Enable the RepAgent feature on the Adaptive Server using sp_configure. You need to perform this task only once at each Adaptive Server.
Log in to Adaptive Server and enter this command at the isql prompt:
sp_configure 'enable rep agent threads', 1
sp_configure 'enable rep agent threads' is a dynamic option. It takes effect immediately. However, you may want to restart Adaptive Server after enabling RepAgent so that Adaptive Server allocates a fixed number of dedicated static process structures for the thread. Otherwise, RepAgent borrows process structures from the pool dedicated to user connections.
