Opatchauto72030 - Execute In Nonrolling Mode Exclusive _top_

Exclusive access means the patching process takes full control of the Oracle home. No other operations (backups, other patches, or administrative tasks) can run concurrently. This ensures patch integrity.

Ensure the filesystem hosting your Grid Infrastructure home ( /u01 or equivalent) has ample free space. A lack of space to create backup configurations during rootcrs.sh executions frequently drops execution codes down to 255.

While the -nonrolling flag resolves the 72030 error, other issues can arise. Administrators should be aware of the following:

When the CRS home is shared, it is physically the same directory being accessed by multiple nodes. Performing a rolling patch in this scenario would be inherently risky. If one node were to be patched, it would potentially alter the software binaries on the shared storage while other nodes are still running the old software and accessing those same files. This could cause process crashes, version mismatches, and severe cluster instability. Therefore, OPatchAuto strictly enforces a non-rolling approach. To override the default rolling mode and use the non-rolling alternative, you must specify the -nonrolling flag.

Ensure the patch you are applying supports non-rolling application, although most RUs (Release Updates) and RURs (Release Update Revisions) do. Exclusive access means the patching process takes full
