LOGDSNALLOC

Indicates that you want z/OS® Debugger to create the log file data set specified by EQAOPTS LOGDSN command if it does not exist. You specify the EQAOPTS LOGDSNALLOC command with the corresponding allocation parameters for the data set, which z/OS Debugger uses when it creates the data set.

The following diagram describes the syntax of the LOGDSNALLOC command:

allocation_parms
Specifies the allocation parameters you want z/OS Debugger to use when it creates the data set. You can specify only the keys in the following list:
  • BLKSIZE
  • BLOCK
  • CYL
  • DATACLAS
  • DIR
  • DSNTYPE
  • DSORG
  • LRECL
  • MGMTCLAS
  • RECFM
  • SPACE
  • STORCLAS
  • TRACKS
  • UNIT
  • VOL
Separate the keys by one or more blanks. z/OS Debugger does not provide defaults for any of the keys.

For information on the format of the keys, see the chapter BPXWDYN: a text interface to dynamic allocation and dynamic output in the z/OS Using REXX and z/OS UNIX System Services manual. Specify that the data set be sequential. To learn about other formatting rules for the log file, see Data sets used by z/OS Debugger of the IBM® z/OS Debugger User's Guide.

LOUD
Specifies that z/OS Debugger display WTO messages, which helps you debug processing done by this command. z/OS Debugger normally does not display any messages when it creates this data set. If you are trying to determine why the log file was not created, specify LOUD to view any messages.
