What is difference between installing Java in HFS or zFS
Posted: Sat Feb 27, 2016 7:27 am
The context: I am installing for the first time Java in mainframe Z/OS 390. I am about to follow the procedures found in "SDK8_64bit_readme.txt". There is certain step which states:
(4) Create an HFS or zFS filesystem dataset into which you'll later expand
the pax file. Mount this filesystem at: /usr/lpp/java/Jv.r{_64}
Sorry for analogy with Windows but I am really new on mainframe: in Windows we never ask ourself which filesystem to use, I mean it wouldn't make sense to think "should I use FAT32 or NTFS". It wouldn't make sense since the entire drive is only one type. If I understood correctly, I am choosing between two types of filesystem, HFS or zFS. So my dummy question is: should I be aware about any possible difference if I choose HFS or zFS? When I open "Command Prompt" via OMVS or iShell command, browse to certain folder, and type mkdir, am I creating a HFS or zFS folder?
