derby.drda.traceDirectory property

Indicates the location of tracing files.

Security Considerations

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";
    

See Customizing the Network Server's security policy for information about customizing the Network Server's security policy.

Syntax

derby.drda.traceDirectory=tracefiledirectory

Default

If the derby.system.home property has been set, it is the default. Otherwise, the default is the current directory.

Example

derby.drda.traceDirectory=c:/Derby/trace

Static or dynamic

Dynamic. System values can be changed by using commands or the servlet interface after the Network Server has been started.
