The create controlfile worked fine, but the system tablespace needed recovery and unfortunately the archives were corrupted too.   I just paid my price.   Gracias,   Ramon E.

Basically, you trim off everything above the 'STARTUP MOUNT' command, start svrmgrl, and execute the script.   Remember, you need to put in your own database name, path names, and file names.  If you don't know your database's file locations you'll have to go hunting.  This is for an 8.1.6 database - I forget what version you're using.  The only significant difference will be the 'ADD TEMPFILE' command at the end - that is for 8iR2 and higher.   I recommend that since you're unfamiliar with this technique, that you create a test database, delete the control files, and practice running this script there until you're confident that you can run it against production.   Good Luck!
