Two instances of Oracle client on one PC

P: n/a
Does anybody know if it is possible to run two different instances
(and potentially different releases) of Oracle client on one Windows
2000 PC? I'd like to do this so that I can have one that I know is
stable, and a second to apply patches and test.

I imagine if I install into 2 different directories the install will
work, but are there any ramifications, such as with ODBC Data Sources
& drivers, etc? After I am done with both installs, what will happen
when I go to Start --> Programs --> Oracle Installation Products?
Which installer will I get?

Note that this is Oracle client only, not server. Thanks,

Bill

Since you have not specified which 2 Oracle versions... I would assume
8i and 9i.

You can install both releases of Oracle client (or server) on the same
machine as long as they are installed in separate homes.

ODBC drivers from both version will show up in the ODBC driver list.

Default Oracle home installer will be used. You can use Home Selector
to change which ORACLE_HOME\bin directory appears first in your
system path.

I did just as suggested, and it seems to be working OK. I have 2
separate Oracle homes, and use the Home Selector to switch between
them. Thanks for the advice Rauf.

Hi Bill,

This all works fine, but gets a little more complicated and irritating slow when you go to Oracle 10g.

I work with Oracle Locator Express, much more easy.
