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:

Provides only local access to local databases. This instance includes the Name Server, DBMS Server, and its own set of tools.

Runs on one or more nodes in a cluster environment, which provides access to local databases from any of the nodes running Ingres.

This installation includes the Name Server, DBMS Server, and its own set of Ingres tools. It does not require a Communications Server.

Local databases, transaction log files, and other Ingres areas must be located on commonly accessible cluster devices.

If an Ingres node in the cluster installation crashes, any incomplete transactions on the failed node are recovered by Ingres processes.

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)

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)

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.
