Logging to a Print Device

Under z/OS

Specify a SYSOUT class for printed output (for example, SYSOUT=A) in the log-file DD statement of the DC/UCF startup JCL.

A log directed to a print device is not printed until the system is shut down. An alternate log file assignment is usually not necessary when logging to a print device under z/OS.

Note: This release of CA IDMS supports z/OS V2R10 as well as z/OS 1.1 and higher. However, we will always refer to z/OS in this document.

Under z/VSE

Specify either SYSLST or a specific print device in the LOG parameter of the SYSTEM statement. The following considerations apply:

• SYSLST—A log directed to SYSLST normally is not printed until the system is shut down. An alternate log file assignment is not necessary when logging to SYSLST.

  Note: Because SYSLST can be assigned to output media other than a print device, the DC/UCF startup JCL must specify the output medium required. Typically, SYSLST is assigned to a print device for DC/UCF logging. However, you can use SYSLST to direct the log to a tape device.

• Specific print device—The log can be directed to a specific print device under either of the following circumstances:
  • The system has available one or more printers other than the printer to which SYSLST is routed.
  • The system is running in a partition controlled by a spooler such as POWER/VS, where multiple dummy printers can be assigned within the partition.

A log directed to a specific print device can be printed while the system is active. If you assign an alternate log file, the system begins logging to the alternate file when the record count for the active file is exceeded. If you do not assign an alternate log file, the system closes and then immediately reopens the log file when the record count for the file is exceeded.

Under z/VM

Specify either PRINTER or the virtual address of a print device in the log-file FILEDEF command. A log directed to a print device can be printed while the system is active by closing and reopening the file.
