ctquiet - Unix option to avoid disconnect

The potential for unintended user interference was greatly reduced in V10 by use of the USERPRF_ADMSPCL bit. This modification makes further improvements by providing an alternative approach to avoid disconnecting the ctquiet on Unix systems. When the optional -w COMMAND switch is used, the behavior of ctquiet is modified to perform as follows:

1. After successfully quieting the server, it makes a system call to execute COMMAND.
2. It remains connected and waits for SIGINT to unquiet the server. If ctquiet is killed before receiving SIGINT, the server will remain in a quiet state until a new connection unquiets the server.

When connecting to a quieted server with the intent to remove the quiet state when the original caller of ctquiet has disconnected you must now set the USERPRF_ADMSPCL bit.

Syntax:

ctquiet [-s server][-f][-u][-w command] {-p password|-a authfile}

• -s - Server (default: FAIRCOMS@localhost)
• -f - Full consistency (default: crash consistency)
• -u - Unquiet server
• -w - Execute command on successful quiet. Waits for SIGINT to unquiet server
• -a - Authentication file name
• -p - Admin Password
