RE: CLRLIB QRPLOBJ?? (was Re: IPL regains storage.......but)

With all due respect, I think that the below statement is in error.  The
PTF process (with respect  to object naming) is essentially unchanged form
the System/38.  The PTF objects are given a pseudo name in their own
library with loaded.  Then applied temporarily, the real object gets
another pseudo name in the same library, and the first pseudo named object
is renamed with the real name.  When permanently applied, the second pseudo
named object is deleted.

QRPLOBJ is not involved.  It is used for end user programming only.

When PTF is applied - say a program object is replaced - the old object is
moved to QRPLOBJ.
In this way jobs which were using old program will continue to use it.
Deleting a program when some job is executing instructions from this
program, will cause the job to fail.
This is why PTF process uses QRPLOBJ.
It is safe to clear QRPLOBJ at IPL time, because there are no jobs using
any object from QRPLOBJ.

Earlier in this thread Tom Liotta said that you should be careful what you
remove from QRPLOBJ - very true.

Neil,

Are you saying that the objects needed for RMVPTF are stored in QRPLOBJ? If
so I don't believe that is correct for two reasons.

First, if you look very early in the SCPF job joblog you'll see message
CPC2199 from QLICLLIB stating that "Library QRPLOBJ Cleared." This message
is from the CLRLIB command (well, ok from the CPP). I doubt the CLRLIB
command skips the PTF objects in QRPLOBJ. Secondly, I believe all PTF
objects are renamed to QPZA* in QSYS, take a look, you probably have a ton
of them.

What you are seeing are the objects that would be used if you ran
RMVPTF.
As you are permanently applying the PTF's these objects are no longer
needed, and can be cleared.

I would definitely agree with this statement Tom.

With my perm applying PTF's to free up disk space and prep for an OS
upgrade, I saw MANY PTF related objects created in QRPLOBJ and I would
be
very leery of blowing these away...

I had never noticed this in QRPLOBJ before but had noticed the usual
program
or display file objects due to compiling stuff in use at the time...

JMHO,

Chuck

trouble. Objects should not be removed from QRPLOBJ unless you know what
they are. The system does some of its own work through this library and
can
be disrupted if some of its objects disappear.

On most days at most sites, there's probably no problem. But blanket
CLRLIB
should be avoided.
