Last week, I wrote about the underlying changes made in the 7.2 release of the IBM i operating system for improved temporary storage tracking.
This week, I want to review the system status enhancements that allow you to better view and understand where the temporary storage is being used from a systemwide perspective.
Work with System Status (WRKSYSSTS)
Prior to the 7.2 release, WRKSYSSTS showed temporary storage as “Current unprotect used” and “Maximum unprotect” values. These have simply been reworded to be “Current temporary used” and “Peak temporary used,” as the following screen capture shows:
Using Navigator for i to view System Status, on the Disk Space tab, you will find the current and maximum temporary storage used values; these are not new and have been on the GUI System Status for some time.
What is new with the 7.2 release is the “Temporary Storage Details” button on this view, as you can see on the screen capture below.
When you click the “Temporary Storage Details” button, it will bring up a table of information regarding the temporary storage buckets that I wrote about last week. The example below shows the table of the temporary storage buckets that is displayed and the columns of information: the current bucket size, the bucket peak size, and the bucket limit size. (I’ll write about setting bucket limits in a future blog.) In addition, for any temporary storage bucket that is associated with a job, you will see information about that job, including the job name, user name, and job number along with the job status. As is the case with the Navigator GUI, all of these columns can be sorted, so it can be very easy to find the largest temporary storage bucket.
Navigator was enhanced at a later point in time to add a link to the Temporary Storage Details in the left navigation frame:
In addition to the capability to link the temporary storage buckets through the System Status interface, IBM i Services has a service for temporary storage – SYSTMPSTG. The temporary storage service provides a programmatic interface to access the temporary storage buckets and provides the same information as the GUI does. The SYSTMPSTG view contains one row for every temporary storage bucket that is tracking some amount of temporary storage across the system.
