|Oracle® Fusion Middleware Release Notes
11g Release 1 (11.1.1) for HP-UX Itanium
Part Number E14773-11
This chapter describes issues associated with Oracle WebCenter. It includes the following topic:
This section describes general issue and workarounds. It includes the following topics:
Oracle WebLogic Communications Server (OWLCS) is provided as a sample for development only. It should not be used for production deployments.
Oracle WebCenter Discussions (Jive Forums) is an optional component of Oracle WebCenter. Complete documentation for Jive Forums is included for reference. However, Jive software installations and upgrades outside of the WebCenter product installation are not supported.
At runtime, if you encounter a null pointer exception while trying to customize or refresh the content of a Rich Text Portlet, reload the page, and then customize or refresh your portlet.
Upon selecting a link in a WebCenter Spaces application, the active cursor does not automatically move to the content area in new non-popup/popover pages that are launched. To work around this issue, you can manually tab over to the new content area.
When using only the keyboard in WebCenter Spaces, you cannot move a favorite into an existing folder. To work around this issue, create a new, duplicate favorite within the existing folder, then delete the original favorite that exists outside the folder.
When using only the keyboard in WebCenter Spaces, you cannot select a date from the date picker in the Message Board tab and the Feedback tab of your personal profile. To work around this issue, instead of using the date picker, type the date into the required field.
When using only the keyboard in WebCenter Spaces, you cannot expand or collapse folders in the All Saved Searches task flow. To work around this issue, view the saved searches using the Search main view task flow for personal saved searches, or the Search group main view task flow for group space-specific saved searches.
When you click the RSS icon in a WebCenter Spaces application, if SSO is not configured, a Login dialog prompts for your user name and password. The user name that you enter must contain only ASCII characters.
After you migrate from Oracle WebCenter 126.96.36.199.0 to Oracle WebCenter 188.8.131.52.0, you may initially see a group space GUID in Activity Stream in lieu of a group space name in WebCenter Spaces. This can occur when you configure an Activity Stream task flow instance and select to display activity from a group space that was migrated. You can work around this issue by generating some activity in that group space, like adding or removing a member. This refreshes the Activity Stream instance with the group space display name.
In JDeveloper, choosing Clean Runtime MDS Customizations from the Application menu does not clear customizations made at runtime that are stored in the MetaData Services (MDS). You can delete customizations by either manually deleting them from the configured directory or by using JDeveloper.
To clear these customizations by using JDeveloper:
In the Application Navigator, click the Application Menu icon next to your application's name and select Application Properties.
In the Application Properties dialog, expand the Run node in the left pane, then select MDS.
In the right pane, under Run: MDS, select Delete customizations before each run. Doing so clears the MDS of any runtime customizations every time you run the application. To save the runtime customizations every time you run the application, select Preserve customizations across application runs.
In WebCenter Spaces, profile settings set on the WebCenter Administration > Services > Profile screen are not retained when you upgrade from Oracle WebCenter 184.108.40.206.0 to Oracle WebCenter 220.127.116.11.0. After the upgrade, a WebCenter administrator must reapply the required profile settings on the WebCenter Administration > Services > People Connections > Profiles screen.
At runtime or when you deploy a custom WebCenter application to a Managed Server, diagnostic logs may report exceptions similar to the one listed below. Such exceptions do not impact application functionality, and can be ignored.
[2009-11-01T23:18:37.160-08:00] [CustomAppServer] [ERROR]  [oracle.webcenter.concurrent.Submission] [tid: pool-1-daemon-thread-7] [userId: Lisa] [ecid: 0000IInkaNCDsXlfwtq2T01AvcNC000013,0:3] [APP:TutorialApp#V2.0]caught exception removing thread context
When using only the keyboard in WebCenter Spaces in Internet Explorer 7, cursor position is not highlighted for certain buttons in the Documents tab and the Document List Viewer task flow in page edit mode. Although the cursor position indicator is not shown, the cursor focus for the button objects is correct. To work around this issue, use Internet Explorer 8 or any other supported browser like Safari 4.x or Firefox 3.x.
