Server Set

Use these pages to view information about the servers in a server set and the service level agreements associated with the server set.

Prerequisite: For the Connection Manager, the OpenAdmin Tool (OAT) for Informix® requires IBM® Informix 11.70.xC3 and the Connection Manager that is packaged with Informix 11.70.xC3 or later, or with IBM Informix Client Software Development Kit (Client SDK) 3.70.xC3 or later.

A server set is a collection of database servers whose client connection requests are managed by a Connection Manager. It is one type of connection unit that is managed by a Connection Manager.

Server List

Use this page to view information about servers in the connection unit.

Server Group: The name of the database server group.
Server Group Members: The servers that are members of the database server group.

SLA

Use this page to view information about the service level agreements (SLAs).

SLA

The name of the SLA. An SLA is the contract between specified client applications and their service providers, in this case, the Informix database servers. Based on service level agreements, the Connection Manager connects the client applications to the appropriate servers.

Servers

The servers in the SLA listed in order of connection preference with the first server listed having the highest connection priority. For example, the list g_one,g_two,g_three indicates that the client is connected first to server g_one. If server g_one is not available, the client is connected to server g_two. If server g_two is not available, the client is connected to server g_three. When a group of servers is in parenthesis, all the servers have the same connection priority. For example, the following list gives each server equal priority: (g_one,g_two,g_three).

Service Port

The port number associated with the SLA.

Mode

The mode that the Connection Manager uses to redirect client requests.

Redirect: The Connection Manager redirects client connection requests to the appropriate server. The Connection Manager returns the appropriate server node, IP address, and port number to the client application (depending on the SLA definition). The client application connects to the server using the IP address and port number that the Connection Manager provides.
Proxy: The Connection Manager functions as a proxy server when clients connect to database servers from outside a firewall. The Connection Manager actively routes all client communications to and from the database servers.
