Re: DLF and Hiperbatch

Hi, In the 90's and early 2000's i worked for a company that used Hiperbatch with a significant performance boost in batch processing. I don't think is a viable choice anymore, mainly because of Sysplex processing and the evolution of storage subsystems. Best Regards Ituriel do Nascimento

DLF and Hiperbatch

While working at multiple sites I have seen customers activating the DLF address space often. DLF supports a facility known as Hiperbatch, which was introduced in the early 1990s. Hiperbatch is a way of making data available in expanded storage from one job step of a batch job to another job step,

My advice is to abandon the horrible Web Enablement services and build a good C JSON parser like json-c. Even better if you can ditch C and use C++ because then you have some very nice options. https://github.com/json-c/json-c https://github.com/nlohmann/json On 13/3/23 18:07, Robin Atwood

You don't need to write a large block but you do need to construct both a BDW and an RDW. The length in the RDW should be 5 (control character plus RDW) than the length of the text, and the lenght in the BDW should be 4 more than that.. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3
