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available within the extended support time frame even though a newer
version of the product is available.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.
