APAR Error Description / Circumvention

-------------------------------------------------
A system is trying to create spooled files under a QPRTJOB for a
particular user. However, any attempt at such a creation (for
example, by using SNDNETSPLF or SNDTCPSPLF) will loop. There
appears to be contention on the Spool Control Block for the
QPRTJOB.

CORRECTION FOR APAR 'SE52777' :
-------------------------------
The SCB (Spool Control Block) for that user's active QPRTJOB was
detached with the command CHGJOB SPLFACTN(*DETACH) and the
detach never finished -- perhaps the job doing the detach was
ended because it was taking too long.  While the detach is in
progress, program QSPOPEN would loop, waiting for the detach to
complete.  When the system was IPL'ed, the Spool Initialization
step finished detaching the SCB, so QSPOPEN was able to create a
new QPRTJOB and continue past the loop.
QSPOPEN will now create a new QPRTJOB immediately when it
detects that the old one's SCB is being detached, instead of
waiting for the detach to complete and then creating a new
QPRTJOB.

CIRCUMVENTION FOR APAR 'SE52777' :
----------------------------------
Do not detach a QPRTJOB that is actively being used to create
new spooled files.


Activation Instructions


None.




Special Instructions

Before applying or removing this PTF in immediate mode (without an IPL)
you should end all writers or end the QSPL subsystem.  The PTF will be
active when the writers are restarted.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
