JDBC Type 4 Driver 2.0 Programmer's Reference (SQL/MX 2.x)

If the data source named in serverDataSource is not available on the MXCS server, the
default server data source is used.
●
If the data source named in serverDataSource is not started on the MXCS server, an
SQLException is thrown.
●
Data type: String
Default: None (This value is treated as the default server data source.)
For example, the MXCS server default serverDataSource value is:
serverDataSource=MyDataSource
For more information about the default server data source, see the SQL/MX Connectivity Service Manual.
T4LogFile Property
The T4LogFile property sets the name of the logging file for the Type 4 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 file name is defined by the following pattern:
%h/t4sqlmx%u.log
where
/ represents the local pathname separator.
%h represents the value of the user.home system property.
%u represents a unique number to resolve conflicts.
Any valid file name for your system is allowed.
If you explicitly specify a log file, that file is overwritten each time a FileHandler is established
using that file name.
To retain previously created log files, use the standard java.util.logging file syntax to append a
unique number onto each log file. For example, you can have the following property in a data source:
T4LogFile = C:/temp/MyLogFile%u.log
That name causes the Type 4 driver to create a new log file using a unique name for each connection
made through that data source. For example:
C:/temp/MyLogFile43289.log
C:/temp/MyLogFile87634.log
C:/temp/MyLogFile27794.log
If you explicitly specify a log file that is not fully qualified, the Type 4 driver creates the file in the
