PM07794: DYNAMIC CRITICAL PATH: DEADLINE HANDLING ENHANCEMENT

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• The current product design does not allow users to condition
  late processing to the deadlines of critical jobs
  .
  This APAR will improve and the calculation of critical path by
  considering ONLY the deadline of the critical target job itself.
  For all non-critical predecessors of a critical job, an
  operation-level deadline will be simulated beyond the end of
  the tail plan.  The change will be activated at customer option,
  through a two new parameters to the BATCHOPT initialization
  statement, IGNOREDEADL(YES|NO), and TIMEDEPCHK(YES|NO).
  .
  This APAR creates new messages EQQ3165I, EQQ5010I and EQQ5011I.

  ****************************************************************
  To run with an effective late processing in a critical
  network, users are expected to have, for each job table entry,
  a deadline that comes after (or at the same time) respect
  to the deadline of the critical job. This setting is needed to
  have the latest start times calculated accordingly with what
  is specified for critical jobs.
  .
  In addition, Planned Start Times, used to initialize
  Estimated Start Times for critical job table entries,
  are calculated batch by always referring to Input
  Arrival Times even for operations that are not time dependent.
  

Problem conclusion

Temporary fix

Comments

• Two new parameters have been added to be specified in
  BATCHOPT:
  IGNOREDEADL to automatically move deadlines for any
  not critical and not suppress-if-late operation
  to the CP tail end.
  .
  TIMEDEPCHK to calculate planned start times for operations
  that are not time dependent starting from
  the beginning of the extend/re-plan interval instead
  of starting from Input Arrival Time. In addition, dynamic
  addition of critical job entries has been changed to
  initialize the estimated start times to the current time
  instead of using Input Arrival Times, in case of
  operations that are not time dependent.
