Issue/Introduction
Using CAIENF to propagate modifications between Top Secret on several partitions.
Some weeks ago,changing the parameters of CAIENF to be able to use TCPIP/TLS and not SNA.
First, just adding the necessary to be able to use TCPIP, but now still using SNA and not yet TCPIP.
Experimenting a very high CPU consumption since this evolution, in the CAENF STC.
Environment
COMMON SERVICES 15.0 - z/OS supported releases -
Resolution
The "listen" that is built incorrectly is listening for ENFTERM, JOBTERM, and JOBFAIL events. However, JOBFAIL is set as inactive.
So update the ENF parameters:
change:
EVENT(JOBFAIL,INACT)
to
EVENT(JOBFAIL,ACT)
and recycle ENF.
There is no command to see the length of the event queue, but if a dump is generated, the environment can be checked to look as expected.
Review of the dump provided shows there isn't a buildup of unprocessed events.
