Diagnostics

Use this page to change the trace attributes of a server.
CAUTION:
Changing the properties of a registered server might cause application connection errors and loss of data.

Diagnostic Options

Trace Table Size
Specifies the number of entries the trace buffer can hold before it wraps to the start. 2 specifies there is space for one entry. If Auxiliary Trace Active is checked then each entry is written to disk, and the trace buffer is written to disk when it wraps.
Local Trace Size
Specifies the number of entries the local trace table can hold before it wraps back to the start. A value of 0 (zero) means that no local trace table is allocated. Each service execution process has its own local trace table. Each entry is 24 bytes long.
Maximum Diagnostics File Size
Specifies the maximum size of the auxiliary trace and dump file in kilobytes. A value of 0 (zero) means that the file can grow to the maximum file size supported; 4GB.
Cold Start Diagnostics File
Check this to specify that the auxiliary trace and dump files are to be deleted when the server starts.
Dump on System Abend
Check this to specify that the server should produce a dump if one of its own processes, such as a service execution process, terminates abnormally. The dump information can help you to determine the cause of the abnormal termination.
Auxiliary Trace Active
Check this to specify that trace records are to be flushed to disk before the trace table is overwritten. You should do this only if you have adequate disk space available, since the file can become very big very quickly. If you have a high-activity system use this field in conjunction with Maximum Diagnostics File Size to limit the disk usage. Writing out to a file also degrades performance.

Trace Flags

Use these flags to control what information is written to the trace file for this server. Any changes you make to these fields while a server is running take effect immediately.

Task Control
Check this to specify that the server is to trace its task control component.
Storage Control
Check this to specify that the server is to trace its storage control component.
Table Management
Check this to specify that the server is to trace its table management component.
Application Container
Check this to specify that the server is to trace its application container component.
Request Handler
Check this to specify that the server is to trace its request handler component.
RM Interface
Check this to specify that the server is to trace its resource manager interface component.
Communications
Check this to specify that the server is to trace its communications component.
Application
Check this to specify that the server is to trace the CICS API calls made by a CICS application.
Exit
Check this to specify that the server is to trace user and system exits.
