Yes, it is a bit more difficult to program, but it is infinitely scalable. Of course, you are correct. I took this approach because I have inherited a pre-existing application that used to read a single mainframe dataset. It's only recently that the capability to read multiple files via NFS

No coupling facility, so basic sysplex. XCF signalling via a ESCON CTC. That's all I have. The CF was nixed due to cost. With two systems (which, iirc, you have), simple XCF signalling should be enough. - Too busy driving to stop for gas!
