 IDS.2000 and IDS 7.31 on one unix box

Hi,
as mentioned earlier in this list I probable will be
forced to install IDS.2000 on my Reliant Unix box
when the port is available.

On the same box are running some applications
which cannot been migrated to IDS.2000 in a
short time. They actually run under IDS 7.31UC2.

The new application needs IDS.2000 because of its
ability to work with long identifiers.

My questions: Is it possible and advisable to install
this two versions of IDS and operate them as
two instance?

Has anybody experience with this?

Any suggestitions will be appreciated.

Reinhard

No problems, you install in different directories and set INFORMIXSERVER
and INFORMIXDIR. It's smart to set ONCONFIG and INFORMIXSQLHOSTS to
so you can share some directoties between your instances.
We have three instances on one machine, one beeing a HDR secondary.

The hard part is tuning, your carfully (?) tuned instance is now
beeing affected by the new instance...
More cpu's, disk and memory normally takes care of those problems.
You should at leaste figure out how much resources you're asking
for and what that does to the machine.

Copying between instances is also a chapter missing in the manuals.
You can either "create database, fill it with data, create indexes and
run update statistics" or use dd to move the data and relative links to
keep Informix happy.

Greg Dewinter suggested the dd-part, and Art S. Kagel told me not to;)
-Relative paths are bad
