- Part 6: 1003.7

- 1003.7 - System Administration
-
- At the first official meeting of the 1003.7 working
- group, John Quarterman presented a USENIX concern about the
- direction that the working group seemed to be taking.
- USENIX was concerned about the "single machine" model which
- was being suggested by the working group for designing tools
- and utilities. USENIX felt that if a single machine model
- where used, it would be difficult or impossible to extend
- the utilities and interfaces adopted by the committee to a
- networked system. However, if the working group chose a
- model in which a machine was assumed to be part of a tightly
- coupled network, then a single stand-alone machine could be
- a simple special case of a networked machine.
-
- After some deliberation, the working group adopted the
- USENIX model of a machine in a tightly coupled network.
- This has some rather far-reaching implications on the
- direction of the working group, as it is a different
- approach than that taken by 1003.1 and 1003.2. It will also
- mean that the group will be relying heavily on work and
- expertise from 1003.8 (networking). It also means that some
- of the concepts, such as a filesystem, which we thought we
- had a definition for, suddenly become much more complex.
-
- In addition, it means that the working group will be
- reviewing several documents which reflect prior art in the
- area of networking, such as the CMIP, ASN.1 and SMNP
- networking protocols. These protocols will be reviewed at
- the next meeting.
-
- A number of areas are affected by networking
- implications. Some of these are difficult to resolve, since
- things like device management, print spooling and
- performance monitoring, to name a few, may want to cross a
- network. The working group is still undecided about the
- direction which is going to be taken here. The two obvious

- options are to provide for centralized administration of a
- network of machines, allocating and deallocating devices
- over the network from central spot; or a decentralized model
- in which each machine in responsible for administering the
- devices connected to it. This will be reviewed at the next
- meeting.
-
- Although this was our first meeting, a substantial
- amount of work was done by the working group. The first two
- days were spent reviewing global issues to the working
- group, such as determining direction, reviewing IEEE
- procedures, discussion of previous informal meetings of the
- system administration group and discussion of which model to
- choose. Once all of this was done, the working group split
- up into small groups and focused on the areas which needed
- to be addressed. Specifically, the areas being addressed
- are:
-
- 1. Process Management
-
- 2. Spooling Management
-
- 3. System Startup/Shutdown
-
- 4. Communication Management
-
- 5. File Systems Management
-
- 6. Performance Monitoring
-
- 7. System Accounting
-
- 8. Device and Media Management
-
- 9. Software Management
-
- 10. User Administration
-
- 11. System Monitoring
-
- 12. Miscellaneous
-
- 13. Introduction
-
- Some items of note:
-
- Spooling Management
-
- The System V spooling mechanism was chosen as a model
- for the working group. This model has been adopted by
- X/Open. It was recognized by the working group that the

-

-
- current System V lp interface does not adequately support
- networking. The working group felt that it could be extended
- to support networking relatively easily.
-
- Communications Management
-
- The committee will review the CMIP, ASN.1 and SMNP
- protocols to determine if and how these protocols may fit
- into the work that the working group is doing. In addition,
- UUCP managed to rear it's (useful but ugly) head here. Even
- though 1003.2 has parts of UUCP within its scope, this
- committee may need to address the issues of UUCP
- administration.
-
- File System Management
-
- The biggest problem here will be defining what a file
- system really is. 1003.7 will be looking to 1003.8 for help
- in defining the concept. However, the group has realized
- that even without a definition it will be useful to be able
- to mount, unmount and check file systems.
-
- Performance Monitoring
-
- The performance monitoring group has followed the lead
- of the /usr/group performance monitoring committee. This is
- hardly surprising considering that the technical reviewer
- for this section is the chair of the /usr/group performance
- monitoring committee. Their model seems reasonable, and in
- fact represents prior work in this area.
-
- System Installation
-
- An inordinate amount of time was spent drafting an
- objection to the AIU facility described in 1003.2. The
- object will be submitted to 1003.2 as an objection from the
- 1003.7 working group. There are a number of concerns about
- the application installation which many in the working group
- and outside of it feel are not able to be addressed by a
- rigidly-defined installation utility. Work progresses in
- spite of these concerns.
-
- The working group submitted a substantial amount of
- work to the technical editors. The editors have now
- collated all of this information and produced a draft that
- will be discussed at tha April meeting. Although this
- document may not be suitable for release, it will at least
- provide a framework for development for the working group.
-
- Obviously, the work has just begun, but so far a fair
- amount of progress has been made, and hopefully, more
