http://issues.apache.org/bugzilla/show_bug.cgi?id=30391 dbcp connection object hangs Summary: dbcp connection object hangs Product: Commons Version: 1.1 Final Platform: Other OS/Version: Linux Status: NEW Severity: Critical Priority: Other Component: Dbcp AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When the network connection between tomcat 4.1.29 and database (experienced with sybase ASE 12.5) is lost, the 'Connection' hangs indefinitely. It hangs in the line of code "con = DatasourceObject.getConnection();" None of the other options in the connection pooling stuff - add info: used SharedPoolDatasourceFactory in dbcp - like maxWait / validationQuery /removeAbandoned/ removeAbandonedTimeout etc doesnt timeout the connection. Analysis: When the network connection to the database is fine (normal scenario)- the dbcp gets a connection from the datasource (connection pool)- sets three params - autocommit, readonly and isolation level for the connection object and returns this improved connection object to the calling class. Now say the network connection is lost, and the unaware application requests for a connection from the pool, gets the connection object and then tries to set the first of three params (autocommit- mentioned above) where it hangs. None of the timeout params work in this scenario. Setting a validationQuery tries its validation only after getting the connection object which never happens. Soln(possibility): after getting the raw connection object - run a validation query (or any call to database)with a stmt.setQueryTimeout() set to say 3-5 secs - or say configurable by user - and then catch the exception (noroutetohost exception) to throw it back. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
