Specifying the ABORT Option
The ORDERLY option opens and closes unlinked server processes, permitting the
performance of any epilog processing.
Specifying the ABORT Option
The ABORT option aborts all TERMS for a faster shutdown operation. This command
specifies a shutdown in which terminals are aborted instead of stopped:
= SHUTDOWN2, MODE ABORT
The ABORT option enables send statements to a server class to complete, but the
TERM might be aborted before the server class can reply. Work does not necessarily
stop on transaction boundaries, so the status of the transaction is unknown.
If completing outstanding transactions is important to your application, use the
ORDERLY option. The ORDERLY option opens and closes unlinked server
processes, permitting the performance of any epilog processing.
Specifying the IMMEDIATE Option
To bring down the system as quickly as possible, use the IMMEDIATE option, as
shown in this example:
= SHUTDOWN2, MODE IMMEDIATE
This command uses the Guardian procedure call, STOP, to stop:
•
All running TCPs (that are locally controlled)
•
All server processes still running after the TCP is stopped
The IMMEDIATE option is the quickest way to shut down a PATHMON environment,
but you must consider these consequences before specifying this option:
•
If completed successfully, the IMMEDIATE option stops objects immediately,
regardless of the presence of pending requests and incomplete operations.
Unlinked server processes are not able to perform any epilog processing.
•
The status of any outstanding transactions is unknown.
