DBMS Tracing Using Java Logging Package
DBMS trace output can be configured to be logged using the Java Logging package (java.util.logging). The JDBC Driver uses the following Java logger objects to output DBMS trace messages:
ingres.jdbc.dbms.trace.log
Logger used to enable DBMS trace output through Java Logging and the logger used to output the DBMS traces. An explicit tracing level must be configured for this logger to enable trace output. Traces are written to this logger at the INFO level, so a logging level of INFO is sufficient to enable Java Logging output.
If the system property ingres.jdbc.dbms.trace.log is defined, then DBMS tracing is written to the indicated log file and Java Logging is not used for trace output. If the system property ingres.jdbc.dbms.trace.log is not defined, then the Java Logger ingres.jdbc.dbms.trace.log is used if it is explicitly configured with a logging level of at least INFO. Logging output is written to the ingres.jdbc.dbms.trace.log at the INFO level.
