Known Problems

The following section describes problems that were found in WebLogic Real Time, Core Edition 1.1. Entries include a description of the problem, and a workaround or solution where appropriate.

Tracking Number
Description and Workaround
CR286073
On Sun Solaris 9 or 10 on Sparc, when installing WebLogic Real Time, Core Edition as an add-on to an existing WebLogic Server 9.1 installation, you must update the LD_LIBRARY_PATH variable to point to the sparc64 directory under ${weblogic91_home}/server/native/solaris.
Workaround or Solution:
Update the LD_LIBRARY_PATH variable by replacing all occurrences of ${weblogic91_home}/server/native/solaris/sparc with ${weblogic91_home}/server/native/solaris/sparc64 in the ${weblogic91_home}/common/bin/commEnv.sh file.
CR294076, CR283776
If you are using JRockit 1.5.0_07 (or later) with version 9.1 or 9.2 of WebLogic Server, an exception similar to the following is thrown when you start the server:

weblogic.management.ManagementException: [Management:141266]Parsing Failure in config.xml: javax.xml.namespace.QName; local class incompatible: stream classdesc serialVersionUID = 4418622981026545151, local class serialVersionUID = -9120448754896609940

The problem is actually with the 1.5.0_07 version (and later) of the JDK, in which there is an incompatible change of the serialVersionUID of the javax.xml.namespace.QName class.
Workaround or Solution:
To work around this problem, you must set the old compatibility value. You can do this by simply setting the system property:
com.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0
Or you can add the following option to the java command in the script you use to start WebLogic Server:
- Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0
CR307782
When installing WebLogic Real Time, Core Edition 1.1 (MP01) into an existing BEA_HOME directory that also contains a WebLogic Server 8.1 installation, the Review Installation Details window of the installer contains formatting errors that makes it difficult to read the overview of the WebLogic Real Time installation.
This problem occurs with the following configurations:
  • Microsoft Windows Server 2003 with JRockit 1.4.2 R27.1 (WebLogic Server 8.1)
  • Linux 32-bit with JRockit 1.4.2 R27.1 (WebLogic Server 8.1)
There is no workaround or solution to this problem.
