30 Oracle User Messaging Service

30.1.1 Permission Grants for Upgraded Domains

In order for Oracle User Messaging Service to run as a specific user, a code-based permission grant is required. This grant is pre-seeded in WebLogic domains that are created after the Fusion Middleware 11gR1 Patch Set 2 upgrade.

If you created a WebLogic domain prior to the Patch Set 2 upgrade, you must manually add this grant by running the following Oracle Platform Security Services (OPSS) WLST commands in online (connected) mode:

 wls:/mydomain/serverConfig>
grantPermission(codeBaseURL="file:${ums.oracle.home}/communications/modules/oracle.sdp.client_11.1.1/-",
permClass="oracle.security.jps.JpsPermission",permTarget="IdentityAssertion", permActions="execute")

 wls:/mydomain/serverConfig>
grantPermission(codeBaseURL="file:${ums.oracle.home}/communications/modules/oracle.sdp.messaging_11.1.1/-",
permClass="oracle.security.jps.JpsPermission",permTarget="IdentityAssertion", permActions="execute")

See Oracle WebLogic Fusion Middleware Scripting Tool Command Reference for information regarding grantPermission

30.1.2 XML File Handle Left Open after Upload Fails

If an error occurs when uploading a user messaging preferences XML file using the WLST manageUserMessagingPrefs command, the XML file handle is left open. On the Microsoft Windows platform, this file cannot be deleted until you exit the WLST shell.

30.1.3 Messages Metrics Rendered as Unavailable in the Performance Page for User Messaging Server

When no metric data is found, for example when no messages have been sent or received after server setup, the Metrics Performance page will display Unavailable. This is not a problem with the software, and the Performance reporting is operating properly. As soon as Send and Receive traffic exists, the Performance page will display results normally.

30.1.4 User Messaging Service URLs Unavailable After Restart

Upon restarting the User Messaging Service server (usermessagingserver) from Oracle Enterprise Manager Fusion Middleware Control or through Oracle WebLogic Console, you may get an error: Error 503--Service Unavailable when attempting to access any URLs served by the User Messaging Service server, such as the User Preferences UI (/sdpmessaging/userprefs-ui) or the various Web Services endpoints. This error occurs intermittently in cases when the Oracle WebLogic Server is heavily loaded (such as with a SOA instance). To work around this issue:

• Restart the User Messaging Service server again (two or more restarts may be required).

• If multiple User Messaging Service server restarts are not sufficient, then restart the entire Oracle WebLogic Server instance.

30.1.5 User Preferences User Interface Renders Improperly

Intermittent UI rendering errors have been reported in some languages, due to the generation of a corrupted .css file. If you experience problems, follow these steps to work around the issue:

1. Delete the cached, auto-generated .css file for the affected locale (or simply, all locales) on the server located at DOMAIN_HOME/servers/<server_name>/tmp/_WL_user/usermessagingserver/<random_name>/public/adf/styles/cache and restart the usermessagingserver application using Oracle Enterprise Manager Fusion Middleware Control. Have all users clear their browser caches.

   The next time the UI is accessed from a browser, a new .css file will be generated for the desired locale, and it is very likely that it will be a valid .css file. If not, repeat this process a couple of times.

2. If the previous solution does not work, disable content compression in the web.xml file of the User Preferences Web Module located at DOMAIN_HOME/servers/<server_name>/tmp/_WL_user/usermessagingserver/<random_name>/sdpmessaginguserprefs-ui-web.war. In particular, extract web.xml, add the following <context-param/> to it:

   <context-param>
     <param-name>org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION</param-name>
     <param-value>true</param-value>
   </context-param>
   

   Then, re-archive it to the war module.

   Finally, restart the usermessagingserver application using Oracle Enterprise Manager Fusion Middleware Control.

30.2.1 Reconfigure Drivers After PS2 Patch

After installing the PS2 patch, you must manually reconfigure your drivers, using Oracle Enterprise Manager Fusion Middleware Control. You can retrieve a backup file of your previous driver configuration at: $DOMAIN_HOME/config/fmwconfig/servers/<ServerName>/applications/<DriverName>/configuration/driverconfig.xml.bak

Restart your servers after making any changes!

30.2.2 Migrate Custom Business Terms After PS2 Patch

After installing the PS2 patch, you must re-create any custom-built business terms using Oracle Enterprise Manager Fusion Middleware Control. A copy of the custom-built business terms is available at: $DOMAIN_HOME/config/fmwconfig/servers/<ServerName>/applications/usermessagingserver/configuration/businessterms.xml.bak

Restart your servers after making any changes!

30.2.3 Use Correct SSL Trust Store When Configuring Drivers

Before configuring any User Messaging Service Driver (such as the Email Driver) to connect to a remote gateway using SSL, ensure that the correct SSL Trust Store is used:

Update the value of the JVM system property (javax.net.ssl.trustStore) set in $DOMAIN_HOME/bin/setDomainEnv.sh (or Windows equivalent).

30.2.4 User Messaging Service Driver Configuration Changes Not Immediately Effective

When you change a driver's configuration and then restart the driver, the changes will not take effect until all managed connections in the pool are destroyed (900 seconds [15 minutes] by default). Take one of these actions to ensure that the connections are destroyed:

• When performing driver configuration changes, stop the driver application and wait for 15 minutes. Then re-start the driver application.

  Note:

  If you follow this recommendation and the wait time of 900 seconds (15 minutes) is too long, you can reduce the time using the Oracle WebLogic Server Administration Console as follows:

  1. Click Deployments.

  2. Select the desired User Messaging Service Driver deployment.

  3. Click the Resource Adapter Type module.

  4. Click Configuration > Outbound Connection Pools.

  5. Click the DriverConnectionFactory group.

  6. Click Connection Pool.

  7. Edit the value of Shrink Frequency Seconds (for example, set to 120 seconds).

  8. Click Save, and save the changes to a deployment plan file when prompted.

  9. Restart the User Messaging Service driver deployment to include the new plan.

  Remember that if Shrink Frequency is reduced to a short interval, it may eventually have a negative impact on the performance of the driver as idle connections will be recycled frequently.

  OR

• Restart the entire Oracle WebLogic Server after performing driver configuration changes. The new changes will take effect immediately upon server re-start.

30.2.5 Email Notifications Sent Even if You Do Not Change Default Parameters in driverconfig.xml

Instructions for notification configuration include setting your outgoing server parameters. Please note that if you do not change the parameters (that is, if you leave the default setting unchanged), notifications may still be sent. This is expected behavior, but you should not rely on the default settings without verifying them. You should set your parameters to ensure that they are correct.
