Using the Optimize Service Option

To create a patch using the Optimize Service option, you first need to publish your packages using the HPCA Administrator Packager or the HPCA Administrator Publisher. For instructions on how to do this, see HP Client Automation Enterprise Administrator User Guide.

Note: Patches can be created for packages that contain a signature only. Initially, only MD5 is supported. Packages being used for patching must be published from the same location, or computer, to qualify for byte-level differencing patching. This will populate the eight-byte Cyclic Redundancy Check (CRC) found in the suffix of the instance names.
As the HPCA Administrator Packager and the HPCA Administrator Publisher calculate and use the MD5 signature, and this signature is vital to the patching functionality, there is no backward compatibility to previously published packages.

This section provides detailed instructions for:

In this example, you will optimize a series of text files called BLD. These files were packaged and promoted to the CSDB. Each text file is its own package in the SOFTWARE Domain.

After you publish your packages to the CSDB, you need to create a ZSERVICE instance.

Caution: In some cases, the difference in size between two packages is so minimal that creating a patch will actually increase the size of the file. In this case, the creation of the patch will not be allowed.

Note: When publishing the files needed for this example, the following naming conventions were used:

By using the same file name and the same machine during publishing, you are assuring the same CRC is needed to correctly create patches.

To configure the Optimize Service feature:

Task 1: "Setup Instances"

Task 2: "Run Service Optimization wizard"

Task 3: "Setup details in File and Progress dialog box"

Task 4: "Build patch and exit Service Optimization wizard"
