Example 1: Level 2 CHECK TABLESPACE of a segmented table space
This example illustrates a CHECK TABLESPACE job that performs level 2 (both intrapage and interpage) checking on all pages in the specified segmented table space. In addition, it performs column data verifications.
This CHECK TABLESPACE job reports two errors (see message BMC52288I). These errors are violations of column conditions that were specified with the VERIFY option of the RULES specification. Because of these errors, the utility completes with return code 4.
Messages BMC52471I list the columns specified in the failed condition along with corresponding column values.
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 1
Command options used in JCL | Description |
|---|---|
CHECKTSLEVEL 2 | Performs all CHECKTSLEVEL 1 checks on the specified table space plus additional interpage checks on such items as:
|
RULES FOR | Allows you to define RI and column condition rules for CHECK PLUS to verify for the specified table |
VERIFY | Allows you to specify the condition that must be true for a column value to be valid |
JCL for example
//CHECK01 EXEC PGM=ACKUMAIN,
// PARM=(DECA,ACKEX01,NEW,,'MSGLEVEL(1)')
//STEPLIB DD DISP=SHR,DSN=product.libraries
// DD DISP=SHR,DSN=DB2.DSNEXIT
// DD DISP=SHR,DSN=DB2.DSNLOAD
//SYSIN DD *
