Apply remote (APYRMT) parameter

You can use the APYRMT parameter to specify whether the other CHGQRYA options should be applied to the associated remote system jobs that are used in the processing of the distributed query requests.

The APYRMT parameter has the following options:

*YES—apply the CHGQRYA options to remote jobs. This requires that the remote job have authority to use the CHGQRYA command. Otherwise, an error is signalled to the remote job.
*NO—apply the CHGQRYA options only locally.

The following example prevents the CHGQRYA options from being applied remotely:

CHGQRYA DEGREE(*NONE) APYRMT(*NO)

In this case, symmetric multiprocessing (SMP) parallel support is prevented on the coordinator node, but the remote systems are allowed to choose their own parallel degree.

In addition to these parameters, you should be aware of how the parameter Query Time Limit (QRYTIMLMT) works. The time limit specified on the parameter is applied to each step (local and remote) of the distributed query; it is not applied to the entire query. Therefore, it is possible for one query step to encounter the time limit; whereas, another step can continue without problems. While the time limit option can be quite useful, it should be used with caution on distributed queries.
