Hi,

What is the use of DBCTL in IMS DB?

Does DBCTL defines the database? We have 3 DBCTL in production but in previous it was only one. What is the benefit of having more than one of them? I read about it but don't understand it. Can someone please guide?

What is the benefit of having more than one of them?
