Question:
IBM has released both hardware MCL and z/OS PTFs for the Meltdown security vulnerability. Both the MCL and z/OS fixes need to be applied prior to setting a new IEASYS parm (OSPROTECT=1) to mitigate meltdown. Need to know if the IBM APAR OA54807 will impact MICS?
Answer:
IBM APAR OA54807 has no impact on MICS.
This APAR adds new information at the end of a section, so it has no impact on current DAY030 processing.
Support for any new field(s) added by this APAR would be considered an enhancement for future inclusion into MICS.
