Goal

The Data Monitor (DAMON) and System Monitor (SYMON) jobs are designed to run jobs at specific intervals and days.  These intervals can vary between product versions, it is best to reference the appropriate documentation for your specific version and database type (Microsoft SQL Server, Oracle).  The goal of this solution is to provide examples and instruction for updating (changing) the run times for these database background jobs.

Note:  In versions PRIOR to the 8.x versions, the data_monitor process ran every 5 minutes on a daily basis.  In the 8.x versions, it is only scheduled to run on a weekly basis.

More information regarding what these background jobs are can be found in the Administrator's Guide under the section Database Administration using one of the following locations:

If using P6 r8.x: If using P6 v7:
If using P6 v6.0, v6.1 or v6.2.1:
  • P6 v6.x physical media, see \Documentation\<language>\Construction and Engineering\adminguide.pdf
  • P6 v6.x physical media, see \Documentation\<language>\Public and A&D\adminguide.pdf
  • P6 v6.x physical media, see \Documentation\<language>\Power, Energy, and Process\adminguide.pdf
The components of interest which describe in detail what the background processes are within the Database Administration section are:
  • Background Processes and Clean Up in P6
  • Configuring the RDBMS Scheduler
  • Settings Table
  • Reading and Writing Setting Values
  • Tracking Background Job Execution
  • SYMON (System Monitor)
