TRACE lists can be created for a more precise analysis of the execution of a UTM application. This list contains all UTM calls for the individual UTM processes in chronological order.
The TRACE list only ever contains the data for the first 6 processes. If data from more than 6 processes exists for the evaluation period, the TRACE2 table should be used for evaluation.
The list is sorted in chronological order.
The TIME STAMP column contains the time stamp of the corresponding call that was logged (to the nearest millisecond).
The TRACE list records the following events and data:
The transaction code called (TAC).
The transaction ID. In openUTM, a unique transaction ID is assigned to each transaction. This identifier is also transferred to the attached databases on the UTM-DB interface. In this way, it is possible to link database traces with these UTM traces and establish relationships between UTM and DB processes. The transaction ID is made up of four parts:
SC
Session counter: This numbers the application runs. The number is 1 after a regeneration, and is incremented by 1 each time the application starts.
VC
Service counter: This numbers the services within the application run and runs up to 16 777 216 (224).
TC
Transaction counter: This numbers the transactions within a service and runs up to 32 768 (215).
VN
Conversation number: This is the number of an internal UTM table for service administration.
These four parts are logged after the KDCS call INIT.
The VC and TC specifications are of interest to the user.All UTM calls with operation modifications. Internal UTM calls (WAIT, CONT, ...) are also listed. See the KCOP list.
The following are also logged:
KCMF for KCMF-relevant calls
KCRN for KCRN-relevant calls
KCLT for PADM/DADM calls
In the event of an abort with PEND ER/ FR as diagnostic information:
the TAC of the program unit that caused the abort
the return codes KCRCDC and KCRRCC
VC and TC for the assignment to the aborted service
With a PEND RS as diagnostic information:
the TAC of the current program unit
VC and TC for the assignment to the aborted service
As long as no process switch takes place, all calls for processing a dialog step are listed in succession in the same PID column. Following a PEND PA/PR/SP, a process switch can only occur with a change of TAC class. The interruption of a process by the operating system can be seen by the fact that the calls are continued in another process column midway through the processing of a dialog step.
