RE: What is DTM session

The DTM process - Creates threads to initialize the session read write and transform data and handle pre- and post-session operations

DTM process is the second process associated with a session run

The primary purpose of the DTM process is to create and manage threads that carry out the session tasks

The DTM allocates process memory for the session and divides it into buffers. This is also known as buffer memory

It creates the main thread which is called the master thread

The master thread creates and manages all other threads

If you partition a session the DTM creates a set of threads for each partition to allow concurrent processing

When the Informatica Server writes messages to the session log it includes the thread type and thread ID
