Removing an Oracle Grid Infrastructure Resource

This section contains the following procedures to remove an Oracle Grid Infrastructure resource:

• How to Remove a Dependency

• How to Delete the sun.resource Resource

How to Remove a Dependency

This procedure shows how to set the offline-restart dependency to remove a dependency.

1. Become superuser.
2. Display the current start dependency that the database has on the Oracle Grid Infrastructure storage_proxy resource.

   # Grid_home/bin/crsctl stat res ora.testdb.db -p | grep START_DEPENDENCIES
   START_DEPENDENCIES=hard(sun.grid-storage-proxy-rs) weak(type:ora.listener.type,global:type:ora.scan_listener.type,uniform:ora.ons,uniform:ora.eons)
   # clresource show -p resource_dependencies_offline_restart rac-server-proxy-rs
   === Resources ===
   
   Resource: rac-server-proxy-rs
   Resource_dependencies_offline_restart: crs-fw-rs scal-dg1-rs

3. Remove the offline-restart dependency on the SUNW.ScalDeviceGroup or SUNW.ScalMountPoint resource from the Oracle RAC instance proxy resource.

   This command clears the dependencies that the Oracle Grid Infrastructure database resource has on the Oracle Grid Infrastructure storage_proxy resource. Note that the command includes the minus (-) symbol.

   # clresource set -p resource_dependencies_offline_restart-=scal-dg1-rs rac-server-proxy-rs

4. Verify that the start dependency on the Oracle Grid Infrastructure resource is removed.

   # Grid_home/bin/crsctl stat res ora.testdb.db -p | grep START_DEPENDENCIES
   START_DEPENDENCIES=weak(type:ora.listener.type,global:type:ora.scan_listener.type,uniform:ora.ons,uniform:ora.eons)
   
   # clresource show -p resource_dependencies_offline_restart rac-server-proxy-rs
   
   === Resources ===
   
   Resource: rac-server-proxy-rs
   Resource_dependencies_offline_restart: crs-fw-rs

How to Delete the sun.resource Resource

1. Become superuser.
2. Ensure that the dependency is removed, as described in How to Remove a Dependency, and that sun.resource is stopped.

   # Grid_home/bin/crsctl stop res sun.scal-dg1-rs
   CRS-2673: Attempting to stop 'sun.scal-dg1-rs' on 'pnsx3'
   CRS-2673: Attempting to stop 'sun.scal-dg1-rs' on 'pnsx1'
   CRS-2673: Attempting to stop 'sun.scal-dg1-rss' on 'pnsx2'
   CRS-2677: Stop of 'sun.scal-dg1-rs' on 'pnsx3' succeeded
   CRS-2677: Stop of 'sun.scal-dg1-rs' on 'pnsx1' succeeded
   CRS-2677: Stop of 'sun.scal-dg1-rs' on 'pnsx2' succeeded

3. Delete sun.resource.

   # Grid_home/bin/crsctl delete res sun.scal-dg1-rs

4. Verify that sun.resource is deleted.

   # Grid_home/bin/crsctl stat res sun.scal-dg1-rs -p
   CRS-210: Could not find resource 'sun.scal-dg1-rs'.
