Issue/Introduction

Is there a task list to change the collection interval time?

 

Environment

Release: R20
Component: PDT

Resolution

The steps below can be used to change the interval time for non-cross system collections. In this example the Interval time is being changed from 4 hours to 1 hour:

1) If you start collections using MVS Modify commands, change the INT value in your collections from (0400) to INT(0100) 

2) If you start collections using the Online panels, change the "Interval Time ==>" value on the "DETECTOR Start Collection Display" to ==> 01 : 00 

Since the Maximum Number of Intervals value cannot be increased you may want to create a new Datastore. This is because you will now use 4 intervals to collect the same amount of data that you used to collect in 1 interval. Hence, 24 hours of data will now take 24 intervals instead of 6. Therefore, your current Maximum Number of Intervals value will need to be increased by 4 on the new Datastore. The easiest way to do this is: 

1) Create a new temporary Datastore on the Online panels (Option 7) 

2) Stop your current collection 

3) Use the PDTDSCPY job in your <High.Level>.CDBAJCL library to copy your current Datastore into a Temporary one 

4) Verify that you can see the data on your Temporary Datastore correctly. If so, delete your current Datastore using option 2 on the Detector Main menu 

5) Recreate your current Datastore with a "Maximum Number of Intervals" value 4 times greater than it currently is. (You can also use the PDTDSALC job in your <High.Level>.CDBAJCL library to recreate your Datastore. If you use this job, make sure that your MAXI parameter value is 4 times greater than it currently is)

6) Use the PDTDSCPY job to copy your Temporary Datastore into the Datastore that you created in Step 5 

7) Verify that you can see the data on your Step 5 Datastore correctly. If so, delete your Temporary Datastore 

8) Restart your collection 

 

 

Additional Information

Determine whether or not you are running cross system collections. If so, consider knowledgebase article : My SYSPLEX interval time for my collections is 1 hour. How can I change this?
