Issue:
Following a level set upgrade on our MainFrames, we had various CCI disconnect issues with UUJMA and over 50 jobs were outstanding with a status of 7UWT.

CCI becomes unresponsive when multiple machines in its configuration file becomes unreachable. 
 
Environment:
Several  MainFrame machines running CA-7  connected to multiple  UUJMA servers on  Linux, Aix and Solaris 10 machines

UUJMA release 11.2 SP2 CUM1



 
Cause:
CCI makes connection attempt against inactive machines once every 90 seconds.
A timeout from an offline machine may take anywhere between 15 to 30 seconds based on the
settings.
CCI being a single threaded application, these connection attempts are serial.
A handful of offline machines take more than 90 seconds in total to process.
Thus, CCI remains stuck awaiting connections from offline machines and responds to requests only once every few
minutes. 
Resolution:
Problem fixed by these patches which are available at http://support.ca.com
