Hi Steve,
The AB/S0878 might be a result of SMF Exits needing re-coding.
Also, if you supply the (subcode e.g. 0C) it would be helpful.

It might also be related to too many active channels in MQ.
Please see:
Why is the IBM MQ Channel Initiator abending with ABEND878? <https://www.ibm.com/support/pages/why-ibm-mq-channel-initiator-abending-abend878>

Regards,
David

We are having a problem.  TcVision is a support product for ADABAS.

A couple times a week the Address Space gets an S878 and falls down.

And the users are getting upset.

Can anyone suggest a way to let the S878 die off and some how

set an ARM to allow ARM to case the TcVision to restart.

PS: I am oceans out of my depth with ARM
