When you install and create your cluster, you choose whether to configure the cluster in shared or private installation mode:
Shared installation – supports a shared file system created using a Network File System (NFS) or a cluster file system. A cluster created using a shared installation supports a single $SYBASE installation directory, Adaptive Server home directory, and server configuration file.
Private installation – requires a separate $SYBASE installation directory, Adaptive Server home directory, and server configuration file for each instance. Parity among server configuration files is maintained by the master configuration file on the quorum device.
Sybase recommends that you use LDAP as your directory
service when using a private installation.
If the installation mode is private, the cluster input file automatically contains this entry:
installation mode = private
If the installation mode is shared, the cluster input file automatically contains this entry:
installation mode = shared
See the installation guide for your platform for instructions about installing and configuring the cluster in private or shared installation mode.
