How to Use the Distributed Tuning Interface

Header Files

The header files that you need to include for DTI are:

#include <btitypes.h> 
#include <dticonst.h> 
#include <catalog.h> 
#include <ddf.h> 
#include <connect.h> 
#include <config.h> 
#include <monitor.h> 
#include <dtilicense.h> 

You also need to link to the import library (current version is W3DBAV90.LIB).

If you need your DTI application to have compatibility with machines running previous versions of Pervasive.SQL, then you need to ensure that the functions you use are present in the import library for that version. The reference for each DTI function lists its minimum required import library.

The functions for the Distributed Tuning Interface are documented in Distributed Tuning Interface Reference.

Before Calling Any Functions

When you want to invoke the Distributed Tuning Interface, you must first call the PvStart() function. Then you can call multiple DTI functions before ending the session.

When ending a session, you must call PvStop()to close the session.
