Hello readers,
I know it has been a while since I posted anything here. I have been busy. Just thought I would pop by and enter another little note.
On a client site I was having some sporadic connection issues between the portal, SRM, SUS, ECC, PI, etc. All configuration and system settings seemed to be correct, however after several minutes of moderate use (or several hours of light use) things would stop working. The UWL would begin throwing "credential" issues, the SSO connection tests would begin to give error, and iViews stopped providing information from the backend.
After some digging I found the following line in the Java logs in multiple locations:
"Max number of 100 conversations exceeded..."
Then it hit me.
So I went to the server and made sure to check for the CPIC_MAX_CONV system environment variable in windows. Sure enough, it was not set. Thus the system was stopping CPIC connections at 100 (the default).
After setting CPIC_MAX_CONV to 2000, and restarting the SAP system all these sporadic errors went away.
Just an FYI, this is something that should be set at initial install, and as observed it can cause many strange communication errors if it is not set.
Hope this helps...
Joey
