|Oracle® Fusion Middleware Release Notes
11g Release 1 (11.1.1) for Linux x86
Part Number E10133-05
This chapter describes issues associated with Oracle User Messaging Service. It includes the following topics:
This section describes general issue and workarounds. It includes the following topic:
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.
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.
Upon restarting the UMS 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 UMS 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 UMS server again (two or more restarts may be required).
If multiple UMS server restarts are not sufficient, then restart the entire Oracle WebLogic Server instance.
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:
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.
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.
This section describes configuration issues and their workarounds. It includes the following topics:
In a clustered (high-availability) environment with Oracle HTTP Server (OHS) configured, do not use the OHS port to configure the VoiceXML Driver Receive URLs. Using the OHS port to configure the VoiceXML Driver Receive URLs will cause a conflict with the drivers.
Each Voice XML Driver must be configured with its own WLS server's port (as described in the parameters' documentation).
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:
Select the desired UMS Driver deployment.
Click the Resource Adapter Type module.
Click Configuration > Outbound Connection Pools.
Click the DriverConnectionFactory group.
Click Connection Pool.
Edit the value of Shrink Frequency Seconds (for example, set to 120 seconds).
Click Save, and save the changes to a deployment plan file when prompted.
Restart the UMS 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.
Restart the entire Oracle WebLogic Server after performing driver configuration changes. The new changes will take effect immediately upon server re-start.
UMS and Oracle Fusion Middleware use Sun's JavaMail (
http://java.sun.com/products/javamail/) for various mail and messaging operations. JavaMail is used extensively in the UMS email driver, as well as in Oracle Fusion Middleware Webservices (including the UMS Parlay X API) to handle MIME-encoded content.Oracle Fusion Middleware Release 11gR1 includes JavaMail version 1.4. This version of JavaMail has a bug that may cause multipart web service content (SOAP attachments) larger than 8kb to be truncated. This behavior will occur when using the UMS Parlay X SendMessage interface; if the message content is a multipart object, the content beyond 8kb may either be truncated silently, or the operation may fail if the truncation causes a decoding failure.This issue is resolved in JavaMail version 1.4.1. In order for the new JavaMail library to take effect, it must be made available in the Oracle WebLogic Server system classpath so it is available to the web service infrastructure.
To accomplish this, use the
PATCH_CLASSPATH environment variable. Libraries and directories listed in this classpath are prepended to the system classloader's classpath. You can either set this environment variable manually in your environment each time you start a server where UMS is running, or edit
DOMAIN_HOME/bin/setDomainEnv.sh (UNIX) or
DOMAIN_HOME/bin/setDomainEnv.cmd (Windows), updating the line where
PATCH_CLASSPATH is set, making sure to include the path to the JavaMail 1.4.1 library.
This section describes documentation errata. It includes the following topic:
The User Messaging Service documentation (in both the Developer's and Administrator's guides) did not list the location of the User Messaging Preferences UI. The standalone user interface is available at:
The User Messaging Preferences UI is also embedded in the SOA Worklist application. You can access it from the Worklist application by choosing Preferences > Notification.
