Defining Day and Night Operation

You can define separate operation modes for day and night operation. This means you can guarantee response times for important data entry transactions during the day, and use more work processes at night for job processing.

You are most likely to use the R/3 System for dialog processing between 6:00 and 20:00. Outside that time, system resources are normally required primarily for non-dialog processing (background jobs).

You can reconfigure your R/3 System dynamically at set times by switching operation modes and thus avoid the disadvantages of a system restart.

The diagram below illustrates the effect of an operation mode switch:

This graphic is explained in the accompanying text

Procedure

You can display the status of the operation modes and instances using the control panel. To do this, choose CCMS ® Control/Monitoring ® Control panel.


Assume that your R/3 System has a total of ten work processes available. Define an operation mode for night operation to allow more efficient data processing at night.

In the timetable for automatic operation mode switching, enter the times for the two operation modes:

  • 6 a.m. to 8 p.m. for day operation
  • 8 p.m. to 6 a.m. for night operation

Most R/3 resources will then be available for dialog processing during the day. At 8 p.m. the operation mode will be switched automatically, making more system resources available for background jobs and data transfer from other systems. At 6 a.m. the next day, the day operation mode will automatically be activated, making more system resources available for dialog processing.
