Automatic Shutdown

CA Datacom CICS Services is designed to be shut down automatically through the PLT. Automatic, non-immediate shutdown consists of two phases. During the first phase, no new transactions are accepted, but the following current operations are processed to completion:

• Applications specified in the DFHXLT Table
• Active conversational transactions
• CA Datacom/DB requests having or waiting for exclusive control

When all active transactions have been processed, the second phase of the automatic shutdown is invoked. The second phase consists of the following steps:

1. All opened URTs are closed.
2. All connected MUFs are disconnected.
3. Statistics, like those resulting from the following commands, are written to the Message Log file (DBOC) and reset:
   • DBOC INQ=STATS
   • DBOC INQ=CODES
   • DBOC INQ=USERS
4. All CICS resources used by CA Datacom CICS Services are released.
