Running a pack function

With the CRUISE pack function, you can pack the data structures to reduce DASD usage.

Before you begin

To run a CRUISE pack function, ensure that a parameter table with appropriate values is set up.

Procedure

  1. Enter the ZFCRU START command to verify and display the parameter table values.
    In the following example, parameter table values are verified and displayed for TABLE1.
    User:   WP/ZFCRU START-TABLE1

System: FCRU0149I 16.33.15 CPUB TABLE -TABLE1- ACTIVATED
        CSMP0097I 16.33.15 CPU-B SS-WP   SSU-WP1  IS-01
        FCRU0000I 16.33.15 PARAMETER TABLE DISPLAY FOR TABLE1
          FUNCTION                   PAC
          USABLE ECB START VALUE     40 PCT
          I-STREAM AFFINITY          BALANCE
          BUILD STATISTICS           YES
          NUMBER OF PRINT MESSAGES   ALL
          NUMBER OF LOG MESSAGES     ALL
          RESTORE OPTION             REBUILD/NORELEASE/NOFIXDIRECT
          SSU NAMES                  CURRENT
          INCLUDE SSU COMMON FILES   YES               
          MESSAGE AFTER EVERY ID     YES                
          AUTOMATIC PAUSE            YES
          REFERENCE ID               C090 - C099
        FCRU0000I 10.27.18 REPEAT ENTRY TO START CRUISE
    After the verification, the parameter table is in active state.
  2. If the parameter table values pass verification, enter the ZFCRU START command again to start the pack function.
    In the following example, the pack function is started for parameter table TABLE1.
    User:   ZFCRU START-TABLE1

System: FCRU0100I 10.27.19 CPUB TABLE -TABLE1-
                           FUNCTION-PAC STARTED

        FCRU0132I 10.27.28 CPUB TABLE -TABLE1-
                           FUNCTION-PAC COMPLETED
                           00000000 ERRORS DETECTED
    The parameter table is in running state during CRUISE pack function processing. When the CRUISE function is completed, the parameter table is in stopped state.
