Accessing Databases using SQLClnt on an Intermediate Node

SQLClnt usually runs on the same node as the IVR application. You can also run

SQLClnt on an intermediate node. Using an intermediate node centralizes the

database client software while using SQLClnt to accelerate access to the database.

The configuration is highly scalable. You can install a number of nodes, each of them

running multiple instances of an application coupled with a group of nodes in which

multiple instances of SQLClnt are running. When SQLClnt runs on the intermediate

node, you must also install the database client on the intermediate node.

Use one of the following configurations when installing SQLClnt and related

processes.

• Typical installation with SQLClnt and related processes installed on the same

node as the application.

• SQLClnt on an intermediate node but related processes are on the same node.

• SQLClnt and vmst on an intermediate node.

• SQLClnt and periq on an intermediate node.

The IVR application uses the libvagsqlclnt.so library.

The IVR application uses the vagsqlclnt.dll library.

SQLClnt on the Same Node as the IVR Application

The following diagram shows a typical configuration where SQLClnt and the

application are installed on the same node.
