To upgrade from a noncluster Adaptive
Server to the Cluster Edition, perform preparatory tasks, then upgrade using the sybcluster utility.
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 SP100 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 information you need for the upgrade.
Before you upgrade:
- Make sure that your
server is ready.
- Upgrade the server to Adaptive Server Cluster Edition version
15.7 SP100.
After upgrading, whether manually or using
sybcluster, perform
the postupgrade tasks.
