Example 3: Level 2 CHECK INDEX of a partitioned table space
This example illustrates a CHECK INDEX job that checks for consistency between table space rows and index entries, and performs intrapage and interpage checking for all indexes that are defined on the partitions that are specified in the PART option. The job also performs intrapage checking for all table space pages in the specified partitions. The example allocates 12 SORTWK data sets allowing the sort process to multitask.
This CHECK INDEX job reports one page error (see message BMC52288I). Messages BMC52220I and BMC52402W explain the error. In addition, message BMC52500W reports two key mismatches. Because of the page error, the utility terminates with return code 4.
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 3
Command options used in JCL | Description |
|---|---|
NAME | Identifies the indexes to check. In this example, the NAME option specifies the partitioned index. |
PART | Specifies the partitions to check. |
CHECKIXLEVEL 2 | Performs all CHECKIXLEVEL 1 checks plus checks on the correct relationships between index keys and table rows. |
CHECKTSLEVEL 1 | Performs primarily intrapage checks on header pages, space map pages, and data pages in the specified table space. |
