Sybase recommends that you plan your Adaptive Server shared-disk cluster before you begin the configuration process.
Before you begin, determine:
The location of the $SYBASE installation directory.
The cluster name.
The number of instances and the instance names.
The Domain Name Service for the network on which the cluster will run. The Unified Agent and the sybcluster utility will not function properly if the DNS entries are not entered correctly for each node.
The number of nodes in the cluster and the node names. Sybase recommends that you use one node for each of the instances in the cluster with two or more engines per instance.
The raw devices to be used by each database device. For the Cluster Edition, you must create all devices, database devices, and quorum devices as raw devices on shared disks.
Local user temporary databases do not require shared
storage and can use local file systems created as private devices.
The range of port numbers used by each instance to exchange messages with other instances via the private interconnection. Choose unique port numbers that are not in use by other applications.
The Adaptive Server plug-in and sybcluster supply
default values if your system does not have an existing standard.
The query or listening port number for each instance. Choose unique port numbers that are not in use by other applications.
The IP addresses of the private primary and secondary network cards on each node. Only UDP network protocol is supported at this time.
