44.9 Troubleshooting Common Errors

You might encounter the following error when you redeploy the identity applications:

11:32:20,194 ERROR [[PortalAggregator]] Servlet.service() for servlet
PortalAggregator threw exception java.lang.OutOfMemoryError: PermGen space 

To avoid this error, either:

or

If your email notification templates are displaying in a single language and not in the user’s default locale as you expect, check to see what notification template is selected. You can select a default template or a localized version of the template. When you select a localized template, the language of the localized template is used regardless of the user’s default language. When you select the default template (the template without a locale code), the email is in the user’s default language (if the default is a supported language).

If you encounter an error like this at runtime, then you must modify the service definitions in the User Application WAR:

error: "an error occurred Control instantiation of JUICE.OrgChartCtrl failed (Object doesn't support this property or method). Please contact your system administrator. Detailed information can be found in the console." when accessing the portlet in a browser.

If the Notify Other Users of these Changes check box does not display on the following pages:

Verify that Email Notification templates have been defined. You define them through the Administration > RBPM Provisioning and Security > Delegation and Proxy.

If you encounter a javax.naming.SizeLimitExceededException when you use the Administration > Page Admin > Set As Default, you might have encountered a maximum size limit. You can modify this limit in the PortalGroupPageDefaults portlet settings in the portlet.xml as follows:

<portlet>
    <portlet-name>PortalGroupPageDefaults</portlet-name>
   <portlet-class>
com.novell.afw.portal.portlet.core.permission.PortalGroupPageDefaults
</portlet-class>
    <init-param>
      <name>MIN_CACHE_SIZE</name>
      <value>20</value>
    </init-param>
    <init-param>
      <name>MAX_CACHE_SIZE</name>
      <value>200</value>
    </init-param>
    <init-param>
      <name>PAC_MAX_RESULTS</name>
      <value>2000</value>
    </init-param>
    ...
</portlet>

If you have more than 200 groups and want to assign groups to the View permissions for the Page Admin tab, you also need to update the settings for the PortalUserGroupSelection portlet. Modify this limit in the portlet.xml as follows:

<portlet>
    <portlet-name>PortalUserGroupSelection</portlet-name>
   <portlet-class>
com.novell.afw.portal.portlet.core.permission.PortalUserGroupSelection
</portlet-class>
    <init-param>
      <name>MIN_CACHE_SIZE</name>
      <value>20</value>
    </init-param>
    <init-param>
      <name>MAX_CACHE_SIZE</name>
      <value>200</value>
    </init-param>
    <init-param>
      <name>PAC_MAX_RESULTS</name>
      <value>2000</value>
    </init-param>
    ...
</portlet>

Redeploy the identity applications after you make your changes.

If you run the User Application on Linux, you might encounter a Too Many Open Files Error.Linux allows 1024 open files for each process, but the identity applications often requires more. NetIQ suggests increasing the number of open files to 4096 to avoid the Too Many Open Files error.

Use the ulimit command to increase the number of open files. There are some restrictions on ulimit for non-root users. Here is an example of how you can use the ulimit command to increase the number of open files to 4096 for a non-root user:

You might want to specify ulimit in the user environment or the start-tomcat script so that the new value is always used.
