Uninstalling the Bridge

To make sure the Bridge will be uninstalled correctly, read the description carefully, as there are significant differences between

wanting to remove a Bridge instance from a multiple Bridge installation and
wanting to remove a Single Bridge installation.

You need administration rights to perform the steps described below.

Stopping the Services and the Bridge

Stop all running services on the Bridge.
If a deployed service was using a proxy, stop the Proxy Server in the Bridge.
Stop the Windows service/Linux daemon of the Bridge (E2E Console) on the system.

On Linux systems, you need to login as root user and execute the following command:

CODE

/etc/init.d/e2e_console stop <DNS name>

Manual Removal of a Single Bridge Installation

Follow the steps below to remove a Single Bridge Installation or the last server instance of a Multiple Bridge Installation.

Removing a Single Bridge Installation

Removing the Directories
- Remove the installation directory of the Bridge (default location: C:\E2E_BRIDGE_PROG resp. /opt/e2e_bridge_prog).
- Optionally, remove the data directory of the Bridge containing the composite services (default location: C:\ E2E_BRIDGE_DATA resp. /opt/e2e_bridge_data).
  If you decide to not remove the data directory, you need to remove the following files from this directory:
  - data.properties
  - domain\nodes.xml
  If these files are not removed, and you try to re-install the Bridge, the installer will use the old installation parameters and perform an update installation.
Removing the Registry Entries (Windows only)
- With a installation in workstation mode, use a command shell to remove the following registry entries:
  NONE
```
sc.exe delete E2EConsole-localhost
sc.exe delete E2EProxies-localhost
```
- With a installation in server mode, use a command shell to remove the following registry entries:
  NONE
```
sc.exe delete E2EConsole-<fully qualified domain name>
sc.exe delete E2EProxies-<fully qualified domain name>
```
  For example:
  NONE
```
sc.exe delete E2EConsole-bridge.scheer-acme.com
sc.exe delete E2EProxies-bridge.scheer-acme.com
```
  Look at the Windows Services dialog for your fully qualified domain name.

Removing the Files (Linux only)

Remove the Bridge startup file.
Remove the following links to the startup file.
These links are used for the start of the Bridge service on system startup.

If you did not check the option Start E2E Bridge service on system startup during the installation of the Bridge, these links were not created by the installer.

In each folder rc2.d and rc3.d, there are two files starting with letter K or S, followed by a number and e2e_console. However, the number (here 99) may be different as they were generated by the operation system. Make sure to remove all four files.

/etc/rc0.d/K99e2e_console
/etc/rc1.d/K99e2e_console
/etc/rc2.d/K99e2e_console
/etc/rc3.d/S99e2e_console
/etc/rcS.d/K99e2e_console

Remove the file /root/.e2econsole, if existent. This file comes from older Bridge versions.

Removing Bridges from a Multiple Bridge Installation

Follow the steps below to remove an additional Bridge from a Multiple Bridge installation.
If you are removing the last Bridge instance of a Multiple Bridge Installation, refer to section Manual Removal of a Single Bridge Installation.

Removing an additional Bridge from a Multiple Bridge Installation

Editing the Files (Linux only)

Edit the Console startup file /etc/init.d/e2e_console as follows.
Locate the lines that define CONSOLE_HOSTNAMES and CONSOLE_HOMES, for instance:

CODE

CONSOLE_HOSTNAMES="bridge.scheer-acme.com bridge2.scheer-acme.com"
CONSOLE_HOMES="/opt/e2e_bridge_prog /opt/e2e_bridge_prog2"

Remove the entries for the node you want to remove, for instance bridge2.scheer-acme.com, which is installed in folder /opt/e2e_bridge_prog2.
After editing the file, both lines would look like this:

CODE

CONSOLE_HOSTNAMES="bridge.scheer-acme.com"
CONSOLE_HOMES="/opt/e2e_bridge_prog"

Removing the Directories
- Remove the installation directory of the Bridge (default location: C:\<program directory of the bridge>).
- Optionally, remove the data directory of the Bridge containing the composite services (default location: C:\<data directory of the bridge>.
  If you decide to not remove the data directory, you need to remove the following files from this directory:
  - data.properties
  - domain\nodes.xml
  If these files are not removed, and you try to re-install the Bridge, the installer will use the old installation parameters and perform an update installation.

Removing the Registry Entries (Windows only)

Use a command shell to remove the following registry entries:

NONE

sc.exe delete E2EConsole-<fully qualified domain name>
sc.exe delete E2EProxies-<fully qualified domain name>

For example:

NONE

sc.exe delete E2EConsole-bridge2.scheer-acme.com
sc.exe delete E2EProxies-bridge2.scheer-acme.com
