Hi Paul,
This is an OPS/MVS 11.8 problem.
PROBLEM DESCRIPTION:
OPSMVS 11.8 by default uses ENCLAVES for performance purposes, which
may have adverse effects on performance tools, DB2, Websphere, and any
other products that use ENCLAVES.
CIRCUMVENTION:
For immediate relief, change option INITWME in opsview 4.1.1 to NO.
Then issue the following MVS command:
F OPSx,restart(WME) /* where OPSx is your opsmvs subsystem name */
Apply the associated PTF in order to disable enclave joins for the
time being, or remember to change your OPSxPAnn parameter member to
include the following statement to reflect this change:
T= OPSPRM_SET("initwme","no") The PTF will not affect the INITWME
Parameter, but will disable any newjoins.
