When IDMS is re-started after a unclean shutdown, the following error may be encountered:-
17.53.35 JOB00305 +IDMS DC075110 VTAM FUNCTION OPEN ACB ERROR CODE = 0070000 APPLID = .IDMSG2
It may be necessary to recycle VTAM to resolve this.
Release : All supported releases.
Component : CA IDMS
The RC=0070 is a VTAM return code and the meaning is:
"You attempted to open an ACB that is in the process of being closed.
This can occur when a VTAM application program job step or subtask is cancelled or terminates abnormally.
The process of closing the ACB may continue after the job step or subtask has actually terminated.
Subsequently if the job step is restarted or the subtask reattached before the ACB closing process has been completed, an OPEN macro instruction that is then issued for that ACB will fail."
So IDMS has been cancelled (or otherwise abended) and re-started, and VTAM is still in the process of closing the ACB.
Try VARYing the NODE INACTIVE/ACTIVE in VTAM and then (if possible) VARYing the LINE OFFLINE and ONLINE in IDMS (from a UCF line if necessary).
If this is not successful, VTAM must be re-cycled.
Any other solutions must be pursued with IBM regarding why VTAM was taking so long to close the ACB.
