System Logger provides the ability to enable additional
diagnostics at the log stream level by specifying DIAG=YES on
the log stream definition.
The additional diagnostics that can be enabled at the log stream
level are listed here.
- When the appropriate specifications are set for the IXGCONN,
IXGDELET or IXGBRWSE service, the application can collect additional
diagnosis information. For more details, see the topic about "Dumping
on data loss (804-type) conditions" in z/OS MVS Programming: Assembler Services Guide.
