Chapter 16. Tracing IBM Data Server Driver for JDBC and
SQLJ C/C++ native driver code
To debug applications that use IBM Data Server Driver for JDBC and SQLJ type 2
connectivity on DB2 for z/OS, you might need to trace the C/C++ native driver
code.
To collect, format, and print the trace data for the C/C++ native driver code,
follow these steps:
1. Enable tracing of C/C++ native driver code by setting a value for the
2. Run the db2jcctrace command from the z/OS UNIX System Services command
Suppose that db2.jcc.t2zosTraceFile has this setting:
db2.jcc.t2zosTraceFile=/SYSTEM/tmp/jdbctraceNative
Execute this command to format all available trace data for the C/C++ native
driver code, and send the output to stdout:
db2jcctrace format flow /SYSTEM/tmp/jdbctraceNative
db2jcctrace - Format IBM Data Server Driver for JDBC and SQLJ trace
data for C/C++ native driver code
db2jcctrace writes formatted trace data for traces of C/C++ native driver code
under IBM Data Server Driver for JDBC and SQLJ type 2 connectivity.
By default, the trace data is written to stdout. You can pipe the output to any file.
