This section describes the guidelines for installing and discarding
DB2ENTRY definitions and the implications of interruptions in partial activity.
- You can install a DB2ENTRY only if you have previously installed a DB2CONN.
- You can install a new DB2®ENTRY at any time, even when the CICS® DB2 adapter
is connected to DB2.
- You can reinstall (by replacing an existing DB2ENTRY) only when the DB2ENTRY
is disabled and no transaction is using it. Use the SET DB2ENTRY DISABLED
command to quiesce activity and disable the entry. New transactions trying
to use the DB2ENTRY are routed to the pool, abended, or returned an SQLCODE,
dependent on the setting of the DISABLEDACT keyword when the DB2ENTRY is disabled.
- You can discard a DB2ENTRY only if it is disabled. Use the SET DB2ENTRY
DISABLED command to quiesce activity and disable the entry. New transactions
trying to use the DB2ENTRY are routed to the pool, abended, or returned an
SQLCODE, dependent on the setting of the DISABLEDACT keyword when the DB2ENTRY
is disabled.
If you discard a DB2ENTRY, you could make the corresponding
DB2TRAN an 'orphan'. If you then run a transaction, a message is sent to the
CDB2 transient data destination, and the request is rerouted to the pool.
