Major Configuration Options
Initially, you can configure your installation as one of the following major types. Later, you can install other products or modify parameter settings to add more capabilities to your installation. For example, you can add networking capabilities to a stand‑alone installation that is connected to a network. Or you can add client capabilities to an installation that you initially configured as a networked DBMS Server.
The major configuration options are as follows:
Stand-alone DBMS Server
Provides only local access to local databases. This instance includes the Name Server, DBMS Server, and its own set of tools.
Required products: DBMS Server, tools
Networked DBMS Server
Allows remote clients to access its databases through a network. (If tools are installed, local users also can access its databases.)
This instance includes the Name Server, DBMS Server, Communications Server, Data Access Server, ODBC driver, and JDBC driver.
By installing Ingres tools and then modifying the Ingres Net connection data, you can add outgoing client capabilities to a networked DBMS Server instance. Doing so enables it to act both as a client of a remote DBMS Server and as a DBMS Server to its own remote clients.
Required products: DBMS Server, Ingres Net, ODBC driver, JDBC driver, Ingres tools (optional, but required for local access to local databases)
Networked DBMS Server with Ingres Star
Allows access to multiple databases--local and remote, Ingres and non-Ingres--simultaneously. This instance includes Ingres Star, Name Server, DBMS Server, Communications Server, Data Access Server, ODBC driver, and JDBC driver. It may also contain Ingres tools.
Required products: DBMS Server, Ingres Net, ODBC driver, JDBC driver, Ingres Star, Ingres tools (optional)
Client
Has its own set of Ingres tools and accesses databases on a networked DBMS Server instance on a remote node. This installation includes the Name Server, Communications Server, Data Access Server, ODBC driver, JDBC driver, and Ingres tools. It does not contain the DBMS Server.
You can configure a networked DBMS Server instance as a client of another DBMS Server on a remote node. To do so, install Ingres tools on the DBMS Server, and then add client capabilities by modifying the Ingres Net connection data.
You can set up a client in a different environment to access an Ingres database in your current environment. For example, a client in a Windows environment can access a database in a Linux environment. For more information, see the Connectivity Guide.
Required products: Ingres Net, ODBC driver, JDBC driver, Ingres tools
Network File System (NFS) Client
Uses a Network File System to share all Ingres files on a networked DBMS Server instance. This instance contains no Ingres files on its own node.
Required products: A networked DBMS Server instance on a node in the Network File System. The ingmknfs utility must be run to create the NFS client instances and configure the DBMS Server for NFS-client use.
