Updating Zend Core

Users who have purchased a Zend Core Support Subscription (Silver, Gold or Platinum) can get periodic Zend Core Updates, including bug and security fixes.

For more on Zend Support programs, and to register, see the Zend Core Support page at http://www.zend.com/en/products/core/support.

Note:

Updates and Zend Update Packages are only available to Zend Core Subscribers. By downloading Zend Core for i5/OS, you receive a three year, first-level Silver Support Subscription commencing on the date of the first Zend Core for i5/OS download by someone at your company.
If you are updating online, you must therefore ensure that your correct Zend Core Support Subscription User ID and Password (or Zend account login details) are configured in Zend Core. To configure these settings, open the Zend Core Setup Tool and select Update via Zend Network Menu | Change Network ID user/password.

There are two ways of downloading and installing these Updates:

1. Updating Online - Download and install one or more Updates. Updates can be downloaded and installed using the Zend Core Setup Tool.
   This method is only applicable for systems with a direct internet connection..

2. Updating Offline - Download a Zend Update Package, containing one or more Updates, from the Zend Network Update site (http://www.zend.com/en/products/core/updates). The Zend Update Package can then be installed through the Zend Core Setup Tool Zend. This method is useful for closed environments.

1. Updating Online

This procedure describes how to download and install Updates using the Zend Core Setup Tool.

2. Updating Offline

This procedure describes how to update Zend Core by downloading Zend Update Packages from the Zend Network site and transferring them to your system using the Core Setup Tool.

Note:

Windows authentication requires you to be connected to the internet when installing Zend Update packages.

Note:

It is recommended to test the Updates on a test environment before applying them to a production environment.

Consistency Checking

The Zend Core Setup Tool performs consistency checks to prevent you from installing Updates which are dependent on other, uninstalled Updates.

However, if necessary you can force the download of these Updates through the Zend Core Setup Tool. (Not recommended.)

Rollbacks (Removing previous Updates)

Update transactions are preserved so that Updates can be removed and the system can be 'rolled back' to a previous state. This action is referred to as a Rollback. Rollbacks are stored and displayed with the date and time that your system was modified and Updates installed. Selecting a Rollback will revert your system back to the state it was in on the selected time/date.

This procedure describes how to execute a Rollback to a specific recent system state, using the Zend Core Setup Tool.

Note:

Rollback information is stored so that your system can be restored to a previous state.
Two parameters have been defined to ensure that the rollback feature consumes the least disk space possible:
1. Maximal disk space allocated for backups (Default maximum disk space consumption = 100Mbytes).
2. Only the last ten update transactions will be stored, provided they do not exceed 100Mbytes.
In addition, you can choose to delete Rollback information (see below).
