Direct and indirect requests

A direct request is a requested operation where subscription names are fully or partially specified. For example, the following CDC Replication console commands are direct requests:

MODIFY <Address_Space_Name>,ENDTSMIR,SUBSCR=(PRODSUB),CNTRLD

MODIFY <Address_Space_Name>,ENDTSMIR,SUBSCR=(PR*),IMMED

In the first example, the full name of the subscription is specified. In the second example, the wildcard character is used to select all subscriptions that have names starting with the characters PR.

An indirect request is a requested operation where subscription names are not fully or partially referenced. For example, the following CDC Replication console command is an indirect request:

MODIFY <Address_Space_Name>,ENDTSMIR,SUBSCR=ALL,CNTRLD

In the example, a predefined value (ALL) is used to reference all subscriptions defined in the CDC Replication address space regardless of their names.
