Making Oracle ASM Available to Earlier Oracle Database Releases
To use Oracle ASM with Oracle Database releases earlier than Oracle Database 12c Release 2 (12.2), you must pin all the cluster nodes.
After you install Oracle Grid Infrastructure 18c or later release, if you want to use Oracle ASM to provide storage service for Oracle Database releases that are earlier than Oracle Database 12c Release 2 (12.2), then you must use the following command to pin the nodes:
$ crsctl pin css -n node1 node2
This setting updates the oratab
file for Oracle ASM entries.
You can check the pinned nodes using the following command:
$ ./olsnodes -t -n
Note:
Restart Oracle ASM to load the updatedoratab
file.
