Error description
The TPC 5.2 Web-based GUI -> Storage or Server Resources -> Action then View Data Path can increase CPU usage on AIX to abnormal values. It can be observed by using a resource monitor application on AIX (e.g. nmon) that the process that is assigned to the TPC Web Server is using a large part of CPU. The TPC Web server doesn't release the CPU CPU resources after closing the TPC Web-based GUI. The CPU can only be released when the TPC Web Server process is killed. The following messages can be noticed in the SystemOut.log for the TPC Web server: [11/28/13 10:01:02:410 CET] 0000001d ThreadMonitor W WSVR0605W: Thread "WebContainer : 0" (0000002b) has been active for 645484 milliseconds and may be hung.

Problem conclusion
The fix for this APAR is targeted for the following maintenance package: | refresh pack | 5.2-TIV-TPC-RP0003 - target August 2014 http://www-01.ibm.com/support/docview.wss?&uid=swg21320822 The target dates for future refresh packs or fix packs do not represent a formal commitment by IBM. The dates are subject to change without notice.
Temporary fix
To apply a temporary fix please follow the next steps : 1. Stop the TPC Web Server 2. Backup the following files : a. TPC_INST_DIR/ewas/profiles/WebServerProfile/config/cells/WebServ erCell/applications/WebServer.ear/deployments/WebServer/com.ibm. tivoli.rest.war/WEB-INF/web.xml b. TPC_INST_DIR/ewas/profiles/WebServerProfile/installedApps/WebSer verCell/WebServer.ear/com.ibm.tivoli.rest.war/WEB-INF/web.xml 3. Open the following file and identify the ActiveMQBroker.transportConnectorURIs property and extract the port : a. TPC_INST_DIR/ewas/profiles/WebServerProfile/installedApps/WebSer verCell/WebServer.ear/ActiveMQBroker.properties 4. Edit the web.xml files specified in the step 2 by replacing the following lines with the port identified in step 3 (CORRECT_PORT): <context-param> <param-name>org.apache.activemq.brokerURL</param-name> <param-value>nio://localhost:CORRECT_PORT</param-value> </context-param> <context-param> <param-name>brokerURL</param-name> <param-value>nio://localhost:CORRECT_PORT</param-value> </context-param> 5. Start again the TPC Web Server
