To upgrade from a noncluster Adaptive
Server to the Cluster Edition, perform preupgrade tasks, then upgrade using the sybcluster utility. If you already have a clustered Adaptive
Server, upgrade manually.
The command line-based sybcluster
utility allows you to create and manage a cluster. The utility uses the SCC Agent
Framework to "plug in" to the Sybase Control Center remote command and control agent on
each node in the cluster. The SCC agent processes the sybcluster commands that let you manage the cluster. See the Users Guide to Clusters for detailed information about
sybcluster, and the Sybase Control Center
for Adaptive Server for the SCC Agent Framework.
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 15.7 installation directories are
located on the same machine. This is the upgrade machine.
- Review how to create and start a cluster, and prepare your worksheet for a list of the information you
need for the upgrade.
Complete these tasks before you upgrade:
- Make sure that your server
is ready for upgrade.
- Upgrade the server
to Adaptive Server Cluster Edition version 15.7.
- Perform the postupgrade tasks
after the upgrade, whether you upgrade the server manually or use sybcluster.
