Configuring dynamic response queue based on the input message parameter
Hi,
My application is uses JMS services to process inbout MQ message and send response. The source application structure will be changing to a clustered one and it will be having multiple response queue. My pega application needs to be configured to send the responses to these response queues based on the header property named ReplyToQ and ReplyToQMgr. I am using Connect-JMS to send the responses. Can soomeone assist me understanding how I will be able to achieve that? I am planning to create multiple JMS bindings eg "jms/Responses1", "jms/Responses2" in the server and refer them in the Connect-JMS rule dynamically based on the output of a decision table (the input to the decision table will be the properties from the input message header).
Can someone advise if this is a correct approach to set up dynamic response queue in Pega to deal with multiple response queues of the source system?

Your approach seems reasonable.
- Assuming you're using IBM WebsphereMQ, this reference is important to understand how headers are mapped:

Yes Manash, you approach is correct.
We also had the same requirement in our project and we also did something similar like below
1. Referred Data page on the Connect-JMS --> Response destination
like =D_ConnectionSettings.ResponseDestination.
2. When the request comes to PRPC, pass the header properties named ReplyToQ and ReplyToQMgr as parameters and initiate the data page.
- DataPage source Data Transform
- Call Decision Table from Data Transform by passing the above parameters and set the response queue name accordingly

Thanks for the confirmation on the approach. I have one more query on the mapping side.
The MQ message is somewhat like this (the source system hasnt completed their build)
message <MSG-TYPE : <8> <Datagram>
REPORT : <0>
REPLY TO QUEUE MANAGER : <XXXXXXX>
REPLY TO QUEUE : <XXXXXX>
BACKOUTCOUNT : <0>
MSG-ID : <5231303331343130303141434139443300000000>
CORR-ID : <000000000000000000000000>
MESSAGE :
I understand Pega captures the MQMD parameters ReplyToQ and ReplyToQMgr in one single standrd JMS property named JMSReplyTo (In the Srvice-JMS rule). Any idea how the output looks like when both ReplyToQ and ReplyToQMgr gets mapped to the same property. Is it a single string or some delimetred value?
