Oracle Clusterware Administration Quick Reference

Posted By Sagar Patil

Sequence of events to bring cluster database back..

1.    Start all services using “start -nodeapps”
2.    Start ASM instnace using “srvctl start asm -n (node)”
3.    Start RAC instances using “srvctl start instance -d (database) -I (instance)”
4.    Finish up by bringing our load balanced/TAF service online “srvctl start service -d orcl -s RAC”

List of nodes and other information for all nodes participating in the cluster:

[oracle@oradb4 oracle]$ olsnodes -n
oradb4 oradb3 oradb2 oradb1

List all nodes participating in the cluster with their assigned node numbers:

[oracle@oradb4 tmp]$ olsnodes -n
oradb4 1 oradb3 2 oradb2 3 oradb1 4

List all nodes participating in the cluster with the private interconnect assigned to each node:

[oracle@oradb4 tmp]$ olsnodes -p
oradb4 oradb4-priv oradb3 oradb3-priv oradb2 oradb2-priv oradb1 oradb1-pr

Check the health of the Oracle Clusterware daemon processes:

[oracle@oradb4 oracle]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

Query and administer css vote disks :

[root@oradb4 root]# crsctl add css votedisk /u03/oradata/ CssVoteDisk.dbf
Now formatting voting disk: /u03/oradata/CssVoteDisk.dbfRead -1 bytes of 512 at offset 0 in voting device (CssVoteDisk.dbf) successful addition of votedisk /u03/oradata/CssVoteDisk.dbf

For dynamic state dump of the CRS:

[root@oradb4 root]# crsctl debug statedump crs
dumping State for crs objects Dynamic state dump information is appended to the crsd log file located in the $ORA_CRS_HOME/log/oradb4/crsd directory.

Verify the Oracle Clusterware version:

[oracle@oradb4 log]$ crsctl query crs softwareversion
CRS software version on node [oradb4] is []

Verify the current version of Oracle Clusterware being used:

[oracle@oradb4 log]$ crsctl query crs activeversion
CRS active version on the cluster is []
