This section describes the upgrade process using the sybcluster utility. sybcluster performs many of the upgrade steps for you. You can also upgrade to the Cluster Edition by performing all the upgrade steps yourself. See “Manually upgrading to the Cluster Edition”.
sybcluster is a command line–based utility that allows you to create and manage a cluster. sybcluster uses the Unified Agent Framework (UAF) to “plug in” to the Unified Agent on each node in the cluster. The Unified Agent processes the sybcluster commands that let you manage the cluster. See the Users Guide to Clusters for detailed information about sybcluster and the UAF.
This section describes three task sets for upgrading your server:
Before you begin – complete these tasks before you upgrade your server.
Verifying the server for upgrade – make sure that your server is ready for upgrade.
Upgrading the server – upgrade the server to Adaptive Server Cluster Edition version 15.0.1 ESD #4.
In addition, after completing the upgrade, perform the tasks described in “Post-upgrade tasks”. These tasks must be performed whether you upgrade the server manually or using sybcluster.
