7.1 Adding Proxy Settings for Oracle Private Cloud Appliance Updates

If your data center does not provide unlimited internet access and has a proxy server in place to control HTTP, HTTPS or FTP traffic, you may need to configure your management nodes to be able to access external resources for the purpose of performing software updates.

The following instructions must be followed for each of the two management nodes in your environment.

Adding Proxy Settings for a Management Node

Gain command line access to the management node. Usually this is achieved using SSH and logging in as the root user with the global Oracle PCA password.
Use the CLI, as described in Chapter 3, The Oracle Private Cloud Appliance Command Line Interface (CLI), to view or modify your proxy settings. The CLI safely reads and edits the /etc/ovca.conf file, to prevent the possibility of configuration file corruption.
- To view the current values for the configurable settings in the configuration file run the CLI as follows:
```
# pca-admin show system-properties
```
- To set an HTTP proxy:
```
# pca-admin set system-property http_proxy http://IP:PORT
```
  Where IP is the IP address of your proxy server, and PORT is the TCP port on which it is listening. If your proxy server expects a user name and password, this can be specified in the following format:
```
http://username:password@IP:PORT
```
- To set an HTTPS proxy:
```
# pca-admin set system-property https_proxy https://IP:PORT
```
- To set an FTP proxy:
```
# pca-admin set system-property ftp_proxy ftp://IP:PORT
```
Setting any single parameter automatically rewrites the configuration file and the proxy settings become active immediately.
