![]() APAR status Closed as program error. Error description In a multi-node WebSphere environment, if a node specified in one of the JDBC Provider entries is down, users trying to administer datasources may experience erroneous error messages on the console, stack traces in the tracefile, and may not be able to create datasources using the datasource wizard in the admin console. There are also additional misbehaviors in the admin console in this situation.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application * * Server 4.0 * **************************************************************** * PROBLEM DESCRIPTION: In a multi-node environment, if user * * tried to administer a datasource with * * one or more nodes down, exceptions * * may be seen in the tracefile and parts * * of some admin console panels will be * * missing. * **************************************************************** * RECOMMENDATION: * **************************************************************** This problem only occurs in a multi-node (single repository) environment. Depending on how datasources were installed and which node initially created the repository, the symptoms of the problem may vary. Basically, the root problem is due to improper processing of the exception thrown when a remote node is down - the recovery attempt was somewhat less than elegant.Problem conclusion Modified code to check to see whether remote node is active before relying on it to provide information. Also modified some code paths so that, instead of just giving up (and, hence not giving info needed to create admin console panels), we recover and return to the correct code path.Temporary fix Test fix for PQ70860 placed on pq99999.raleigh.ibm.com approx. 1 1:45 AM (CST) on 17Mar03.
