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. -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Morris, Kevin J.

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.
