OMB script to remove DBLink and Schema configuration from mapping

Question

In OWB903 we have used prefixes for most of our tables used in mappings. (By right clicking on the mapping, choosing configure and then setting the Schema/DB Link for each table under "Sources and Targets")
We are now in the process of upgrading to OWB 904, and because of the way OWB 904 handles locations we would like to remove the prefixes from the mapping configurations. Our project consists of 100+ mappings, so it would be nice if it was possible to do this by runing a OMB script.
I would appreciate it very much if anybody can come up with an example of how to do this.

Roald,
Here is an example of a OMB script that renames all the tables in a project (to run a script, you have to open the OMBPlus application and enter 'source <filename>' on the prompt, where filename is the name of the file containing the script):
# rename.tcl
# Renames the names of tables, mappings, cubes and dimension for a project.
# Prefixes the names with 'WH_'
# Please update the connection information here.
# The connect string format is repository_user/repository_pwd@hostname:port:service_name
# Connecting to the repository:
OMBCONNECT owb904/owb904@localhost:1521:ora9201
puts "Connected to repository."
# Setting the project and prefix variables (set project name here):
set MProject MY_PROJECT
set wh WH_
#Open the project
# Entering into the Project (CC = Changing Context):
OMBCC '$MProject'
set module_list [OMBLIST ORACLE_MODULES]
# Loop to enter into each project module:
     foreach i in {$module_list}{
          puts "Working on module: $module_list ."
          OMBCC '$module_list'
          set table_list [OMBLIST TABLES]
# Loop to prefix the name of each table in the current module:
               foreach j in {$table_list}{
                    puts "     Working on table: $table_list ."
                    OMBALTER TABLE '$j'
                         RENAME TO '$wh$j'
puts "Done."
# Saving the changes:
OMBCOMMIT
# Disconnecting from the repository:
OMBDISCONNECT
As you know, OMBPlus is based on the TCL scripting language. For more info on TCL, take a look at:

Also, for more info on the OWB specific commands, take a look at the Users guide.
