PK51159: TWO S0C4 ABENDS IN METHOD EYU0XLML WHEN THE COLU TRANSACTION IS ISSUED WITH THE QUE ALL OPERANDS.

Error description

The COLU QUE ALL command lists out all allocated queues, along
with the method that allocated them. To determine the allocating
method, it looks at data created at allocation time, based
partially on parms passed in by the allocator. Method XDJI,
which allocates a couple of queues for the API, passes in
invalid data when it does the allocates. This causes the two
abends, one for each of the queues. This would happen regardless
of the load on your dataspaces.

****************************************************************
When the COLU transaction is issued with the QUE ALL operands,
method EYU0XQQQ (XQQQ) is called to list all allocated queues.
For each queue, XQQQ calls method EYU0XLML (XLML) to determine
the method name.  XQQQ passes information provided by the method
that allocated the queue, which XLML uses to identify that
method.  If the data provided by the allocating method is
invalid, XLML may abend when trying to process it.

Method EYU0XDJI (XDJI) allocates two queues during CMAS
initialization for API processing.  XDJI provides invalid
identification information when it calls method EYU0XQCQ (XQCQ)
to allocate the queues.  This results in the abends that occur
when the COLU transaction is issued with the QUE ALL operands.

Problem conclusion

XLML has been updated to recognize if the allocation method
identification is invalid when called by XQQQ.  XLML will return
an invalid method name response to XQQQ, instead of abending.
XDJI has been updated to provide proper identification to XQCQ
when called to allocate queues during CMAS initialization.

Comments

Multiple abend ASRA S0C4 will occur in
method EYU0XLML (XLML) when the COLU
transaction is issued with the QUE ALL
operands.

The call back trace displayed by
message EYUXL0905E will be as follows:

  Methods=XLML,XQQQ,XL70,XLUT,XLOP

Note that since the transaction can be
issued from either a CMAS or MAS, the
abend can occur in either a CMAS or
MAS.
