We are applying some new MIM PTFs on our environment.
Is there any dynamic refresh on CAMIMGR that we can perform without stopping it, or do we need to IPL the system?
Release : 12.5
Component : MIM
F MIM,D LOADLIB <---see what libraries are in the MIM RMFIL
F MIM,LOADLIB RESETALTERNATE <--remove the existing alternate library
F MIM,LOADLIB SETALTERNATE=(new.load,DASD) <---add the new library containing maintenance
F MIM,LOADLIB REFRESHFROM=ALTERNATE <---refresh MIM with the new library

Regarding the recommended PTFs - the described problems have affected a very few customers, so you can issue the command even if they are not applied. The caveat is that if you do hit one of those problems, it is safest to have a plan in place to IPL the system in order to recover as quickly and cleanly as possible.
As alluded to above, the MIMRMFIL can be used physically or dynamically.
The MIMRMFIL DD can be added to your MIM STC, pointing to a standard, RECFM=FB,LREC=80 hlq.RMFIL dataset.
Doing so will retain any dataset names defined to the file across restarts. The risk here is that, if the file is rarely used, obsolete datasets may appear in your APFLIST (see KB 208281).
Using the MIMRMFIL without defining the DD statement allows for use of all the same commands. The limitation is that it will not hold any of those changes across restarts.
With either implementation, you will want to verify content and make any necessary changes prior to issuing the LOADLIB REFRESHFROM command.
