    Unhappy PL/SQL Developer hangs

    I am trying to create a view in PL/SQL Developer. I have two identical Oracle databases. The only difference in the databases is that one of them has 10 views created for it and the other doesn't. I want to create those 10 views in the lagging database. The syntax of the view is correct. The problem is that when I run the script in PL/SQL Developer the program hangs. Its says "executing..." and does nothing else. What could cause this hang?

    I see this with Forms Builder. If I am connected to a database doing some Forms work, and someone else is connected via SQL*Plus trying to compile something or run a script, the SQL*Plus session will hang (not all the time). I have to disconnect from the 9i database or use a separate one for Forms work.

    The issue of Form builder & SQL*Plus session getting hanged sounds intriguing. Does both sessions get hanged simultaneously? This form of locking is unheard of. What may be the probable cause?

    Forms session does not hang. Forms can be working on something entirely unrelated to the SQL*Plus session is trying to do.

    Did u detect any contention in V$LOCKED_OBJECT during this issue?

    locking

    It ended up being a locking issue. I shut the database down and brought it back up and all works well. Thanks for all of your replys;-)

    If we need to release the locks all we need is to kill the session that is causing the lock . If you are database is 24/7 OLTP . You can't do that for this simple reason.

    Try to find out the cause of such abnormal locking behaviour. Killing the session or shuting down DB will erase all evidence
