Re-assembling Applications

After installation, you may need to reassemble your web applications. You need you reassemble in the following cases:

You installed CUE Live using the old-style installation method.
You installed CUE Live using the package-based installation method and your installation includes some old-style JSP-based Escenic publications.

If you installed CUE Live using the package-based installation method and all your publications are based on DPRES, the new decoupled presentation layer, then you do not need to reassemble any applications.

To reassemble your web applications:

Log in as escenic on your assembly-host.
Run the ece script to re-assemble your Content Engine applications
```
$ ece assemble
```
This generates an EAR file (/var/cache/escenic/engine.ear) that you can deploy on all your engine-hosts.
If you have a single-host installation, then skip this step.

On each engine-host, copy /var/cache/escenic/engine.ear from the assembly-host. If you have installed an SSH server on the assembly-host and SSH clients on your engine-hosts, then you can do this as follows:
```
$ scp escenic@assembly-host-ip-address:/var/cache/escenic/engine.ear /tmp/
```
where assembly-host-ip-address is the host name or IP address of your assembly-host.
On each engine-host, deploy the EAR file and restart the Content Engine by entering:
```
$ ece stop deploy start --file /tmp/engine.ear
$ ece restart
```