If the Oracle WebCenter instance is running in a native encoding, when you try to add content to a page based on the Text Page template in WebCenter Spaces, you may encounter a metadata repository error due to incorrect character length calculation. This error occurs when the calculated character length is less than or equal to 4000 bytes but the actual occupied bytes is more than 4000.
To work around this error, set the environment variable
utf-8 on the server on which Oracle WebCenter is deployed.
When you create a group space, an error similar to the following might be seen if provisioning a service exceeds the time allowed:
Group space created with the following warnings:
Issues were faced while provisioning the services. Errors were encountered for the following services - Discussions and Announcements. Check if these services have been configured correctly.
When a group space is created, services are provisioned in parallel in multiple threads. If provisioning a service exceeds the specified timeout, the thread is interrupted. The timeout may be exceeded due to time needed to copy the metadata when the latency between the midtier and the database is too high, network issues, database performance issues, and so on.
To check if the issue is due to exceeding the timeout, search the log file for a message similar to the following:
<Nov 3, 2009 4:44:06 PM GMT> <Warning> <oracle.webcenter.webcenterapp> <BEA-000000> <Concurr: The thread is timed out in 10000 milisec. for oracle.webcenter.collab.forum:Execution timedout queued : 12 ms suspended : 0 ms running : 5842 ms timeout : 5000 ms service : oracle.webcenter.community resource : oracle.webcenter.collab.forum source : oracle.webcenter.concurrent.RunnableTask@23268a92 (oracle.webcenter.concurrent.RunnableTask) submission : 15> <Nov 3, 2009 4:44:06 PM GMT> <Warning> <oracle.webcenter.webcenterapp> <BEA-000000> <Concurr: The thread is timed out in 5000 milisec. for oracle.webcenter.collab.announcement:Execution timedout queued : 37 ms suspended : 0 ms running : 5875 ms timeout : 5000 ms service : oracle.webcenter.community resource : oracle.webcenter.collab.announcement source : oracle.webcenter.concurrent.RunnableTask@37538945 (oracle.webcenter.concurrent.RunnableTask) submission : 18> <Nov 3, 2009 4:44:06 PM GMT> <Warning> <oracle.webcenter.collab.forum.internal.jive.CategoryTaxanomyCreator> <BEA-000000> <java.io.InterruptedIOException: Operation interrupted
In this case, the running time of 5875 ms exceeded the timeout of 5000 ms. The root cause of the timeout should be addressed; for example, resolve networking or database performance issues.
The networking issues could be resolved by incresing the TCP/IP timeout value.To change the timeout values, log in as a
root user and execute the following command:
ndd -set /dev/tcp tcp_time_wait_interval 480000 (default value is 60000)
Restart the Administration and Managed Servers. Once this is done, the group space can be created again and the error will not be encountered. If the performance cannot be improved and the error persists, the timeout value may be increased for the service encountering the error. For more information, see Section A.5.5, "Configuring Concurrency Management."
When you define a connection for the Discussions or Announcements service you must always enable WS-Security and configure the associated keystore/encryption details. WS-Security is not optional as documented in the online help.
To enable WS-Security on discussions server connections:
Fusion Middleware Control: Select the Connection Secured checkbox
true in the WLST commands
To configure WS-Security properties, specify:
To upload multiple files to a group space or personal space, you can use WebDAV or the Oracle Content Server Batch Loader utility:
Go to the Document Manager task flow on a page or go to the Documents page (in a personal space or group space) where you want to upload files.
If desired, create a new folder for the documents you plan to upload. In the Create Folder dialog, make note of the root folder path specified by Create Folder In.
Note:The root folder where your group space is stored in Oracle Content Server is
Choose either of the following methods for uploading files to the group space or personal space folder:
To use WebDAV, which is installed with Oracle Content Server out-of-the-box, refer to "Importing Documents for a Group Space" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter.
To use the Batch Loader utility, refer to the "Batchloading Content" chapter in Managing System Settings and Processes, available at
