InfoCenter Home > 6.6.14.11: Recovering from data source configuration problems using the XAResources fileWhen a WebSphere application server starts, the product stores information about any JTA-enabled data sources used by the server. This information is needed to recover from server failures. The information is kept in the file: product_installation_root/properties/application_server_nameXAResources Every time the server comes up, the server runtime examines this file and attempts any needed recovery on the resources described in this file. In the event that a JTA-enabled DataSource is configured incorrectly, you might see server startup failures or warning messages due to the incorrectly-configured resources. For example, you might see the warning message: WTRN0025W: Can not create XAResource object There is a work-around for this problem, if you are sure that you do not have other JTA-enabled data sources on this server for which recovery needs to be driven. You can simply remove the application_server_nameXAResources file from the properties directory, correct the configuration error, and attempt to start the server again. The XAResources file will be re-created when the server starts. |
