Troubleshooting UCMDB Browser - Known Issues

ClosedProblem: "There is no data available for this report" message is displayed for individual default report widgets (such as Installed Software) on UCMDB Home

  • Cause: It could be one of the following:

    • It is true that there is no data available for the reports. Or,
    • The reports are querying over a large amount of data from the UCMDB server which exceeds the maximum number of elements allowed in view, and you may find "server view query over limit" error in log.
  • Solution: In case of the second scenario, to resolve the display issue, go to UCMDB UI > Administration > Infrastructure Settings Manager, locate the Maximum number of elements (nodes) in TQL result for view setting (default value: 30000) and increase its value to meet your need.
ClosedProblem: Performance for the UCMDB Browser is slow.

  • Possible Solution: Add the variable CATALINA_OPTS to the Operating Systems environment variables with values:

    -Xms512M -Xmx4096M

ClosedProblem: The Tomcat log that contains requests to the UCMDB Browser and their HTTPS codes becomes too large and is unreadable.

  • Solution: Comment out the following lines in the server.xml file, located in <UCMDB_Browser_installation_directory>\webapps\release\conf:

    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
    prefix="localhost_access_log." suffix=".txt"
    pattern="%h %l %u %t &quot;%r&quot; %s %b" />
ClosedProblem: Icons are not displayed when the Turn Off Data URI support setting is not disabled.

  • Solution: Disable the Turn Off Data URI support setting on Windows as follows:

    1. Click Start, type gpedit.msc in the Start Search box, and then press ENTER.
    2. In the navigation pane of the Local Group Policy Editor window, expand Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Security Features.
    3. In the right pane, double-click Turn Off Data URI support.
    4. Select Enabled, click Apply, and then click OK.
    5. Go back to the navigation pane of the Local Group Policy Editor window, expand User Configuration > Administrative Templates > Windows Components > Internet Explorer > Security Features.
