OCITransCommit can't return in high availability test


    I found a problem maybe a bug about the OCITransCommit when I was testing the high availability of my application on Linux.

    First I started my application, it would do some database manipulation. Then I shuted down the oracle server. Then there was a chance the application would hang.

    The function stack showed the application was running the OCITransCommit function, and OCITransCommit could never return in couple of hours.

    Can any guys tell me what OCITransCommit function is doing and why it could not return. Need your help.
