Error description
Environment: TEPS on Linux/AIX, all releases Problem Description: After running 'itmcmd config -A cq' on Linux or AIX, upon restarting the TEPS it consumes high CPU. Restarting the TEPS may or may not resolve the problem. TEPS is configured to use SSL for client/server communication and during the reconfigure step, clients are left running. The clients do not reconnect after the TEPS is restarted. Detailed Recreation Procedure: 1. Configure TEPS to use SSL 2. Start a client 3. Stop the TEPS, but leave the client running 4. Run 'itmcmd config -A cq' 5. When the config process ends, restart TEPS == Approver: MP

Problem summary
During a portal server reconfiguration, the server starts in a reduced functionality mode which does not support client connections. However it will write out a new IOR file, and if any clients are attempting to reconnect, they will get this new IOR and start trying to connect on the address and port identified in the IOR string. This IOR string also does not enable SSL, so the clients will not use SSL in their connection attempts. If SSL is configured for use in normal production mode, when the portal server restarts, it will start rejecting non-SSL connection attempts. Due to an issue with the CORBA client code, the clients will never become aware of the new IOR file written after the portal server restarts, and will continue trying to connect without using SSL. These repeated connection attempts cause the portal server to use high CPU.
Problem conclusion
During a portal server reconfigure operation, force the portal server to bind to the localhost interface only, and do not specify a port. The fix for this APAR is contained in the following maintenance packages: | interim fix | 6.2.0.3-TIV-ITM-IF0001
Temporary fix
Edit cq/original/lnxnocmsenv and delete the following lines: KFW_INTERFACE_cnps_PORT=15001 KFW_INTERFACE_cnps_SSL=N Add the following line: KFW_INTERFACE_cnps_HOST=localhost
