Two DB2 copies running at the same time

Is it possible to have two DB2 copies running concurrently? According to IBM, it is possible, but they don't say how.

I'm running on a Windows server 2008 r2.

First and default one's DB2 version is V9.7.400. The second one that I want to add will be 11.1.0.

I can see both copies and I know they run, but I can't get them to run at the same time.

DB2 copies with instances

One of them is running, because I can check from the application. When I try to start the other data studio lunched the command, but keeps hanging.

When I try to create new database on the second copy, I get an error:Error from creating database

Solution

  • To have more than one Versions of DB2 running you have to install both versions of the product and have an instance for each installation. During the installation choose "Install New".
