MROFSE
The MROFSE system initialization parameter specifies whether you want to extend the lifetime of the long-running mirror to keep it allocated until the end of the task rather than after a user syncpoint for function shipping applications.
- MROFSE={NO|YES}
- Valid values are as follows:
- NO
- The lifetime of the MRO long-running mirror is not extended.
- YES
- The mirror task remains available to the application until the end of
the application's task. This extended long-running mirror saves the overhead
of re-attaching the mirror task following a user syncpoint.
This parameter is ignored for DPL requests (that is a DPL causes the session to be freed at the next syncpoint even if is has been kept for a previous sequence of syncpoints).
It should be used with caution especially if DPL requests with SYNCONRETURN or TRANSID are used. For additional information, see Long-running mirror tasks
Do not specify this value in the front-end region when long running tasks might be used to function-ship requests. This because a SEND session is unavailable for allocation to other tasks when unused. Specifying MROFSE=YES could prevent the connection from being released when contact has been lost with the back-end region, until the task terminates or issues a function-shipped request.
