Aug 20, 2012I wanted to downgrade our 2 node RAC 11.2.0.3 to previous version11.2.0.2 on our test environment, so i could prepare to upgrade production later.
I followed oracle documentation and issued
'/u01/app/11.2.0.3/grid/crs/install/rootcrs.pl -downgrade -oldcrshome /u01/app/11.2.0/grid -version 11.2.0.2.0'
and both nodes and manually removed file in upgraded oracle home (rm -r u01/app/11.2.0.3).
This seems to have caused havoc and ASM and srvctl are no working. lsinvemntory lsinventory still poitns to removed oracle 11.2.0.3
I tried to set

RAC & Failsafe :: Single Node RAC - Configure Only One Server Instead Of Two Node?
Sep 13, 2012 I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

View 14 Replies View RelatedRAC & Failsafe :: Test Environment - SAN Migration?
Feb 15, 2012We have a RAC in a test environment.It's 2 nodes connecting to an IBM DS3512. The DS3512 has one pool of 8 hard disks (RAID10) which has been then sliced into logical drives:
2 x 1GB
then
2 * 400GB
I have been tasked with changing the current configuration as follow:
2 pools of 4HDs in a RAID10 configuration
Then from the first pool:
2 * 1GB
1 * 398GB
from 2nd pool:
1 * 400GB
What I intend to do:
1) shutdown
SQL> shutdown immediate;
./srvctl crs stop
2) backup
dd if=votingdisk of=voting_disk_backup
I already got backups of OCR in $CRS_HOME/cdata/crs/
3) Perform changes on SAN
4) recreate ocfs2 partitions
5) mount the disks to their folder.
6) recovery
recover voting from backup
recover ocr from backup
7) Turn service on again
./srvctl crs start
SQL> startup;
Would this scenario work. There can be some glitches like the disk names changing after the reconfiguration but I only need to modify fstab for that.

RAC & Failsafe :: Check How Many Sessions Connected To Particular Node
May 30, 2013I have few doubts in rac environment
1.In 2 node rac while adding datafile to tablespace if you forget to mention '+'then what will happen whether it is going to be create or it throws an error if it creates where exactly located and other node users how to work on that tablespace .what all steps to perform that datafile is useful for all node users.
2. In Rac environment how to check how many sessions connected to particular node.
3)In Rac any node is evicted due to network failure then after we rebuild the network .Is there any steps to do manually to access the failure node after rebuilding the network or it will automatically available in cluster group which service is perform this activity.
4.While configuring cluster ware you choose voting disk and ocr disk location and which redundancy you will choose suppose if you go for normal redundancy how many disks you can select for each file either one or two?

Apr 17, 2012I have the following problem on a 10.2.0.4 Oracle on AIX 1.6...
I have 2 RAC nodes as the node # 2 goes down, the VIP migrated correctly to the node # 1, but the listener # 1 do not see the change, and just resolve to the local ip.
The same does not apply in the reverse case, when it drops the node N 1, the listener attends to the fallen VIP node and migrated.The configuration is correct and identical in both nodes, according to the documentation, but I can not find a reasonable answer.
IP node # 1.

scm1or01-VIP 192.68.60.13
IP node # 2
scm1or02 192.168.60.12
scm1or01-VIP 192.168.60.14

I do not understand the reason, I've rebuilt the configuration of the listener, and netmgr netca tools, but the problem persists.
