Function
Specifies a directory to which the
Derby Network Client will
send JDBC trace information. If the program or session has multiple connections,
the Network Client creates a separate file for each connection. By default, the
files are named _driver_0, _driver_1, and so
on. Use the
traceFile=path
attribute to specify a file name for the trace file.
If the directory does not exist,
Derby issues an error
message. If you do not specify an absolute path name, the directory is assumed
to be relative to the current directory.
For more information about tracing, see "Network client tracing" in the
Derby Server and Administration Guide. See
traceFile=path,
traceFileAppend=true,
and
traceLevel=value
for other attributes related to tracing.
Examples
-- enable tracing on an existing database that will have multiple connections
jdbc:derby://localhost:1527/mydb;traceDirectory=/home/mydir/mydbtracedir
-- specify a trace file name within the directory
jdbc:derby://localhost:1527/mydb;traceDirectory=/home/mydir/mydbtracedir;traceFile=trace.out
-- append to the default trace file
jdbc:derby://localhost:1527/mydb;traceDirectory=/home/mydir/mydbtracedir;traceFileAppend=true
