the V$LOCK database shows deadlocks. Most oracle "hangs" are caused by another, usually interactive process, that has a previous lock on a row. Your code performs DDL which does implicit locking (update, insert, etc.), so it is susceptible. Have your DBA clobber the offending process.

Example: We had lots of users who left for lunch in the middle of an update/insert Oracle form. Since we could not rewrite hundreds of forms to be better about transactions and locking, the DBA intervened and killed off the offending user process when a batch job got hung.

Consider DBA help.

Also oracle code example of a deadlock workaround:

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
