The ccmdb protect command prevents users from starting new sessions on the protected database.
You want to prevent users from starting new sessions if a database is corrupted or if you are installing a model into a database.
The user for this command is the Rational® Synergy administrator.
This command prevents new sessions from being started on the specified database. However, it does not protect the database from sessions already running. Stop current sessions by running the ccmdb shutdown command.
