Specifies the parallel DL/I option used by ZDT/IMS functions running in BMP mode.
DL/I processing is performed in the BMP region.
All DL/I processing for the BMP is performed in the IMS™ control region. This prevents control region system 113 abends resulting from system X22 abends in the BMP region.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value specified on the HFM1POPD macro statement (if specified on that statement), or 0 (otherwise).

If you do not want the user to override the value you specify for this parameter, set UPARDLI=N.

Note: If you specify PARDLI=1, parallel DL/I is disabled. This can degrade performance.

For important information about the use of PARDLI and IMS control region abends, see PARDLI considerations.
