Associate an Instance with a Different Installation (Upgrade or Downgrade)
You can use the ttInstanceModify -install option to associate the instance with a different TimesTen installation. This is typically used to upgrade the instance to a new maintenance or patch release. It cannot be used to upgrade to a new major release (such as going from 22.1 to 26.1).
This example upgrades from the ttinstall installation to the ttinstalllatest installation. The current directory is timesten_home for the ttuser1instance instance.
Optional: Before running $TIMESTEN_HOME/bin/ttInstanceModify, you can review the timesten_home/install directories and files to gain an understanding of the symbolic links that are defined.
Navigate to the timesten_home/install directory and run the Linux ls -l command to list the directories and the files within this directory. Note that symbolic links to the installation directory are defined for most of the files and the directories within this timesten_home/install directory. (In this example, swdir/TimesTen/ttinstallations/ttinstall/tt26.1.1.1.0 is the installation directory.)
% cd timesten_home/install
% ls -l

Now run $TIMESTEN_HOME/bin/ttInstanceModify -install to associate the ttuser1instance instance with the new installation (/swdir/TimesTen/ttinstallations/ttinstalllatest/26.1.1.2.0, in this example).
% $TIMESTEN_HOME/bin/ttInstanceModify
/swdir/TimesTen/ttinstallations/ttinstalllatest/26.1.1.2.0
Instance Info (UPDATED)
-----------------------
Name: ttuser1instance
Version: 26.1.1.2.0
Location: /swdir/TimesTen/ttinstances/ttuser1instance
Installation: /swdir/TimesTen/ttinstallations/ttinstalllatest/26.1.1.2.0
Daemon Port: 21000
Server Port: 21001
The instance ttuser1instance now points to the installation in
/swdir/TimesTen/ttinstallations/ttinstalllatest/26.1.1.2.0
After running ttInstanceModify, note the symbolic links within the $TIMESTEN_HOME/install directory point to the new installation directory.
% cd $TIMESTEN_HOME/install
% ls -l
