Sun OTP Patch Clusters

Patch clusters are the consolidation of all Sun OTP and OTP-relevant component product packages and patches that are required for maintenance and maximized solution stack stability. All fixes for Sun OTP will be released as patch clusters. You can install patch clusters using both the CLI and N1SPS interfaces.

Sun OTP is a single unified solution stack consisting of integrated component products. Change management for the Sun OTP solution stack involves consolidating individual component product fixes into Sun OTP patch clusters and qualifying those patch clusters as a unified sets of change. Individual patches for constituent component products should not be used. Changes to a Sun OTP solution stack will be made through rigorously qualified patch clusters.

The patch clusters handle complexities such as dependencies, installation order, special instructions, reboots and reconfiguration, single user and multi-user modes.

Following are the two types of patch clusters:

• Critical patch cluster - A critical patch cluster includes fixes that are critical to the proper functioning and operation of Sun OTP. Critical patch clusters are time-sensitive and will be released periodically.

• Maintenance patch cluster - A maintenance patch cluster is the consolidation of component product fixes released on a periodic basis.
