I suspect that Linux is a bit heavy to do all the things that CMS does.  And I 
think CMS is used to install Linux (I might be wrong).

It would be nice if Linux could be used to do more VM work.

Subject: Linux guest to manage zVM?


Has anyone considered the possibility of having a Linux guest serve as
the primary means of administering, configuring, and maintaining a z/VM
environment; effectively replacing CMS?  I think Linux could be a much
more powerful and effective environment.  It might also speed
linux-centric shops' adoption as the need for CMS knowledge would be
greatly minimized.
 
Basic advantages of Linux over CMS:
 
  - Linux is a true multi[tasking,programming,processing] environment 
    - unlike CMS where you are limited to one command at a time and
multitasking is emulated via "worker machines".
    - all of the VM system programmers can sign on to the 1 linux guest
opposed to everyone having their own CMS environment
 
  - Linux filesystems are much more user friendly.
    - Two ways to implement:
 1. devise a whole new way for VM config files to reside in an EXT3
filesystem
 2. give the linux guest RW access to all necessary CMS minidisks.
    - Don't have to worry about minidisks filling up
    - Shared R/W filesystems without the complexity of SFS
    - with samba, configuration files could even be edited in your
favorite Windows editor.
 
  - Linux serves as a far superior development environment
    - Access to common high-level languages (perl, java, c++, etc)
    - Automation of any task can be greatly simplified
    - Much easier to "webify" any task or command using
Apache/Tomcat/Websphere.
 
  - Able to take advantage of the vast array of open source tools
 
  - The need for TCPIP and related systems (FTPSERVE, REXECD, SNMPD,
etc) ceases
    - able to use the TCPIP, FTP, SMTP, etc services from linux
    - *can take advantage of SSL for all of these services*!
 

Some basic requirements that would need to be satisfied:
  - Ability to issue CP commands and receive responses (cpint/hcp is a
start)
  - Ability to access CMS minidisks for existing environments (CMSFS is
a start)
  - Ability for linux to act as an 'observer' to OPERATOR and other
various machines and capture/log the data 
    - or better yet, to act as the SYSOPER and handle the messages in an
appropriate fashion.
  - Ability read/write *MONITOR records, communicate with MONDCSS
    - think of the performance monitor tools that could be written in
Linux!
 

I just wanted to throw my initial thoughts on the topic out to the
ListServ to see if anyone else agreed with my perceptions/ideas.
