I have already tuned below parameters as

max_prepared_transactions = 500
max_connection = 2000

The error seems self-explanatory...

Without any context no one is going to be able to guess why you have an
application trying to rollback a non-existent two-phase
prepared transaction. But likely the problem is not something under
PostgreSQL control.

Dear Team,

DB log.

We are using postgresql version = 9.2

ERROR:  prepared transaction with identifier "131077_AAAAAAAAAAAAAP//

I dont have such an ancient version of Pg to test with but if indeed
your application is not using bogus or already committed prepared xact
IDs, then did perhaps someone/thing mangle files in pg_twophase?
