    CA IDMS Tuesday Tip by Edward Gorga, Principal Support Engineer for November 18, 2014

     

    An enhancement is available to exit 14 processing that can increase performance when running under zIIP. Optional bit 334 has been added which will skip all user exit 14 processing unless the program does a READY in update mode.  This can result in fewer swaps to and from the zIIP engine and the CP which can increase performance. To implement this new enhancement apply the following PTF:

    For 18.0 - RO66978

    For 18.5 - RO67058

     

    After applying the PTFs, activate the feature by coding the following optional bit in module RHDCOPTF:
