Gilbert,
Yes it can be a problem. Also for LLA libraries that are frozen, until you F
LLA, REFRESH.

I am concerned with the compression of a load-library with DISP=SHR which
can
cause problems, particularily if it's allocated in CICS or LLA. DDLIST
seems
different from ISPF options
Sorry, I had my search list up. This thread was dealt with months ago...

Hello:
I posted a message a week ago on ISPF-L and received no answer;
hopefully, I'll get a good one here. Here it is:
If I enter HELP on the DDLIST panel, I see this:
C Compress a PDS using the existing allocation.
When I use DDLIST to display allocated data sets, I see most of them
As far as I know all ISPF compress operations are done using IEBCOPY, If so,
IEBCOPY enques on IEWxxx and staw to protect the directory from being
manipulated. It does not protect the directory from read, so if CICS or any
other program that has in storage copy of the PDS directory, can be
As far as I know all ISPF compress operations are done using IEBCOPY
ISPF 3.4 uses SPFCOPY - non-APF.
Unless it's changed in the lasr 10 year.
IEBCOPY has to be APF, and compress doesn't need that.

Are you sure IEBCOPY enques on IEWxxx ? How do you know that ?
Is it written somewhere ? My

IIRC, it was changed over 20 years ago, since TSO/E introduced
its Service Routine, which is called IKJEFTSR.

Compress doesn't need IEBCOPY to be authorised ? Are you sure ?
Not 100%
But, I've compressed without it.
Again, SPFCOPY compresses without APF.

IIRC, SPFCOPY got control un-authorized, but it made itself authorized prior to
calling IEBCOPY, but that was very long ago.

Not sure, but LMCOMP is also an option to compress a PDS. But according to
the manual it call IEBCOPY.
