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 there is no maximum
size.
- 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.
