If you set up the cluster manually, you cannot use the Adaptive Server
plug-in or sybcluster to manage your cluster until you
create and deploy the Sybase Control Center agent.
Setting the Environment
Set your Sybase environment. From the Sybase release directory, source the SYBASE.sh or SYBASE.csh file.
Raw Devices
Each raw device must be accessible from each node using the same path. See your operating system storage administrator or documentation for help in setting up raw devices.
The Cluster Input File
Before configuring the cluster, create a cluster input file that specifies the name of the cluster, the number of instances in the cluster, the path to the directories containing the interfaces file, log files, quorum disk devices, and other required configuration information. Choose any name for the cluster input file (for example, mycluster.inp).
Manually Configuring the Cluster
Sybase strongly recommends that the total number of engines in all instances does not exceed the number of CPUs.
Reconfiguring the Cluster
You can reconfigure a cluster to add instances, change trace flags, and so on. Edit the cluster input file, then create a new run file for the instance you intend to start first and that includes the dataserver with the cluster-input option. This option tells Adaptive Server to write the new configuration information to the quorum device.
Enabling sybcluster and Sybase Control Center After a Manual Configuration
To use sybcluster or Sybase Control Center to manage the cluster after a manual configuration, start Sybase Control Center remote command and control agent on each node in the cluster, and then deploy the connection agent to each node.
