Managing Software Cache - Remote Cache

Table of Contents

Overview

When you download updates for each client computer at a time, the network traffic might increase due to multiple downloads running. You can reduce the network traffic through the configuration of a remote cache directory where you can download all required updates just once, and then apply the updates to all the clients associated with the remote cache. The remote cache contents are automatically synchronized with the CommServe® cache contents.

Set Up the Remote Cache

Use the following steps to set up and configure the remote cache directory on a client computer. You can configure more remote cache directories on other clients.

  1. From the ribbon in the CommCell Console, click the Tools tab, and then click Add/Remove Software | Add/Remove Software Configuration.
  2. In the Add/Remove Software Configuration dialog box, click the Remote Software Cache tab and then click Add to configure the remote cache.
  3. In the Configure Remote Software Cache dialog box, complete the following steps:
    1. Click the Computer list and select the computer where you want to configure the remote cache directory.

      The Auto Synchronize with CommServe check box is selected by default to automatically receive the updates from the CommServe software cache when updates are downloaded to the CommServe.

    2. In the Please Specify Cache Directory box, the default location for the remote cache is provided. If you want to specify a different location, click Browse.
    3. Click Add/Remove Clients to associate clients and client groups with the remote cache.
    4. In the Associate Clients/Client Groups to a Remote Software Cache dialog box, under the Available Clients/Client Groups list, select the clients and click Include > to add them to the Selected Clients/Client Groups list, and then click OK.

      The selected clients will receive updates from the remote cache.

    5. Click OK to save your remote cache configuration.
  4. In the Add/Remove Software Configuration dialog box, click OK.

Configuring a Remote Cache to Synchronize Specific Packages

By default, the remote cache fully synchronizes with the CommServe cache, including all packages and updates that reside in the CommServe cache.

To reduce the amount of packages and updates that are transferred from the CommServe cache, configure the remote cache to synchronize only specific software packages.

If you want to configure a new remote cache, see Set Up the Remote Cache and then return to this section.

  1. From the ribbon in the CommCell Console, click the Tools tab, and then click Add/Remove Software | Add/Remove Software Configuration.
  2. In the Add/Remove Software Configuration dialog box, click the Remote Software Cache tab, select the remote cache you want to configure and then click Edit.
  3. In the Modify Remote Software Cache Information dialog box, click Configure Packages to Sync.
  4. In the Configure Packages to Sync dialog box, select Customize Packages to automatically synchronize the following:
    • Updates required for all the associated clients
    • Packages required to upgrade associated clients from older SnapProtect versions

      For example, if you have a Version 9 client, then the remote cache retrieves the latest Version 9 updates along with the Version 10 packages and updates needed to upgrade the client.

  5. In the Configure Packages to Sync dialog box, you can also configure the remote cache to synchronize packages for specific operating systems in addition to the packages that are automatically synchronized. This is useful if you plan to install packages on new or existing clients using the CommCell Console.
    1. Select the operating system from the Select OS list.
    2. From the adjacent list, select the packages.
    3. Click + to specify more combinations of operating system and packages.
  6. Click OK to save your configuration changes.
  7. Click OK to close the Modify Remote Software Cache Information dialog box.

Synchronizing the Remote Cache Contents

By default, the remote cache automatically synchronizes with the CommServe cache when packages and updates are downloaded to the cache. If packages and updates are copied to the cache using the CommCell Console, the remote cache is also synchronized. However, it the copy was made using the CopyToCache tool, the remote cache is not synchronized.

You can manually synchronize the remote cache with the CommServe cache in case the remote cache contents are changed or deleted accidentally.

Use the following steps to manually synchronize the remote cache:

  1. From the ribbon in the CommCell Console, click the Tools tab, and then click Add/Remove Software | Download Software.
  2. In the Download and Sync Cache Options dialog box, clear the Download Updates check box and ensure that the Synchronize Remote Software Caches check box is selected.
  3. Click the Cache Selection tab, and select the remote cache that you want to synchronize with the CommServe cache.
  4. Click OK.

Deleting the Remote Cache Contents

  1. From the ribbon in the CommCell Console, click the Tools tab, and then click Add/Remove Software | Add/Remove Software Configuration.
  2. In the Add/Remove Software Configuration dialog box, click the Remote Software Cache tab, select the remote cache where you want to delete the contents and then click Edit.
  3. In the Modify Remote Software Cache Information dialog box, click Delete Cache Contents.
  4. In the Do you wish to delete Remote Software Cache dialog box, select if you want to delete updates and/or packages:
    1. Click the Delete Update Cache check box to delete all the updates in the remote cache.
    2. Click the Delete Package Cache check box to delete all the packages in the remote cache.
    3. Click OK.
  5. Click OK to close the Modify Remote Software Cache Information dialog box.
