If you want to use the LOGR subsystem to read log stream data in
data set format, make sure of the following:
- The LOGR subsystem must be activated on each system where you
expect to use it.
Note that you cannot use either the SETSSI ACTIVATE
or SETSSI DEACTIVATE command to activate or deactivate the LOGR subsystem.
See the chapter on system logger functions in z/OS MVS Setting Up a Sysplex.
Each
system must have LOGR defined as a subsystem on the SUBSYS statement
in the job that runs the subsystem.
- The log stream owner must supply an exit that generates a view
of its log data. You can use this to ensure that the new application
program is written with the correct data format in mind. See z/OS MVS Programming: Assembler Services Guide.
- The system where the new log data reading application runs on
must be in the same sysplex as the log stream.
- The application must have the appropriate SAF authority (READ/WRITE)
to the log stream, SAF CLASS(LOGSTRM) RESOURCE(log_stream_name).
If
there is no log stream class defined to a security product such as RACF®,
no access checking is performed.
- Make sure the LOGR subsystem is activated.
