The msys for Setup parmlib data set
There can be only one msys for Setup parmlib per sysplex in use. It contains
all committed members for all system profiles:
-
IEASYMxx members for all system profiles that have been included in a system
configuration update for the sysplex, one per LOADxx suffix used, containing
filters for each system profile covered
-
All other members with individual suffix per system profile
Notes:
-
When refresh is performed for the very first time, a RACF data set profile
is created, if it does not already exist, for msys for Setup, with universal
access READ.
-
If the data set profile already exists, it is altered to set universal
access READ. This is to avoid security violations during IPL when the msys
for Setup parmlib is in the active parmlib chain.
-
Important: If RACF is not used as the security product, you must make sure
that the equivalent definition is made for the particular security manager
that is in use.
The naming convention of the msys for Setup parmlib data sets is as follows:
<hlq>.MSYS.<sysplexname>.<PARMLIB | TEMPLIB | BKUPLIB>
Where:
-
<hlq>
-
is the high level qualifier you can set using policy msys for Setupparmlib.
The default is SYS1.
-
<sysplexname>
-
is the name you specified for the sysplex when you registered the sysplex.
