Hi,

Clarifying the problem statement again, Multiple requests are getting to our application server and using hibernate framework to persist the data into Postgres SQL DB but for one of the request, it is also similar request like other requests and there are no differences b/w these requests in terms of different OS, different network etc. but data is not persisting few times.

You have fallen into the trap of working the problem(repeating the 
problem definition) instead of working the solution, taking the steps to 
solve it. Start with acknowledging that this "...there are no 
differences b/w these requests ..." is not the case, otherwise we would 
not be having this discusion. This is going to involve working through 
the process from the front end to the database.

Start with:

How do you know which data is not persisting?

Did the INSERT entry you show below persist?

We have enabled below properties in postgresql.conf file and verified but didn't get any findings about the transaction and below log statements are writing in our data store logs.

log_statement = 'all'
logging_collector = on
log_min_messages = debug5
log_min_error_statement = debug5

Could you let us know any other way to trace out these kind of DB transactions?

Hi,

As l already mentioned, for this specific node also data is persisting but sometimes(randomly) data is not persisting.

How do you know which data is not persisting?

As you mentioned our application doesn't have any restrictions on OS level and on network etc.

different OS or OS version, different encoding, different location on the network, different data it is working, etc.

I don't understand what the above is saying. Do you mean there are differences in these attributes between the nodes or no differences?

Also please do not top post, use either bottom or inline posting per:
