After the loadmanger performs validations for session,it
creates the DTM process.DTM is to create and manage the
threads that carry out the session tasks.I creates the
master thread.Master thread creates and manges all the other
threads.\
DTM process: The Load Manager creates one DTM process for
each session in the workflow. it performs the following
tasks:
• Reads session information from the repository.
• Expands the server, session, and mapping variables
and
parameters.
• Creates the session log file.
• Validates source and target code pages.
• Verifies connection object permissions.
• Runs pre-session shell commands, stored procedures
and SQL.
• Creates and run mapping, reader, writer, and
transformation threads to extract, transform, and load
data.
• Runs post-session stored procedures, SQL, and shell
commands.
• Sends post-session email.
