Error description

  • If tracing is enabled for class
    com.ibm.ws.portletcontainer.core.impl.PortletRequestImpl a

    com.ibm.ws.portletcontainer.util.StringUtils
    .convertMapToString if you are working with the administrative
    console.
    

Local fix

  • Workaround provided:
    1. Log into the Tivoli Integrated Portal console. For TIP 2.x
    releases, after logging in navigate to Settings > Websphere
    Administrative Console. (If portlet error appers, login via
    port
    16316 i.e. http://hostname:16316/ibm/console)
    2. Navigate to Troubleshooting -> Logs & Trace
    3. Click on the Server1 -> Select Diagnostic Trace Service.
    Increase the Maximum Number of Historical Files from 1 to 10.
    4. Click Apply, then select Change Log Detail Levels.
    5. Click on Runtime tab to enable tracing for the TIP process
    that is currently running. Enabling tracing from the Runtime
    tab
    will keep tracing active until the next time the TIP server
    process is stopped. To make tracing persistent even after
    stopping and restarting the TIP server process click the
    Configuration tab instead.
    6. Clear the trace string in the Groups box and replace it with
    the following:
    
    *=info: com.ibm.isc.*=all: com.ibm.isclite.*=all:
    com.ibm.iscportal.*=all
    
    NOTE: In the customer tipv2 files that I restored, the setting
    of this is *=info: com.ibm.ws.*=all
    
    7. Click  on the Apply button.
    
    8. Restart the TIP server
    
    9. Login to TIP and test Roles
