|Oracle® Fusion Middleware WebLogic Tuxedo Connector Administration Guide for Oracle WebLogic Server
11g Release 1 (10.3.5)
Part Number E13744-04
The following sections provide WebLogic Tuxedo Connector troubleshooting information.
The WebLogic Tuxedo Connector uses the WebLogic Server log file to record log information. To record log information you must:
TraceLevel is no longer supported, use system debugging. By default all the debug tracing is off. For information on how to set debug, see System Level Debug Settings.
For more information about setting WebLogic Server properties, see How to Set Oracle WebLogic Tuxedo Connector Properties.
Use the following procedure to specify that trace information is written to the log file:
Click the Server node in the left pane.
Select your server in the left pane.
Select the Logging tab.
In the General tab:
Check Debug to Stdout
Set Stdout severity threshold to Info.
To enable dumping of user data, add the following line to the
Enabling this causes user data to be dumped after the connection is connected. If no other debugging properties are enabled, then this will be the only WTC information dumped, except normal WTC error/informational messages. The dump is available in the WLS server log file.
The dump has the following format.
For outbound messages
Outbound UDATA: buffer type (<type>, <subtype>) +++++ User Data(size) +++++ ......
For inbound messages
Inbound UDATA: buffer type (<type>, <subtype>) +++++ User Data(size) +++++ ......
This section provides solutions to common user questions.
When I build the
simpserv example, I get the following error:
<date> <Error> <EJB> <EJB Deployment: Tolower has a class weblogic.wtc.jatmi.tpserviceHome which is in the classpath. This class should only be located in the ejb-jar file.>
This error message can be ignored for this release of the WebLogic Tuxedo Connector. The EJB wants all of the interfaces for an EJB call in the EJB jar file. However, some interfaces for the WebLogic Tuxedo Connector are implemented through the CLASSPATH, and the compiler throws an exception. When the EJB is deployed, the compiler complains that the EJB cannot be redeployed because some of its classes are found in the CLASSPATH.
Releases prior to WebLogic Server 7.0 used a WebLogic Server Startup class to start a WebLogic Tuxedo Connector session and a WebLogic Server Shutdown class to end a session. In WebLogic Server 8.1, WebLogic Tuxedo Connector sessions are managed using a WTC Service.
A WebLogic Tuxedo Connector session is started when a configured WTC Service is assigned to a selected server.
A WebLogic Tuxedo Connector session is ended by removing a WTC Service from the WebLogic server or when you shutdown the WebLogic server.
The Tuxedo Queuing Bridge is started if the Tuxedo Queuing Bridge and Redirections configurations exist in your WTC Service and the WTC Service is assigned to a selected server
The console displays an exception when I try to assign my WTC Service to a server. What should I do?
Make sure you have a valid WTC Service configured. Each WTC Service must have 1 or more Local Tuxedo Access Points configured before it can be assigned to a server. Your server log will display the following:
<Apr 22, 2002 4:21:35 PM EDT> <Error> <WTC> <180101> <At least one local domain has to be defined.>
I'm having trouble getting a connection established between Oracle WebLogic Tuxedo Connector and Tuxedo. What should I do?
Make sure you have started your Tuxedo server.
TraceLevel and enable Debug mode. Repeat the connectivity test and check the WebLogic Tuxedo Connector and Tuxedo log files for error messages.
Avoid using machine names or localhost. Always use an IP address when specifying a network location.
CredentialPolicy attributes. If your
LOCAL, you must register the remote domain
DOMAINID as a WebLogic Server user. For more information, see Section 3.5, "User Authentication".
If you are migrating from WebLogic Server 6.x and your applications use security, you need to set
PasswordKey as a WebLogic Server property. For more information, see Section 2.2.5, "How to Set Oracle WebLogic Tuxedo Connector Properties"
Check the WebLogic Tuxedo Connector configuration against the Tuxedo remote domain. The remote domain must match the name of a remote domain configured in Oracle WebLogic Tuxedo Connector.
For example: If the name
simpapp is configured in the Tuxedo DMCONFIG *DM_LOCAL_DOMAINS section, then this name must match the name in your Remote Tuxedo Access Point
Access Point Id attribute.
