- Hi Anne,
-
- the PTF-story is a horror story. The design of selective enhancements
- is in priciple a good thing. If you have one or two releases in the year
- and if it would be well documented for what bug each thing it might
- work. But in conjunction with missing QA its a horror.
-
- My company has installed at various customer sites some 200 systems.
- We have seen four levels of aix this year. With every new release
- there were essential bugs. I give some examples:
-
- - with 3.2.0 the Gt1 adapter was introduced, but you could not
- install AIX without VRAM upgrades due to a bug in the installation
- scripts
-
- - the Gt4X adapter had GL problems with 3.2.2 when it was introduced
-
- - you cannot install AIX if you have GT4-adapter, you must have another
- adapter or an ascii terminal, because you have to install 3.2.0 without
- GT4-support and then apply a bunch of PTF's where the GT4 support is hidden
-
- - with 3.2.1 you could not install /usr-clients if you had 150 MB tapes
-
- - the assembler bugfix for gnu-emacs is not incorporated in AIX
-
- - with 3.2.3 you run in serious installation problems with installp procedure
-
- - with 3.2.3 xde (dbx) stops working, qdaemon is buggy, CATIA does not work
-
- So you end up in having large archives of bugfixes to aplly here and then.
-
- The process of the PTF-circus is not managable for large numbers of machines.
- In former times it was a nice feature to have preloaded machines. But
- what is now? You get a machine with minimum OS installed and tons of
- PTF's which must be installed in a long procedure, which may take a day.
- We decided to ignore the preload and to prepare the machines with an
- image installation which take some 1.5 hours.
-
- IBM has to think intensively about the software distribution process.
- One thing is quality assurance. New hardware must be supported in the first
- try not in the second or third upgrade. So they have to slow down their
- emission velocity.
-
- The other thing is that they must consider that to distribute workstation
- software is completly different to VM or MVS patches. I have not to apply
- a few patches on a single processor for thousands of users but thousands
- of patches to thousands of machines.
- The most urgent patches must be available in the net.
- There must be an online database with a bug history available to everyone
- who wants (like other vendors as HP and SUN have it for years).
-
- Did they issue some warnings when 3.2.4 will be available? ;-)
-
- Enjoy,
-
