Modifying a TimesTen Client Instance
The ttInstanceModify
utility modifies the attributes of the instance. The relevant ttInstanceModify
options for a client instance are the -install
and the -tnsadmin
options.
The client instance that is modified is the instance that the $TIMESTEN_HOME
environment variable references. Ensure you run the ttInstanceModify
utility from the $TIMESTEN_HOME
/bin
directory.
See ttInstanceModify in the Oracle TimesTen In-Memory Database Reference for more information.
These sections illustrate how to use the ttInstanceModify
:
Use the ttInstanceModify Utility Interactively
This example runs ttInstanceModify
interactively. The utility asks if you want to change the installation that the instance points to. This is equivalent to running ttInstanceModify
with the -install
option.
This example upgrades from the ttinstall
installation to the ttinstalllatest
installation. The current directory is timesten_home
for the clientmac
instance.
% $TIMESTEN_HOME
/bin/ttInstanceModify
