Logging

The SDSF server logs all statements processed, and any associated error messages, to a log file. With the server START command, you can control the destination of the log file (SYSOUT or the hardcopy log). When the destination is SYSOUT, SDSF uses the class specified in the server JCL if one is specified there, or the class specified in the LOGCLASS option on the START command. If no SYSOUT class is specified, SDSF uses class A. When SDSF dynamically allocates the log, it is freed when it is closed. In the event of an error allocating the log, SDSF redirects any log messages to the hardcopy log. Messages issued by the server are documented in SDSF messages and codes.

The SDSFAUX log is written to the HSFLOG data set allocated by the SDSF server address space. It contains messages related to processing for use by IBM service personnel.
