current working directory, for example, in the directory from which the JVM was invoked.
For detailed information about java.util.logging, see the logging summary at

T4LogLevel Property
The T4LogLevel property sets the logging levels that control logging output for the Type 4 driver. The
Java package java.util.logging logs error messages and traces messages in the driver.
Set this property on a DataSource object, ConnectionPoolDataSource object, or
DriverManager object. For information about how to set properties, see How to Specify JDBC Type
4 Properties.
Data type: String
Default: OFF
Logging Levels
OFF
is a special level that turns off logging; the default setting.
SEVERE
indicates a serious failure; usually applies to SQL exceptions generated by the Type 4 driver.
WARNING
indicates a potential problem, which usually applies to SQL warnings generated by the Type 4
driver.
INFO
provides informational messages, typically about connection pooling, statement pooling, and
resource usage. This information can help in tuning application performance.
CONFIG
provides static configuration messages that can include property values and other Type 4 driver
configuration information.
FINE
provides tracing information from the Type 4 driver methods described in the Type 4 driver API.
The level of tracing is equivalent to the level of tracing provided when calling the
setLogWriter() method of the DriverManager class or the DataSource class.
FINER
indicates a detailed tracing message for which internal Type 4 driver methods provide messages.
These messages can be useful in debugging the Type 4 driver.
