Hi, I will share Oracle RAC Administration Scripts in this post.



Read previous article before this.



Oracle DBA can administer Oracle Clusterware using the Oracle Clusterware Control (CRSCTL) utility.

I will continue to explain fundamental crsctl command.



To Query Voting disk location, execute following command. Set ASM profile before executing crsctl command.

[oracle@MehmetSalih ~]$ crsctl query css votedisk
## STATE File Universal Id File Name Disk group
