Tracing Application Engines

Tracing particular Process Definitions
This SQL script can make things a little clearer.

select '-TRACE ' || (
1    + -- Initiate the Application Engine Step trace
2    + -- Initiate the Application Engine SQL trace
4    + -- Trace dedicated Temp Table Allocation to AET file
128  + -- Initiate the Statement Timings trace to file, which is similar to the COBOL timings trace to file
256  + -- Initiate the PeopleCode Detail to the file for the Timings trace
1024 + -- Initiate the Statement Timings trace, but, instead of writing to the trace file, this trace stores the results in the following tables: PS_BAT_TIMINGS_LOG and PS_BAT_TIMINGS_DTL
2048 + -- Adding this value requests a database optimizer trace file
4096 + -- Request a database optimizer to be inserted in the Explain Plan Table of the current database
8192   -- This value sets a trace for Integration Broker transform programs
) as TRACE from dual;

select '-TOOLSTRACESQL ' || (
1    + -- Trace SQL statements
2    + -- Trace SQL statement variables
4    + -- Trace SQL connect, disconnect, commit and rollback
8    + -- Show fetched rows (indicates that it occurred, not data)
16   + -- Show all other API calls except ssb
32   + -- Set Select Buffers (identifies the attributes of columns to be selected).
64   + -- Show database API specific calls
128  + -- Show COBOL statement timings
256  + -- Show Sybase bind information
512  + -- Show Sybase fetch information
4096 + -- Show manager information
8192   -- Show Mapcore information
) as TOOLSTRACESQL from dual;

select '-TOOLSTRACEPC ' || (
1    + -- Trace instructions
2    + -- List the program
4    + -- Show assignments to variables
8    + -- Show fetched values
16   + -- Show stack
64   + -- Trace start of programs
128  + -- Trace external function calls
256  + -- Trace internal function calls
512  + -- Show parameter values
1024 + -- Show function return values
2048   -- Trace each statement in program
) as TOOLSTRACEPC from dual;

Tracing on the Server:
./psft/pt/8.52/appserv/*/psappsrv.cfg is where you can set tracing for Batch server instances.
