====== Oracle JDBC Thin Connection SQL*Net Trace ======


Trace über die Java Umgebung einschalten:

Anlegen einer Properity Datei für das Logging auf Console:

<code java>
.level=ALL
oracle.jdbc.level=ALL
oracle.jdbc.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=ALL
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
</code>


Anlegen einer Propertiy Datei für das Logging in eine Datei:

<code java>
.level=SEVERE
oracle.jdbc.level=INFO
oracle.jdbc.handlers=java.util.logging.FileHandler
java.util.logging.FileHandler.level=INFO
java.util.logging.FileHandler.pattern=jdbc.log
java.util.logging.FileHandler.count=1
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
</code>

Aufruf des Java Programms mit Trace Parameter:

<code bash>
java -Doracle.jdbc.Trace=true -Djava.util.logging.config.file=d:\jdbctrace.properties <class_name>
</code>

Im Klassenpfad müssen die _g jdbc Klassen wie ojdbc6_g.jar verwendet werden! 

Trace Level:
  * **OFF** Turns off logging.
  * **SEVERE** Logs SQLExceptions and internal errors.
  * **WARNING** Logs SQLWarnings and bad but not fatal internal conditions.
  * **INFO** Logs infrequent but significant events and errors. It produces a relatively low volume of log messages.
  * **CONFIG** Logs SQL strings that are executed.
  * **FINE** Logs the entry and exit to every public method providing a detailed trace of JDBC operations. It produces a fairly high volume of log messages.
  * **FINER** Logs calls to internal methods.
  * **FINEST** Logs calls to high volume internal methods.
  * **ALL** Logs all the details. This is the most detailed level of logging.

Einschränken auf einzelne Klassen kann über den Klassennamen in der Propertie Datei erfolgen:
  * oracle.jdbc.driver.level = WARNING
  * oracle.jdbc.connector.level = WARNING
  * oracle.jdbc.internal.level = WARNING
  * oracle.jdbc.datum.level =  WARNING
  * oracle.jdbc.adt.level = WARNING
  * oracle.jdbc.conversion.level = WARNING
  * oracle.jdbc.adt.level = WARNING
  * oracle.jdbc.thin.level = WARNING
  * oracle.jdbc.datum.level = WARNING
  * oracle.jdbc.kprb.level = WARNING
  * oracle.jdbc.pool.level = WARNING
  * oracle.jdbc.xa.level = WARNING
  * oracle.jdbc.sqlj.level = WARNING
  * oracle.jdbc.oci.level = FINEST
  * oracle.jdbc.jpub.level = WARNING
