Error description

  • When 'EMHL=,' is specified in DFSPBxxx, the first DFS1929I
during IMS initialization showed 'EMHL=0' correctly. But the
second DFS1929I during IMS restart processing showed 'EMHL=512'
incorrectly.
This is an error in DFSSDSP0.
DFSSDSP0 is using ESCDEMHL. But it is not correct.
ESCDEMHL is the largest EMHB size and it is not EMHL value.
For EMHL, we should use SCDEMHBL.

****************************************************************
When the length of the Fast Path expedited message handler
buffer (EMHL) is specified as 'EMHL=,' in DFSPBxxx, the first
DFS1929I during IMS initialization showed 'EMHL=0' correctly.
But the second DFS1929I during IMS restart processing showed
incorrect value of EMHL.

Module DFSSDSP0 uses ESCDEMHL for EMHL value. ESCDEMHL is
the largest EMHB size and it is not EMHL value.

    



Problem conclusion


    

  • AIDS: RIDS/FP RIDS/CNTRL FP CNTRL
 GEN:
KEYWORDS:

*** END IMS KEYWORDS ***
Module DFSSDSP0 will be modified to use SCDEMHBL for the value
of EMHL.
