NNMSC software development environment SCM
Contents
It is important to keep track of all changes that will be done to
our environments. In case of problems we may identify more easily
possible reasons for them. This is true for both operating system
level (upgrades and patches) and sw development tool level (new
versions of existing software).
Hosts that are used for sw development should be kept identical:
operating system version, patch level, tools installed and their
versions. Hosts used for testing and demonstration purposes should be
very much like future customers will have: no extra tools or patches.
When ever possible with reasonable amount of work every sw tool
should be installed under Clearcase version control. This makes it
possible test new versions of tool without danger and interference to
other designer's work ongoing.
Principles:
- NNMSC System Administrator is
responsible adminstrating and controlling UNIX-operating system
changes.
- Upgrading from one major release to an other means lot of work.
- Many of minor release upgrades can be skipped, required changes can
be usually done by patching.
- Install only necessary patches. Changes are that you brake
something.
- If you download new patches for HPUX, look first
williams:/disc000/Patches directory. Every new patch you fetch
should be copyed to directory mentioned above. That is the
location where to keep patches.
- Beginning from HPUX10 all changes to patch level should be
documented to these www pages.
- These principles apply to all environmets using HPUX10 operating
system and can be applied to other environments later.
Principles:
- NNMSC Asset Manager is responsible for
installing sw development tools and upgrading existing tools to
new versions. Whenever "root" access and account is required
installation should be done together with System Administrator.
- Every tool should be installed under version control. Designers
access tools using proper config specs through UNIX softlinks.
- For easy retrieval of sw media packages used for installation
they should also be installed under version control. This is not
always possible: media will then be kept System Administrators possession.
- Information of tools in use will be documented under these www
pages beginning from HPUX10 version.
