Allocate IOA Conditions File

The DACNDF DD statement references the IOA Conditions file. It may refer to either of the following files:

• the production IOA Conditions file
  If this file is used, it only needs allocation.
• a test file used to simulate jobs planned for a future working day
  If a test file is used, an initial job step must allocate and format the simulation Active Jobs file. A date record is then generated for the date of the simulation. A User Daily job step then loads the required job orders into the simulation Active Jobs file.

This preparatory step can be automatically generated through the M3 online utility.

All jobs in the Active Jobs file participate in the simulation. For jobs that are currently executing at the time the simulation is running, it is assumed that they have already executed half of their average elapsed time.
