You can start the server in maintenance mode to avoid disruptions during maintenance and reconfiguration tasks.

About this task

Start the server in maintenance mode by running the DSMSERV utility with the MAINTENANCE parameter.

The following operations are disabled in maintenance mode:
  • Administrative command schedules
  • Client schedules
  • Reclamation of storage space on the server
