Example 4: Level 1 CHECK INDEX of a specified index

This example shows a CHECK INDEX job that performs only level 1 checks on the pages in a specified index. No checks are performed on the consistency between index entries and data rows, and no checks are performed on the table space pages in the table space for which this index is defined.

This CHECK INDEX job reports one page error (see message BMC52288I). Messages BMC52221I and BMC52410I explain the error.

Message 50041I indicates the status of zIIP processing. For this example, the ZIIP installation option is ENABLED, but an XBM subsystem was not specified. CHECK PLUS automatically located an available XBM subsystem to provide zIIP processing.

Command options for example 4

Command options used in JCL	Description
NAME	Allows you to specify one or more indexes that you want to check
CHECKIXLEVEL 1	Performs checks on index header pages, space map pages, and root and leaf pages in the index
CHECKTSLEVEL 0	Performs no checks on table space pages other than those performed normally when reading rows from the specified table space
