Re: Information on data movement out of z/OS using Zowe and other platforms

Onno Van den Troost

A Google search for "z/OS big data" comes up with some interesting links to avoid moving the data for off-platform processing.

I know this sounds like a sales pitch, but IBM offers multiple methods of running non-Z software inside a Z box; zCX, zLinux flavors and zBX blade (hardware) extensions with non-Z processors. I'm not sure on the details of how far IBM got with data sharing between these and your z/OS. But even if there is no sharing, you'll have the benefit of improved I/O performance if the data stays in the box. Your local IBM rep can work with you to fill in the details and see if this is a good fit for you.

Hello John,

The first question I'd ask is "Do you really have to move the data off the mainframe?"  In-situ processing of high data volumes is a fruitful research area, particularly in high-performance computing.  With Zowe's REST API capabilities, you might want to consider running the application that consumes the mainframe data ... on the mainframe itself.  Applications written for Linux and Node.js will already run on z/OS, so it's something I'd throw into the mix.

Also, in-situ is more future-proof, since I/O bandwidth trends generally lag behind processor power.

Are there any projects built to support non-TCP based bulk data transfer of flat files, PDS, VSAM, and DB2 change logs, out of the mainframe?
We are already looking to adopt Zowe for lot of our z/OS work, but we also have high performance reporting and analytics requirements for which we need to get data out of the mainframe.
