Element command overview

Each element on the Element Selection panel corresponds to one or more changeable items in a Db2 subsystem. With OPERTUNE, you can make immediate modifications to a ZPARM value without cycling the subsystem.

Before you begin

Before using any of the OPERTUNE elements, you must perform the following steps:

• Specify a valid target OPERTUNE and a valid Db2 subsystem or data sharing group (see  Selecting-a-target-OPERTUNE-and-subsystem ).
• Ensure that you have the proper authority to execute the command (see  Security ).

To access the element commands

1. Select the Subsystem parameters (ZPARMS) option from the Main Selection Menu to display the Element Selection panel.

2. Select one or more elements by typing any of the following line commands next to the elements and pressing Enter:

• 
  
  • Q to build a QUERY command
  • R to build a RESET command
  • S to build a SET command

  • SN to build a SET command with the NORESET option

    Note

    If you request a RESET for an element that cannot be reset (for example, EDMPOOL), OPERTUNE redisplays the selection list with that element at the top of the panel and places an asterisk (*) in the select field. You must make a new selection or replace the asterisk with a blank.
