Chapter 12 Performing Administrative Tasks for the Proxy Cache Service and Array

• "Modifying Your Configuration"

• "Backing Up Your Configuration"

• "Restoring Your Configuration"

This chapter describes additional configuration procedures not described in the Netra Proxy Cache Array Configuration Guide or the Netra Proxy Cache Server Configuration Guide.

The starting point for most performing most proxy cache- and array-related tasks is the Proxy Cache Administration page. See Chapter 3, Loading the Proxy Cache Administration Page," for instructions on bringing up this page.

Modifying Your Configuration

Use of the "basic" links in the Proxy Cache Administration page to modify your Netra Proxy Cache Server or Array configuration is the same as it is for first-time configuration, and is described in the Netra Proxy Cache Array Configuration Guide and the Netra Proxy Cache Server Configuration Guide.

Advanced configuration is described in Chapter 4, Advanced Proxy Cache Configuration for the proxy cache service.

When making changes to proxy cache service or array properties, the significant points to keep in mind are:

• For a server, if you make any changes to the proxy cache service properties, you must install those changes before they take effect.

• For an array, if you make any changes to the proxy cache service or array properties, you must install those changes on all hosts in the array (including the administrative host).

• If you make any changes to an array member configuration, you must install the changes on the modified host.

You install changes using the Install Configuration link in the Proxy Cache Administration page.

Backing Up Your Configuration

You can backup your server or array configuration by using the Save/Restore link in the Netra Main Administration page. See Chapter 3 of the Netra Proxy Cache Array Configuration Guide or Netra Proxy Cache Server Configuration Guide for a detailed procedure.

Restoring Your Configuration

Assuming you have backed up your configuration to diskette (see preceding section), you can restore that configuration, to an individual server or to all of the hosts in your array. Use the Save/Restore link in the Netra Main Administration page.

If you suffer a complete failure, such as the loss of the hard disk from which you boot, follow the procedure in Appendix A, System Recovery."

To Restore a Proxy Cache Configuration

1. Insert your backup diskette in the diskette drive of the host being restored.

2. In the Netra Main Administration page, click Save/Restore.

3. In the Save/Restore page, click Restore configuration from diskette.
