SRVCTL (Server Control utility) commands in Oracle
srvctl commands – 12c
- To manage Oracle ASM on Oracle Database 12c installations, use SRVCTL in the Oracle Grid Infrastructure home for a cluster (Grid home). If you have Oracle RAC or Oracle Database installed, then you cannot use SRVCTL in the database home to manage Oracle ASM.
- You cannot use this command when OCR is stored in Oracle ASM because it will not stop Oracle ASM. To stop Oracle ASM you must shut down Oracle Clusterware.
