Error description

  • New Function
    
    DEBCHK/K
    
    Note/s:
    
    The code added by this APAR also addresses an abend0c4 in
    IOSVCAPF which may occur under the following two conditions:
    
    1. 31-bit DASD UCBs have been implemented.
    2. The DD associated with the DCB parameter on the LOAD macro is
       incorrectly coded with SYSOUT=*, rather than DSN=dsname.
    
    This APAR adds code which verifies the DCB specified on the LOAD
    macro, and in this case will cause the LOAD to fail with an
    abend806, and message "CSV021I BLDL FAILED FOR MODULE modname,
    DCB INVALID"

Problem conclusion

Temporary fix

Comments

  • Options are being added to the existing DEBCHK macro which is
    documented in z/OS DFSMSdfp Advanced Services. With this PTF,
    supervisor state and/or system key (0 to 7) programs also can
    use DEBCHK to lock and unlock a DEB. Such a program might lock a
    DEB is to prevent that DEB from being freed while the DEB or any
    control block whose address is obtained directly or indirectly
    from the DEB is being used.
