IBM DB2 User Manual

traceLevel
Specifies what to trace.
You can specify one or more of the following traces with the traceLevel
parameter:
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_NONE (X’00’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_CONNECTION_CALLS (X’01’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_STATEMENT_CALLS (X’02’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_RESULT_SET_CALLS (X’04’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_DRIVER_CONFIGURATION
(X’10’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_CONNECTS (X’20’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_DRDA_FLOWS (X’40’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_RESULT_SET_META_DATA
(X’80’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_PARAMETER_META_DATA
(X’100’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_DIAGNOSTICS (X’200’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_SQLJ (X’400’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_META_CALLS (X’2000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_DATASOURCE_CALLS (X’4000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_LARGE_OBJECT_CALLS
(X’8000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_T2ZOS (X’10000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_SYSTEM_MONITOR (X’20000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_TRACEPOINTS () (X’40000’)
v com.ibm.db2.jcc.DB2BaseDataSource.TRACE_ALL (X’FFFFFFFF’)
To specify more than one trace, use one of these techniques:
v Use bitwise OR (|) operators with two or more trace values. For
example, to trace DRDA flows and connection calls, specify this value
for traceLevel:
TRACE_DRDA_FLOWS|TRACE_CONNECTION_CALLS
v Use a bitwise complement (tilde (~)) operator with a trace value to
specify all except a certain trace. For example, to trace everything except
DRDA flows, specify this value for traceLevel:
~TRACE_DRDA_FLOWS
getTraceFileAppend
Format:
public abstract boolean getTraceFileAppend()
throws java.sql.SQLException
Returns true if trace records that are generated by the trace controller are
appended to the trace file. Otherwise, getTraceFileAppend returns false.
getTraceDirectory
Format:
public void getTraceDirectory()
throws java.sql.SQLException
Returns the name of the destination directory for trace records that are
generated by the trace controller, if it is set. Otherwise, getTraceDirectory
returns null.
getTraceLevel
Format:
