2019 Mq Error Code
Contents |
a different DB2 stored procedure than the MQOPEN 2019 RC2019 MQRC_HOBJ_ERROR db2 stored procedure mqopen mqconn mqput mqget hconn connection handle hobj object Technote (troubleshooting) Problem(Abstract) You pass a mqrc hobj error Unit of Work (UOW) from DB2 through RRS under control of WLM to WebSphere mq reason code 2019 MQ. For the application, it is important to keep the WebSphere MQ Queue OPEN until all your messages have been mq error code 2539 passed to WebSphere MQ. You call a stored procedure which writes to WebSphere MQ. If the same procedure makes 2 successive PUTS (in the same invocation), it works. However, if you invoke the stored procedure mq error code 2033 again, the queue looks closed (RC2019). When this happens, you have to make a new connection for example, MQCONN, MQOPEN and MQPUT. Cause Each time a DB2 stored procedure is invoked in a WLM address space, it executes under a different DB2 private RRS context. The WebSphere MQ handles are associated with this RRS context, which is why the RC2019 occurs. Resolving the problem Do not carry MQOPEN variables
Mq Error Code 2018
across multiple calls to the same stored procedure. A new MQOPEN must be issued. Alternatively, the problem does not occur when you pass the UOW to WebSphere MQ thru RRS which is not WLM controlled. Also, when you send the same UOW directly from DB2SPAS to WebSphere MQ, the queue stays open until your explicit MQCLOSE command. Additional information Storing the hConn in a table is an acceptable way of avoiding multiple MQCONNs for the same TCB. Having said that, this is unnecessary as long as the stored procedure does not issue an MQDISC. The stored procedure can simply always issue an MQCONN. If the TCB has never been connected then the MQCONN completes with MQCC_OK and returns the hConn. If the TCB has already been connected, then the MQCONN will return with MQCC_WARNING, MQRC_ALREADY_CONNECTED, and the hConn will again be returned.

All the connections are established when the service is brought up in Websphere. My application is hosted on WebSphere 6.1.0.11. On every incoming message to a particular queue my program consumes it and onmessage() some other message will be send to a different queue. My program is able to mq error code consume the first message but fails to write into the other queue. I'm getting two errors, first MQ Exception 2009 and next MQ Exception 2019 I did some search on the below error which is an extract from my log created for the program. People are saying its related to some MQ problem or something external rather than my application. Its a known issue and they even have a fix in MQ for AIX but sadly couldn't find any for Windows. Anybody there who can help me by letting me know how to handle this programmatically. As far as connection objects are concerned it is not losing the object or getting null. Everything seems to ok. But rather I believe there is some problem on the physical connection between the MQ and WebSphere. I'm not sure too. But please provide me your valuable suggestions. I tried changing the WebSphere connection pool and session pool settings to Entirepool and all but no Luck!
