Unable to change the database state from shutdown to mount

Description

After creating an offline backup of a standalone Oracle 12c Automatic Storage Management (ASM) database, SnapCenter fails to change the state of Oracle database from shutdown to mount.

Error message

Resource failed with error PL-SCO-20005: Unquiescing of database failed with error ORACLE-20001: Error trying to change state to MOUNTED for database instance database_instance.

Corrective action

The database state change fails because of an Oracle issue in the Oracle 12.1.0.2 standalone ASM configuration (Oracle bug 18894342). You must apply the Oracle patch 18894342. For information about this Oracle issue, see the Oracle Doc ID 1922908.1.
