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

I used to use the replace option, until I found this behavior - nowit's always delete first. There might be a slight performance drag,but that seems small beans to me.

The replace option is convenient, but convenience is almost alwaysinversely proportional to some cost somewhere.

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.

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






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.
