Bug 39219430

During SNR/RAFT shard patches from Oracle AI Database 23.26.0 or 23.26.1 to 23.26.2, ORA-00604 and ORA-00904 errors may be encountered after patching the first shard.

Workaround:

Restart each shard after completing the patch. Additionally, restart the catalog database after patching the first shard; otherwise, the error ORA-02519: cannot perform cross-shard operation. Chunk "1" is unavailable may occur on the catalog database.
