Add a language pack to Maximo

Adding a language pack to Maximo after having installed it can be done by running the installer again. After few dialogs and some checks you will be prompted with a list of languages that can be added to the base language.
Alternatively you can follow the manual procedure described hereafter.

First of all you have to install the language pack using the Process Solution Installer.

1. On the administrative workstation, launch the Process Solution Installer (PSI): Click Start > Programs > IBM Tivoli base services > Process Solution Installer.
2. On the Choose PSI Package panel pick the desired language pack in [SMPDIR]\pmp directory. For example, to install italian language pack I have selected D:\IBM\SMP\pmp\PAE_Lang_Pkg_7.5.0.2_It.zip file.
3. Provide the required middleware credentials and start the installation.

Now you can add the language for use with the product using the TDToolkit. Open a command line and move to [SMPDIR]\maximo\tools\maximo directory. Launch the following command specifying the correct locale you want to install.

TDToolkit.bat -ADDLANGlocale -maxmessfix

You may need to restart the Maximo server.
