  • General discussion


  • Since July 2018 our application developed in vb6 with ADO getting frequent run time errors in windows 7 32 bit OS.

    For instance "Operation not allowed when object is closed" errors. If user tries 3 or four times or next try it will be automatically resolved.

    We are creating connection thru dlls.

    For instance, there is "select abcd from ABC". sometime it throws run time errors next time it worked fine.

    All users are facing same issue randomly.[different places]

    Sometimes getting TNS timed out however next tries goes thru.

    We suspected that any issue in network fluctuation [network team says no issues]

    Suspecting any issue in DB [DB team says no issues]

    We observed, tnsping from client to server [checking in client pc]  tnsping goes 3030ms / 9310ms again back to 20ms.

    We suspect that any issue between network & DB due to which connection failure however unable to isolate the issue?

    All these issues started since end of July 2018. Our last application patch was applied in Mar 2018.

    Besides, our other application which is in power builder works fine however bit slowness for few days.

    Can anyone help us to isolate the issue.
