The Start Db2 Trace Request panel provides access to the following panels which you can use to perform the following tasks, overriding default settings such as:
Panel | Task |
|---|---|
Selection criteria | Select the threads to be traced. |
Exception filters | Reduce the amount of data saved. |
Detail trace options | Trace additional events. |
Trace log data set options | Specify additional data set allocation and processing options. |
Additional trace targets | Start the same trace for multiple targets. |
The following table describes the trace request keywords:
Keyword | Description |
|---|---|
id | To run multiple trace requests, specify an ID in the PARM field to make the trace unique. The identifier is used to specify which set of trace data to display with the application trace services. |
S | D | S (the default) requests a summary application trace of completed transactions. D requests a detail application trace that also collects major events in the life of the transaction. |
n | For full-screen trace displays, this value determines the size of the online trace display buffer to contain the trace entries per active trace. The size is specified in K format, where KB is the number of 1024 byte blocks. For example, 200KB is 200*1024=204800 bytes This value is primed from the default specified in DMRBEXxx. If you do not specify a value, the value from BBIISPxx is used. For a detail trace, this value must be at least four times TRSIZE value. Otherwise, it is adjusted up to the maximum of 16,383 KB. |
N | Y | This value specifies whether to write all trace records for this request to a unique trace log data set (TLDS) for this trace. If you specify Y with no additional summary or detail trace logging options, a single data set is allocated dynamically with the defaults specified in DMRBEXxx for this Db2 subsystem. |
c...c | This value defines a title for the trace (1 to 24 characters). If you are logging the trace, we recommend that you specify a more specific title to help identify the contents of this trace later. |
hh:mm:ss | This value requests trace start time. If the time specified is more than 10 minutes prior to the current time, 24 hours are added to the specified time and the request is started the next day. To start a request at midnight, specify 24:00:00. The default is the next full minute. |
nnn | hh:mm:ss | This value requests trace stop limit as a timestamp or number of minutes to process. The default is set from the TRTIME value in DMRBEXxx. Processing ends at the end of the last interval before the specified stop time. This time is displayed in the STOP field when the request is viewed with the R, P, M, and W line commands from the CT view. |
Y | N | The buffer is used in a wraparound method to store the entries. The wrap can be automatic, WRAP=Y (default), or user-controlled, (WRAP=N). |
HOT | PUR | QIS | This value defines the restart option to be used when a service is quiesced because of an inactive Db2 subsystem or BLK=RRR (restart all monitors) request, as follows:
