derby.drda.traceDirectory property

The Network Server will attempt to create the trace directory (and any parent directories) if they do not exist. This will require that the Java security policy for derbynet.jar permits verification of the existence of the named trace directory and all necessary parent directories. For each directory created, the policy must allow

    permission java.io.FilePermission "<directory>", "read,write";
    

and for the trace directory itself, the policy must allow

    permission java.io.FilePermission "<tracedirectory>${/}-", "write";
