Enabling the shared mode for Talend Studio for the first time

The admin user can apply an update, install all features, and enable the shared mode for Talend Studio.

About this task

Only the admin user can enable the shared mode.

Open the corresponding .ini file under the Talend Studio installation directory.
Specify the URLs of the repositories for Talend Studio feature packages and updates by adding the following two lines.
```
-Dtalend.studio.p2.base=<base-url>
-Dtalend.studio.p2.update=<update-url>
```
<base-url> is the URL of the repository for feature packages and <update-url> is the URL of the repository for the update to be applied.
To apply the update and install all features for Talend Studio, run the commandline_upgrade.bat file under the Talend Studio installation directory.
Launch Talend Studio, create a local project and open it.
Relaunch Talend Studio and open the Manage Connections dialog box.
Click Delete Existing Project(s).
In the pop-up dialog box, select the local project you just created and click OK to delete it. This makes the plugins to be fully initialized.
Add or update the following two parameters in the <studio>/configuration/config.ini file:
```
osgi.configuration.area=@user.home/studio/configuration
osgi.instance.area=@user.home/studio/workspace
```
These two properties specify the configuration and workspace locations of Talend Studio for each shared user.
Rename the p2 folder under the Talend Studio installation directory with a new name, p2_bak in this example.
Create the directory <studio>/p2/org.eclipse.equinox.p2.engine/profileRegistry.

After the admin user enables the shared mode, each individual user can get into the shared mode.

Copy the p2_bak folder under the Talend Studio installation directory into the @user.home/studio folder, and then rename the copied p2_bak folder to p2.
Copy the following folders and files under <studio>/configuration into the folder which is defined using the osgi.configuration.area parameter, @user.home/studio/configuration in this example.
- The .settings folder
- The org.eclipse.equinox.simpleconfigurator folder
- The org.eclipse.update folder
- The talend folder
- The config.ini file
Copy the <studio>/license file into the folder which is defined using the osgi.configuration.area parameter, @user.home/studio/configuration in this example.
Launch Talend Studio.
