Understanding SequeLink^® Services

In this section, we take a closer look at SequeLink services and how they work. Remember that SequeLink services are components of SequeLink Server.

SequeLink data access services can handle data access requests from any SequeLink Client. A data access service "services" a specific type of data store (for example, Oracle or DB2). SequeLink provides an optimized data access service for each type of data store it supports. Multiple SequeLink data access services can run on the same server. When you complete the installation of the SequeLink Server software as documented in the SequeLink Installation Guide, a SequeLink data access service is configured for the type of SequeLink Server you installed (for example, SequeLink Server for Oracle or SequeLink Server for DB2).

When a SequeLink Client connects to a SequeLink data access service, the data access functionality of the session is governed by the attributes defined for the data access service. For example, if the service attribute DataSourceReadOnly=Select, the client application can perform only Select statements when using that service. Refer to "SequeLink® Service Attributes" in the SequeLink Administrator's Guide for a complete list of service attributes.

SequeLink Agent services carry out configuration, management, and monitoring requests from any SequeLink Manager. When you complete the installation of the SequeLink Server software as documented in the SequeLink Installation Guide, the SequeLink Agent functionality that is integrated into the Data Access Service is created, configured, and is ready for requests.
