1. How can I create a LF using crtlf command based on a particular member in a multimember PF? Where I have to specify the member name? 2. How to differentiate between the types of join from a Join logical file DDS. Is it possible to have different types of Join Logical files? 3.Any performance difference between Opnqrf and Embedded SQL? When I should prefer Opnqryf and when SQL? 4. I know access path is the path chosen by the program to retrieve data. It can be of keyed access path or arrival sequence. *IMMED- *IMMED description says access path is updated each time record is added or deleted from a member. - What is updating here? *REBLD - The access path is completely rebuilt each time a file member is opened. The access path is maintained until the member is closed, then the access path is deleted. - I am not able to understand this completely. Could anyone explain these more clearly? 5.What is the purpose of using activation group. I know it is a resource allocator, but other than this any other benefits of using an activation group?
