MIM Resource Sharing (MIM)
Issue/Introduction
Users would like to login to multiple lpars in a sysplex but getting the following message:
MIM1038I A=01E6 T=8FED90 contention with A=0031 T=8FED90 OWNS EXCL on MVSD
MIM1039I A=01E6 T=8FED90 needs EXCL SYSIKJUA XHAK
MIMQNAME member has the following defined:
SYSIKJUA GDIF=YES,
SCOPE=ALL,
EXEMPT=NO,
ECMF=YES,
RPTAFTER=0,
RPTCYCLE=15,
TRACE=NONE
Environment
Release : 12.5
Component : MII
Cause
The current configuration is propagating the SYSIKJUA request globally. This is due to having the definition of SCOPE=ALL.
Resolution
The SYSIKJUA ENQ should remain LOCAL. The same would be true for the SYSIKJBC ENQ.
Therefore, in order to allow multi-system logon, the following commands should be issued:
F MIM,DELQNAME QNAME=SYSIKJBC
F MIM,DELQNAME QNAME=SYSIKJUA
These are global commands, so they only need to issued on one system.
Remember to update the MIIQNAME member to comment/remove the related statements so that they are not picked up next time MIM is restarted.
