16 Oracle WebLogic Communication Services

This chapter describes issues associated with Oracle WebLogic Communication Services (OWLCS). It includes the following topics:

16.1 General Issues and Workarounds

This section describes general issue and workarounds. It includes the following topics:

16.1.1 Active SIP Session and APP Session Count Show as -1 in Clustered Configuration

In the Administration Console, the Monitoring -> General tab displays Undefined for the Active SIP Session Count and Active Application Session Count attributes when monitoring a replicated WebLogic SIP Server deployment. There is currently no workaround for this problem.

16.1.2 Oracle WebLogic Server Pack/Unpack Tool Does Not Function in OWLCS

The Pack/Unpack tool in Oracle WebLogic Server does not work in this OWLCS release. There is no workaround currently available.

16.1.3 Oracle WebLogic Server Cloning Tool Does Not Function in OWLCS

The Cloning tool in Oracle WebLogic Server does not work in this OWLCS release. There is no workaround currently available.

16.1.4 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.

16.2 Configuration Issues and Workarounds

This section describes configuration issues and their workarounds. It includes the following topics:

16.2.1 Launch_sash Option Error

An error has been reported when using the launch_sash command with the -e option. For example:

MW_HOME/user_projects/domains/base_domain/bin/launch_sash.sh -p 8001 -n weblogic -w welcome1 -a presenceapplication -e "xcap appusage list"

does not properly process the xcap appusage list argument because the double quote (") is mishandled.

To work around this problem, issue the command at the sash prompt directly.

16.2.2 Same User Who Installed WLS/WLSS Product Must Perform Uninstall

In order to perform a clean uninstall, ensure that the same user (privileges) who accomplished the install also accomplishes the uninstall.

16.2.3 Uppercase Usernames Cause Reregistration and Presence Subscription Failures

When a user is created with an uppercase username, then the following occurs:

  • Initial registration progresses normally, resulting in successful registration with Oracle Communicator.

  • Presence subscriptions fails.

  • After a few minutes, Oracle Communicator displays Server Refused Registration (403).

  • User's account is locked and sign-in is blocked for 30 minutes.

To work around this issue, set Trusted Authentication Hosts for the SIP Container by doing the following (from the Administration Console):

  1. Click SipServer in the left pane.

  2. Click the SIP Security tab.

  3. In Trusted Authentication Hosts, add the IP address of your server (that is running OWLCS).

  4. Save and restart OWLCS.


    Using this workaround, presence functionality will fail for clients running on the same machine as the OWLCS server. Such cases (both Oracle Communicator and server running on the same machine) are mostly for demonstration and development environments. For these cases, ensure you create users with lowercase usernames.

Reregistration and presence subscription failures can also occur when users are created with privateId being different than the username part of the publicId.

For example, if privateId is test.user1 and publicId is sip:test.user1@example.com, everything works because test.user1 is the username part of the publicId sip:test.user1@example.com.

But if privateId is tuser1 and publicId is sip:test.user1@example.com, the username part of the publicId is not the same as privateId. In this case, the first registration succeeds with Oracle Communicator, but reregistrations and presence subscriptions fail. Apply the same workaround (configure trusted host as described above) to resolve this issue.

16.2.4 Running the uninstall.sh Script in Text Mode Does Not Uninstall the Product

Perform uninstallation using the Administration Console to ensure that all components are uninstalled. Ensure that you use the same user privilege as when you installed.

16.2.5 SIP Monitor in F5 Networks BigIP Does Not Work in UDP Mode

When using the F5 Networks BigIP load balancer for a cluster of SIP engines and the SIP monitor in BigIP is used for failure detection, it must be configured to operate (sending OPTIONS requests) over TCP and not UDP. UDP mode will not work (the pool will indicate that the servers are down).

16.2.6 SIP Container Does Not Bind to IPV6 Interfaces for Listening on Windows

Due to limitations in the Windows IPv6 stack, the SIP Container cannot bind to IPv6 sockets for listening.

16.2.7 JAWS Unable to Read Some Install Screens

Due to an issue with the OWLCS Core Platform CIE-based installer, the JAWS tool cannot correctly read the installation screens. To work around this issue, you must run the installer in silent mode. For information on Silent Mode installation, see Oracle WebLogic Communication Services Installation Guide.

16.2.8 Configure VoiceXML Driver Receive URLs Correctly

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).

16.3 Documentation Errata

This section details changes to the documentation since the last release. Topics include:

16.3.1 Create a Basic SIP Domain

Directions for creating a basic SIP Domain have changed slightly in this release. Please ensure that you follow these steps:

  1. Start the configuration wizard located at WLS_HOME/wlserver_10.3/common/bin/config.sh. This location has changed since the last release.

  2. Select Create a New WebLogic Domain, and click Next.

  3. Select Basic WebLogic SIP Server Domain, and click Next.

    The rest of the process remains the same as before when creating a WLS Domain.

16.3.2 Create a Custom AUID with OCP (Presence)

Follow these steps to create custom AUIDs:

  1. View the XML file for presence rules (presrules_au.xml). It is found in one of the following locations, depending on your installation:


    The file contains the following:

    • Name of the application (pres-rules)

    • Mime type

    • User Quota

    • List of schemas associated with the application's XML files

  2. Create a similar file for the new application usage

  3. For all the XSD files listed in the XML file above, create the XSD files and copy them to the XCAP config location mentioned in Step 1 above.

  4. cd $ORACLE_HOME/sdp/bin

  5. ./launch_sash.sh -a presenceapplication

  6. Provide admin credentials. At the sash prompt enter:

    xcap appusage create applicationUsage=<new application usage name>
    configurationFilename=<name of application usage XML file>

    For instance, this command was run to create the pres-rules application usage:

    xcap appusage create applicationUsage=pres-rules
  7. To provision users for the new application usage, at the sash prompt enter:

    xcap user add userName=<string> applicationUsage=<new application usage name>
    <string> is of the form username@example.com (replace example.com with domain
    for the deployment)

16.3.3 Cannot Create a SIP Server Domain Using Default WebLogic Platform Components

When running config.sh for SIP Server domain configuration, you can choose whether to use WebLogic Platform Components or a Custom Template. The default for Select Domain Source is to use WebLogic Platform Components. In previous releases, this selection worked, but does not in this release. You must select Custom Template in order to create a SIP Server domain.

16.3.4 Broken Documentation Links in Some (SIP Server) Translated Files

Some links to additional documentation were removed in the English language version, but broken links in translated (languages other than English) have been reported. These broken links are being addressed.

16.3.5 Missing (SIP Server) Online Help Regarding Security Providers

Online Help regarding Security Providers is not included. Oracle SIP Server, including information about security providers, is licensed and documented through OCCAS. Please consult your OCCAS documentation for more information.
