Execution Environment:     <SQL, SQL*Plus>Access Privileges:     SELECT on V_$LOCK, V_$SESSION, SYS.USER$, SYS.OBJ$ Usage:     sqlplus <user>/<pw> @[SCRIPTFILE]Instructions:PROOFREAD THIS SCRIPT BEFORE USING IT! Due to differences in the way text editors, e-mail packages, and operating systems handle text formatting (spaces, tabs, and carriage returns), this script may not be in an executable statewhen you first receive it. Check over the script to ensure that errors ofthis type are corrected.The script will produce an output file named [outputfile].This file can be viewed in a browser or uploaded for support analysis.

The following locking information script provides fully DECODED information regarding the locks currently held in the database. The report generated is fairly complex and difficult to read, but has considerable detail.
