#       Author :        
#
#       Description :   This script will map an OS process
#                       to a SQL sid and serial and turn on
#                       tracing using DBMS_MONITOR.SESSION_TRACE_ENABLE.
#                       Using the disable parameter the script will also
#                       disable a trace using
#                       DBMS_MONITOR.SESSION_TRACE_DISABLE.
#
#       Parameters :    $1 - UNIX process id. (Mandatory)
#                       $2 - disable or DISABLE (Optional)
#
#       Notes:          In order to use this script a file called locked
#                       needs to be set-up that contains the encrypted
#                       database SYSTEM password.
#                       To set-up the locked file follow these steps
#
#                       1. Create a temporary file called unlocked
#                          containing the SYSTEM password.
#                       2. Run the following command
#
#                          crypt key locked
#
#                          where key=encryption key.
#
#                       3. Delete the unlocked file.
#
#                       4. Set permissions on file locked to 400.
#
#                       5. Update line 96 of this script with the
#                          encryption key.
#
#                       The script works using a hardcoded SID.
#                       Update the SID on line 90.
#

#                       within this script meets their needs and is
#                       suitable for use.
