RE: What is the effect of removing *ALL from system value QALWUSRDMN?

The export procedure of the service program I mentioned is used by a
never ending job that repeatedly calling it every 60 seconds.  It cause
the QRPLOBJ lib to max out, which cause this job and other jobs that
need QRPLOBJ start to fail.

I found several other programs that is doing the same thing to create
the userspace.  Instead of changing all those programs, I just wonder
changing QALWUSRDMN system value would be a better approach (Doesn't
sound like it at the moment).

It makes sense if said I move a program object to production lib and
system auto put the existing one to QRPLOBJ because other job is using
the current object.  It just doesn't make sense to do this for QTEMP
library (May be IBM is doing this for thread safe programming language
like c).

Lim,

I'm kinda curious.  I still delete user spaces before reusing them. 
Someone on this list was suggesting that I use the option on QUSCRTUS to
replace it if it already exists.  Made sense to me, but it won't if I am
going to start experiencing what you are.

I still wonder what security risk they were attempting to guard against.

The program is using QUSPTRUS to get the user space pointer.  In that
case removing the *ALL entry is not going to work for me.  I just have
to change the program to delete the existing user space in QTEMP before
create it again.

It just seems weird for system to move the existing object in QTEMP to
QRPLOBJ lib.  What is the purpose of this action?

I am not sure what security risk they are trying to guard against.  I do
know that if you create a user space in a library that is not in this
system value, then you cannot use QUSPTRUS on it.  You would have to use
QUSRTVUS.  Once you get over pointer phobia and use QUSPTRUS one would
never go back to QUSRTVUS.  Using QUSRTVUS makes about as much sense as
if IBM dropped the ADD and the + capabilities in RPG and required you to
call some api passing several parameters like factor1, factor2, result,
and the error code data structure.
