Learn about the upgrade process using the sybcluster utility,
and preupgrade tasks to complete before upgrading your old server. You can also perform a manual
upgrade to the Cluster Edition. See
the Manually Upgrading topic for how to do this.
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.
Before you start the upgrade:
- Back up
old databases.
- Install the Cluster Edition. Make sure that the
nonclustered Adaptive Server that is to be upgraded and the Adaptive
Server Cluster Edition version 15.5 installation directories are
located on the same machine. This is the upgrade machine.
- Review the Creating and Starting the Cluster topic and the Worksheet for creating a cluster for a list of the information you
need for the upgrade.
Complete
the tasks before you upgrade your server.
- See the Verifying the Server for Upgrade topic to make sure that your server
is ready for upgrade.
- See the Upgrading Your Old Server With sybcluster topic for how to upgrade the server
to Adaptive Server Cluster Edition version 15.5.
- Perform the postupgrade tasks
after the upgrade, whether you upgrade the server manually or use sybcluster.
