Is it possible to install DB2 7.x and 8.x on one single box (windows/unix)?

I know that multiple instances of the same DB2 version can be had on the same box, with each instance having its own collection of databases.

Similarly, can I have 2 separate installations of the same DB2 version on the same box. The purpose of this is to have different dbm parameters for each installation.

TIA

Hi,
Yes you can have different version of db2 7 and 8 binaries installed on Unix - AIX.
as both sits into different directory structure.
DB2 7.x ---> /usr/lpp/....
DB2 8.x ---> /usr/opt/...

For NT/W2k it is not the case . Only One binary can sit.

I hope this answers your question.

Can you point me to doc for DB2 multiple version installations on a single unix box.

Hi ,

Sorry I am unable to get the doc , but I had worked with multiple version of db2 in my previous assignment.

I myself had installed both version on AIX DB2 7.2 + FP 8
and DB2 8.1 + FP2 but at this time I am helpless to find any doc related to that.

You can have both DB2 V8 & V7 on the same box and both instances running at the same time, just remember that your biniaries will take up allot of memory. You'll have 2 copies of db2 in memory instead of 1. We currently have a bunch of systems that are a mix. We also multiple system that are running more that one instance on the same box.
