I need to do something different for Oracle VM?
BTW this is not my first time installing RAC on Windows 2003. I have done more installations than I care to remember but always on physical servers. I followed the same process as I do for physical servers but it seems that Oracle VM does not like the shared virtual disks.
Thanks...Check out my articles at http://dbasupport.com on 10g R2 RAC Clusterware setup. I was able to do that on my vmware BUT I hope to have the very irritating ASM scenario done before my 4th Article.

Oracle 10g RAC on 2 VMware Windows 2003 images corrupts image
It happened twice on each of the 2 VMware workstation 5 on which I am trying to set up an Oracle 10g R2 RAC. After installing CRS and rebooting machine I lost access to the Network Connections and the Disk Management. Basically I have to create a new image. Before I start a third time I would appreciate advice or feedback from other users.
Also Configuration Assistants failed to install.

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes
Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit
Oracle RAC 11g , Clusterware 11g R2 , ASM with 5 raw disk ( 1- votting disk ,1- ocr files and 3 disk files)

Can you please tell any suggesstions to solve this issue? Is our hardware is not sufficient? Or any software settings has to be done?. I tried most of hte technique ,bt the problem still exists.

Oracle RAC , Clusterware 11g R2 64 Bit.i guess you have installed/configured RAC using VMware. i guess, the problem is with your RAM size. how much disk space and RAM size you have allocated for each machine?
which documentation you have followed? -
The CSSD does not start automatically on Non-RAC - AIX 5L
Hi all,
Database: Oracle 10.2.0.4
O.S AIX 5.3 TL 10
I am facing a problem with the CSSD Non-RAC/Clusterware.
When we restarted the server the service CSSD does not start automatically and there is no relevant messages in the log files of CSSD.
Running the "localconfig reset $ORACLE_HOME", execute successfully but does not start the CSSD.
Running "/etc/init.cssd start" - does not work, nothing happens when we run it
I manually ran "/etc/ init.cssd run" and the service CSSD (ossd.bin) was started without errors.
No errors on errpt from AIX.
I've opened a SR but I am waiting for response from Oracle.Hi,
I believe this problem is not with Oracle, but in AIX.It may be that one process that is starting on boot is holding the other process. You need to identify what is process/application.
Check the process on inittab that are already active and which are inactive they should be active.
One clue: Is very common process that is initiated in wait mode hold the boot server.
wait
When the init command enters the run level that matches the entry's run level,
start the process and wait for its termination.
All subsequent reads of the /etc/inittab file while the init
command is in the same run level will cause the init command to ignore this entry.http://publib.boulder.ibm.com/infocenter/aix/v6r1/index.jsp?topic=/com.ibm.aix.files/doc/aixfiles/inittab.htm
