I have a requirement to know the statistics of message in a queue. The queue has 9 Million messages(accumulated over a week) which are sit in the queue for a dry-run testing. Application team needs to know some specific details from the statistics. I realize that MQ is not a DB to query in such a way. However I am curious to know if any tool / support pac serve this requirement.
1. Count of messages which are published on a particular day
2. Count of messages and on and after any date |

That is a huge number and any tool is going to run slowly.
You could use the QLOAD tool to unload the queue to a file using date range criteria and see how many messages get unloaded (you can delete the file or use /dev/null).
Make sure to run qload locally on the same host as the QM for this purpose.
Qload is support pac MO03 or the replacement in MQ v8 of dmpmqmsg

Also you could modify amqsbcg to only print out the relevant parts of the mqmd (putdate/puttime)... and modify it to use a 1 byte long buffer.
Or pipe the output to something that would filter and only show/count the data you wanted.
Either choice is going to get slower the further down the queue you get. The first choice won't be as slow (maybe), and won't take nearly as much memory.
I think in order to really do what you wanted, you would have needed to capture the statistics as the messages were being put.

This is correct, but I think the OP is trying to gather this information for a large depth of messages that were put with this switched off. Hopefully the OP will take the advice to switch it on in future.
