GSS Features
This section provides information for new GSS features for Release 9.0
Multiple Instance GSS
Release 9.0 enables support for multiple data streams from one server or a single cluster setup to utilize multiple
instances of GSS with a single installation and multiple databases.
instances of GSS with a single installation and multiple databases.
In a cluster setup, there is only one installation per node. During installation, GSS is installed at a fixed location
(/opt/gss_global directory). The initial GSS installation does not create any GSS instance. Once GSS is installed on both
the nodes, the /opt/gss_global/make_gss_instance script utility creates instances as an when needed and validates the
conflicting ports/username across the instances.

the nodes, the /opt/gss_global/make_gss_instance script utility creates instances as an when needed and validates the
conflicting ports/username across the instances.
For all instances on the node, only one set of binaries and scripts are used. Each instance will have its own configuration
file, log directory, tools directory and separate PostgreSQL database. The alarms and events generated by each instance
are sent to its corresponding chassis. Individual GSS instance can also be stopped, started or switched over. Upgrade is
smooth and will involve minimum down time as possible.

Each GSS instance can be uninstalled separately and will not have any impact on the other instances. Global installation
can be only uninstalled if there are no instances configured or running on the system.
can be only uninstalled if there are no instances configured or running on the system.
The advantages of this feature include:
Only one installation required for multiple instances
One binary used across all the instances on the node
Upgrading one set of binaries would upgrade all the instances
In cluster mode resource groups, instances can be balanced across the nodes
