OCM 11g Preparation - Start, stop, configure and administer Oracle Grid Infrastructure

Configure and administer Grid Infrastructure can be done using the 2 main provided tools: "crsctl" and "srvctl".

• srvctl start/stop -> Start/Stop the cluster services.
• srvctl realocate -> Move some service, like the scan listener.
• srvctl status -> Check if service is running.
• srvctl config -> Display configuration.
• srvctl modify -> Change configuration.
• crsctl start/stop crs -> Start/Stop everything.
• crsctl start/stop has -> Start/Stop everything (for Oracle Restart).
• crsctl start/stop cluster -> Start/Stop everything (but OHASD).
• crsctl enable/disable/config -> Setup/check autostart.
• crsctl check -> Check status of main cluster base services.
• crsctl stat -> Check status of all servers/resources.
• ocrcheck -> Displays health of OCR
• ocrconfig -> Add/Remove/Backup OCR
• oifcfg -> Get/Set interfaces details
• olsnodes -> Print nodes information (vip/pinned/status/etc)

One good training to see if you are good with everything is:

1. Put your OCR / Voting Disk / +ASM SPFile inside the same diskgroup
2. Disappear with this diskgroup (override all disks with DD)
3. Bring it back online.
4. Take a rest.
