Problem summary


    

  • ****************************************************************
* USERS AFFECTED: All DB2 FOR Z/OS V10 AND V11 customers who   *
*                 have applied apar PI19976.                   *
****************************************************************
* PROBLEM DESCRIPTION: During rollback processing, DB2 follows *
*                      a corrupt section pointer which causes  *
*                      a circular chain (infinite loop).       *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
DB2 keeps a linked list of related cursor sections (i.e declare
cursor, update where current of cursor, etc).  In this case the
pointer to the next related section is self-referencing.
This caused DB2 to go into an infinite loop.

    



Problem conclusion


    

  • DB2 will now inspect the linked list to ensure the pointers are
not self-referencing.
