Comments interspersed w/<> 1) Unix Systems Services for the masses - today no one outside of tech services can get to unix command prompt. I suspect developers will need their own filesystems, etc. Don't want to make it complicated or require a lot of administrative overhead. Security?
<I am going through this now. Read Chapter 17 of the z/OS 1.13 RACF Sec Admin Guide. I have found that if you set up AUTOUID processing this becomes very easy to do. No work to add UNIX prompts to the masses. Set up the proper defaults and the RACF OMVS segment will be automatically generated the first time they use *ANY* OMVS services (includes FTP). Security will be provided at the UNIX level based on the OMVS UID/GID assigned.> I suspect developers will need their own filesystems, etc. Don't want to make it complicated or require a lot of administrative overhead. <The "normal" default is to place a default home directory of /u/racfuid for each user. Each user with a need will receive his own ZFS and it will be handled with UNIX automount which works in conjunction with SMS and HSM.> 2) Isolating JAVA release levels from applications. Is this possible? We tend to keep several versions of JAVA available(1.4, 5,6, and 7) but make the most current, the "default" as in the path in JAVA_HOME. What I don't want is applications coding for specific versions(if possible) causing upgrade nightmares. <Each version of JAVA comes in its own HFS/ZFS. Should be easy to do. This would typically be a read-only filesystem. JAVA_HOME can be set at "default", user, or script level and changed at any time. If you don't have it already, get a copy of UNIX SHELL PROGAMMING, Kochan/Wood, Hayden Books. Should be available at any "good" bookstore/college bookstore.> 3) Shared file systems. Today we do not share filesystems for read/write across the lpars in our sysplex. We share sysres filesystems readonly. Filesystems for write access are system specific today. <I suggest SYSPLEX sharing of HFS/ZFS.
