    Hi All,

    Our application faced communication failures a few times in past week. The application logs shows following error:-

    "ERR 0 22 23:20:42-635 DbInterface OraDbInterface.C-3122 _checkerr: Error [3113] [Database Error: ORA-03113: end-of-file on communication channel] occured"

    1) I checked with the network team and they confirmed there was no network issues during this period. Our application runs on a separate server but is in same network as the Database servers (primary & Standby).

    2) There is no error in Alert logs(both primary & standby). The server process was absolutely fine when this error took place.

    3) There was no resource limit issue either.

    4) I also checked AWR report and there was not much load on the DB server during this time.

    I would be grateful if someone can let me know what else i can check and how i can better prepare myself in case i face this issue again.

    Thank you.

    Best Regards,
