MustGather: Temporary Storage growth in *PROCESS bucket 2

Troubleshooting


Problem

Temporary storage analysis tools SYSTMPSTG or RMTSTG show large amounts of temporary storage consumed in *PROCESS bucket 2. This document describes what data to collect.

Diagnosing The Problem

Normally, the SYSTMPSTG view and output from the RMTSTG Advanced Analysis command show *PROCESS (bucket 2) with a size of zero. If bucket 2 is found to have a non-zero value, this usually indicates a temporary storage leak by one or more jobs that ended without freeing all of the temporary storage.

Step 1: Collect RMTSTG leak data

  • Run IBM i command STRSST and sign into System Service Tools
    Select Option 1 - Start a service tool, and press the Enter key
    Select Option 4 - Display/Alter/Dump, and press the Enter key
    Option 2 - Dump to printer, and press the Enter key
    Select Option 2 - Licensed Internal Code (LIC) data, and press the Enter key
    Select Option 14 - Advanced analysis, and press the Enter key
    Under Option, type 1, and type RMTSTG on the blank Command line and press the Enter key
    On the Options screen, type -L and press the Enter key
    On the Dump Title screen, change Through page to 99999999 and press the Enter key


Step 2: Collect the associated Licensed Internal Code log entries

  • Run IBM i command STRSST and sign into System Service Tools
    Select Option 1 - Start a service tool, and press the Enter key
    Select Option 5 - Licensed Internal Code log and press the Enter key
    Select Option 2 - Dump entries to printer and press the Enter key

    Press F3 to return to the Licensed Internal Code Log menu
    Select option 7 to Display the status of the Licensed Internal Code log and press the Enter key
