The following is copied from Eclipse' documentation and provided here for reference:


When you need to perform critical system maintenance, nobody at the site can be logged on to the system. The person doing the maintenance needs to verify that nobody is logged on and then use the System Lockout Control program to restrict system access until the maintenance is finished. If you try to access the system during a lockout, the following message displays: System shut down for maintenance.


Only the system administrator or Eclipse Support personnel should use this program.


To initiate a system lockout

  1. From the System (F2) > System Programming (S) > System Maintenance (M menu, select System Lock Out Control (L) to display the System Lock Out Control screen.

Note: If prompted, log on to the character-based system.

  1. In the Lock Out System Access Until field, enter the date and time to free the system for access.
  1. In the Lockout Bypass Password field, enter a password authorized personnel can use during a lockout to bypass the System Lockout screen and access the system to verify, for example, that file resizing has finished.

Note: Although this field is optional, we suggest that you enter a bypass password.

  1. In the Disable System Admin Phantom? (Y/N) field, enter Y to disable the normal phantom scheduling so that no jobs start from the Phantom Scheduler queue while the system lockout is in effect.

When the lockout terminates, the Phantom Scheduler starts all jobs that were scheduled to run during the lockout time.

  1. Press Esc to exit the screen and begin the lockout.

To cancel a system lockout

  1. From the System > System Programming > System Maintenance menu, select System Lock Out Control to display the System Lock Out Control screen.

Note: If prompted, log on to the character-based system.

You need a password to access the system during a lockout.

  1. Do not complete the fields or change the default values on the screen.
  2. Press Esc to exit the screen and clear the lockout.


Note: there is no way for Solar users to enter a lockout password, so if you want to selectively allow users to access Solar while the lockout is in place, you'll need to manually edit the SYSTEM.LOCKOUT.EXCEPTIONS control file and add the Eclipse users that should be granted Solar access:
