4 Shutting Down and Starting True Cache

You can shut down and start an existing True Cache.

Note:

Perform these tasks on the True Cache container database (CDB), not on the pluggable database (PDB).

4.1 Shutting Down True Cache

To shut down True Cache, use the SHUTDOWN command.

Note:

Before shutting down True Cache for planned maintenance, stop the database application service on True Cache.
connect / as SYSDBA;
SHUTDOWN;

When you shut down True Cache, the cached content is lost. When you restart True Cache, it fetches the content again from the primary database.

4.2 Starting True Cache

To start an existing True Cache, use the STARTUP command. 

connect / as SYSDBA;
STARTUP;

Work is automatically routed to True Cache when it declares that it's ready to support the True Cache service.
