Clarify difference between 'Move to available' and 'Resend message'

[Laurens-makel]

When you use a JdbcTableListener, you have two options available to deal with messages with an error status. You could select the message and press the resend selected button or you could press the move to available button.

To our understanding, the difference between those two is that move to available modifies the status column of the message and resets the value to statusValueAvailable, which causes the listener to process the message as if it was a completely new message, whilst resend just re-submits the message and sets the isRetry flag in the session.

Basically, move to available means 'pretend this message is completely new' and resend message means 'retry this message'.

Could you clarify what the exact differences are? How does this relate to the maxRetries attribute?

Hi,

That's pretty much it! Depending on your Listener configuration it will process it as a new message, but might use the same MessageId or CorrelationId. This can be particularly useful if you want to re-process large datasets, 'the normal way'.

It is also possible in certain cases to place message in a 'HOLD' state. Which can then be made available at a later time.

A manual retry will do a duplicate check (with messagelog) but will skip the ProblematicHistoryCheck (otherwise always enabled).
