PARDLI considerations
The PARDLI parameter specifies the parallel DL/I option that FM/IMS functions use when they are run in BMP mode.
When this parameter is not specified on the FMN1POPD and FMN1POPI macro statements, FM/IMS passes a null value to the IMS™ region controller and IMS™ uses the default value, PARDLI=0.
With PARDLI=0, a system X22 abend in the BMP region causes the IMS™ control region to terminate with a U0113 abend.
A system X22 abend will occur in an
FM/IMS BMP region when:
- A TSO session executing an Edit or Browse in BMP mode is cancelled or times out.
- A batch function running in BMP mode is cancelled or times out.
If you want to prevent the control region being terminated with abend U0113 in the above-mentioned instances, you should set PARDLI=1. But note that this setting can degrade performance.
