Install a Load Balancer and Prepare Configuration Templates (Windows)

The CA Process Automation installation media includes the following sample configuration file for the Apache load balancer that you can use as a starting point for configuration:

ApacheConfig.zip

The following instructions assume that an Apache 2.2 load balancer is dedicated to CA Process Automation. First, install an Apache load balancer. Then, extract files from the CA Process Automation ApacheConfTemplates zip file to the Conf folder under the Apache installation folder.

Follow these steps:

Log in to the host where the load balancer is to run.
The load balancer typically is not on the same host as your Domain Orchestrator. However, the host with your Domain Orchestrator must be routable from the load balancer.
Download and install the latest Apache load balancer with SSL support. Follow the vendor instructions.
Download the following file for the Apache version that you installed:
```
mod_jk.so
```
We recommend that you download the latest version.
Copy the mod_jk.so file to the following folder:
```
apache_install_dir\modules
```
Navigate to the following folder on the CA Process Automation installation media:
```
install_dir\DVD1\ApacheConfTemplates
```
Extract the following files from ApacheConfig.zip:
```
mod-jk.conf
```
```
httpd-proxy.conf
```
```
uriworkermap.properties
```
```
workers.properties
```
```
httpd VIRTUALHOST_EXAMPLE FILE
```
Note: The extracted httpd VIRTUALHOST_EXAMPLE FILE file contains text you can cut and paste into the Apache httpd file when you configure secure communications. The required text is also in the documentation.
Copy the following extracted files to the apache_install_dir\conf folder:
```
mod-jk.conf
```
```
httpd-proxy.conf
```
```
uriworkermap.properties
```
```
workers.properties
```
Note: If you do not have an Apache 2.2 load balancer to dedicate, merge the configuration information in the example template properties and Conf files into your existing files. As a precaution, back up your files before you modify them.
