Hi, I want to create alternate index on VSAM file.my file structure is ex: RoomID pic x(7) R000001 Floor pic a((6) First RoomNo pic x(2) FA1 Occupied(yes/no) pic a(3) Yes Occupied Batch pic x(10). Maths i want to create alternate index on floor,roomno fields.can i create alternate index on both the fields.and tell me how to create.
Yes. Because the alternate key would first locate the primary key, which in turn locates the actual record. Needs twice the number of I/Os.
