Types of Releases and Patches
Versions of Serviceguard Extension for RAC are provided as platform releases, feature releases,
or patches.
Platform Release
A platform release is a stable version of the product, which is the preferred environment for the
majority of customers. Platform releases may also contain new features. These releases are
supported for an extended period of time, determined by HP. Patches will be made available
within the extended support time frame even though a newer version of the product is available.
Feature Release
A feature release contains new product features. Feature releases are for customers who desire
to use the latest features of the product. In general, feature releases will be supported until a
newer version becomes available. In order to receive fixes for any defects found in a feature
release after a newer version is released, the customer will need to upgrade to the newer,
supported version.
Patch
A patch to a release is issued in response to a critical business problem found by a customer.
With a patch, the following is guaranteed:
• Patch-specific release testing is performed prior to posting the patch.
• Existing functionality, scripts, etc...., will continue to operate without modification.
• All fixes from the previous patch are incorporated.
For a patch, certification testing is recommended only for those fixes that are important to the
customer.
