Hi Team,
Message flow contain MQ Input Node --> JCN --> MQ Output node.
"MQ Input" Node failure and catch terminals connected to MQ Output node.
This flow got a message and it contain list of batch identity details to be extracted from database. In Java compute node build multiplies messages per identity and send to target queue. Here We wanted to send all batch of messages to the target queue as single unit of work or no message if we have any exception in middle of building batch of messages. So we have set Transaction Mode as "YES" for MQ OutputNode, but we still facing issue like messages are not getting rollback to previous state and successfully build message went target queue if we got any exception in the middle of build other message. Can you please help me to resolve this issue.

IIB Version : 10.0.0.11
MQ Version : 8.0.0.5

What is the transactionality of the flow overall?

What method does the JCN use to connect to the database?

What is the correlation between input and output messages? Are you attempting:

1 input messages -> read database -> send 1-n messages or 0 messages?

or are you attempting:

batch of messages -> read database -> send 1-n messages or 0 messages?

Ans: using JCN provided getJDBCType4Connection() method got the DB connection.
