Hi MQ Gurus,
Can I use a client channel definition table for MQSeries Java Client API. My requirement is, I have two MQ Servers with same QMgr & Queue definitions. My application should connect to Server2 if server1 is not available. I heard, for C++ API, you can create a Channel definition table and set that in MQ Environment variables (MQCHLLIB, MQCHLTAB). Will this approach work for Java ? If not, can you please suggest the best way to do this ? Don't tell me I have to handle it myself in my application 
Thanks,
Vasu.

You have to handle it in your application
But seriously, in Java, this is a trivial task. Create a proerties file and write a trivial Java class that contains a HashTable, reads the properties file and then SuperClass MQQueueManager to map the queue manager name supplied to the MQEnvironment settings found in the HashTable. |

Hi Kolban,
Thanks for your reply & suggestion. Hey, I have one more question. In my Java application, is it a good idea to cache MQ Connections and reuse them, or is it a best practice to establish connection every time I need to send a message ? We are using MQ JMS API.
Thanks,
Vasu. |
