PI43437: STC SOT STARTED BY THE STC TAS IS KEEPING AN ENQUEUE ON DL1 DATABASE DURING BTS TESTS USING DAI

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• STC SOT STARTED BY THE STC TAS IS KEEPING AN ENQUEUE ON DL1 DATA
  BASE DURING BTS TESTS USING DAI
  When we try to delete/define the database, the delete is
  rejected because the database is in use :
  IKJ56241I DATA SET BT.IMSVK.FCMDLOG.CLUSTER NOT ALLOCATED
  IKJ56241I DATA SET IS ALLOCATED TO ANOTHER JOB OR USER

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users who execute applications in a          *
  *                 DAI SOT that dynamically allocate            *
  *                 data sets but do not free them.              *
  *                                                              *
  *                 Users who start a DAI server that            *
  *                 attempts to connect to an XCF group          *
  *                 where the server is already active.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: If an application executing in a DAI    *
  *                      SOT dynamically allocates data sets     *
  *                      but does not free them, the data sets   *
  *                      remained allocated in the SOT address   *
  *                      space until the TAS server was          *
  *                      stopped.  An example was seen when BTS  *
  *                      executing in an SOT address space used  *
  *                      IMS services that dynamically allocated *
  *                      IMS databases.  The databases remained  *
  *                      allocated in the SOT after BTS ended.   *
  *                                                              *
  *                      DAI s TAS server controls starting and  *
  *                      stopping SOT address spaces.  If        *
  *                      multiple TAS instances are started in   *
  *                      the same XCF group, they compete for    *
  *                      control of the SOT address spaces.      *
  *                      This resulted in unpredictable          *
  *                      processing.                             *
  ****************************************************************
  * RECOMMENDATION: APPLY the PTF.                               *
  ****************************************************************
  SOT processing will check for allocations left in the address
  space after an application ends.  If residual allocations are
  detected, they will be freed. If the free is not successful,
  the SOT will stop itself and TAS will start a replacement SOT.
  
  Before joining an XCF group, DAI's TCP and TAS servers will
  determine if a server instance is already active in the group.
  When this situation is detected, the starting server will issue
  a duplicate server message (AII2006E) and will stop with
  ABENDU500-14.
  

Problem conclusion

• APPLY the PTF.
