Clear Statement Cache

For each connection in the connection pool, clears the statement cache of prepared and callable statements.

Suspends a data source that has the health state of Running, including disconnecting all current connection users. All current connections are closed and recreated. If successful, the health state is set to Suspended.

Resume

Restores all access to and operations on a data source that has a health state of Suspended. If successful, the health state is set to Running.

This state includes conditions when the database server is not available and the data source is created (creation retry must be enabled) or when all connections have failed connection tests (on creation, on reserve, or periodic testing).

  • Suspended

    - the data source has been disabled.

  • Shutdown

    - the data source is shutdown and all database connections have been closed.

  • Overloaded
