If you need for debug purpose to trace SQL statements from the oracle SQL driver, you should follow the directives given by oracle.
Mainly, you should select a debug enabled (ie: xxxx{{_g}.jar}} JDBC driver you need and replace the one you're
using in the lib folder of nuxeo. You should also activate the trace by adding the following line in nuxeo.conf.
Note: on windows, you should edit instead the nuxeoctl.bat command file and append the oracle system properties to
JAVA_OPTS line.
Here is the content of the demo OracleLog.properties configuration file from oracle that should be placed in the nuxeo log directory.
