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.
