Before you install Adaptive Server, start the HACMP services on the same node on which you are installing Adaptive Server. The HACMP node must be running on its service IP address, not the start or standby IP address.
Install the primary and the secondary servers. You can install the companions on either local or shared file systems.
If they are installed on shared file systems, the file systems cannot be the same for each companion. This is to prevent the file systems from overwriting each other during a device fail over. For example, you can install the primary companion on node1_sybase, but install the secondary companion on /node2_sybase.
If the servers are installed on local file systems, the name of the file systems must be the same. For example, both the primary and the secondary companion can be installed in /sybase.
The file systems that contain $SYBASE must be either local or shared; you cannot mix local and shared file systems for $SYBASE in the cluster.
The database devices for the primary companion must be devices in the shared volume group on the primary node (for example, shared_vg1), so the volume group for this node must be “varied on,” which means make the volume group active and accessible on this node.
If you are creating an asymmetric configuration, you can use any device (shared or local) for the database device of the secondary companion. If you are creating a symmetric configuration, you must use a device in the shared volume group on the secondary node (for example, shared_vg2) for its database devices, so the volume group for this node must be “varied on,” which means make the volume group active and accessible on this node.
The primary companion can be either a newly installed Adaptive Server, or it can be upgraded from an earlier version of Adaptive Server with existing databases, users, and so on.
The secondary companion must be a newly installed Adaptive Server without any user logins or user databases. This ensures that all user logins and database names are unique within the cluster. After configuration for failover is complete, you can add user logins and databases to the secondary companion.
See the installation documentation for your platform for information about installing and configuring Adaptive Server.
