In Control Center and Discovery Center, scheduled jobs can run consecutively or concurrently, depending on whether you run the jobs now or at later times.

How jobs run also depends on the maximumWeight parameter set in the server configuration (config.txt) file:

  • If maximumWeight is 1, scheduled jobs run consecutively in sequential order.
  • If maximumWeight is greater than 1, scheduled jobs run concurrently up to the set value. For example, if maximumWeight = 10, up to ten scheduled jobs can run at the same time.
Note: Out of the box, maximumWeight is set to 2.

If you are using Trillium Discovery for Big Data, the value of the maximumWeight parameter must be 2 or greater to support multiple jobs running simultaneously. Otherwise, when you profile HDFS data sources on the edge node, the process will fail.

To configure scheduled jobs to run concurrently

  1. On the Trillium server system, stop the TSS scheduler service.
  2. Open the config.txt file for editing. The file is located in the following locations:
    • On Windows: C:\Program Files\Trillium Software\MBSW\17.1\etc
    • On UNIX: …install path/metabase/etc
  3. Go to the key scheduler section.
  4. Modify the value of the maximumWeight parameter as needed. For example, 
    key scheduler { 
      value port [get {public ports scheduler}] 
      value timeout [expr {5*60*1000}] 
      value maximumWeight 10
      }
  5. Save and close the file.
  6. Start the Trillium scheduler service.
