Class OracleLog

  oracle.jdbc.driver.OracleLog

public class OracleLog
extends java.lang.Object

TRACE is a static variable that enables/ disables the invocation of the print calls during run-time. This static variable can be changed to 'static final' to allow the print calls to be compiled out completely.

Logging can also be controlled/filtered by using Java system properties. Note that system properties only work in Java applications but not in Applets. Note that the system propeties are examined once when the OracleLog class is loaded. These properties are listed in the following:

• oracle.jdbc.Trace Set this property to "true" to enable logging with default settings. Setting any other property automatically turns this on on.

Since:

8.1.6

Method Detail

isDebugZip

public static boolean isDebugZip()

Check if the Oracle Jdbc zip/jar file being used has the logging facility avaliable. Note that the logging facility is only available in the debug zip/jar files.

Returns:

true if a debug zip/jar file is being used, or false if not.

isEnabled

public static boolean isEnabled()

Check if logging is enabled.

Returns:

true if logging is enabled, or false if not.

registerClassNameAndGetCurrentTraceSetting

public static boolean registerClassNameAndGetCurrentTraceSetting(java.lang.Class classObj)

setTrace

public static void setTrace(boolean enable)

Set the tracing enable variable.

setupFromSystemProperties

public static void setupFromSystemProperties()

This method uses System.getProperty() to read properties to control logging. Properties are not available in an applet environment or whenver security setting prevent it.
