> # SequeLink® Server System Administration

> SequeLink provides the following options for configuring and managing your SequeLink environment:

> - Local system administration allows you to configure and manage your SequeLink environment using the SequeLink Manager installed locally on a SequeLink Server.
> - Remote system administration allows you to configure and manage your SequeLink environment using the SequeLink Manager installed on the desktop of a networked client.

> NOTE: Only SequeLink 6.0 services can be configured, managed, or monitored with the SequeLink Manager 6.0.

> ### Local System Administration

> You can use the SequeLink Manager locally from the SequeLink Server to configure and manage your SequeLink environment; however, which SequeLink Manager tool you can use locally depends on your SequeLink Server platform.

> ### Remote System Administration

> Remote system administration allows you to configure and manage your data access environment from the convenience of your desktop regardless of your SequeLink Server platform. For example, suppose you are responsible for administering an environment with distributed data access involving a variety of data stores across your enterprise, such as Oracle on UNIX and Windows, and Microsoft SQL Server on Windows as shown in Figure 1-1. You can install the SequeLink Manager Snap-in on a Windows XP or Windows Vista networked client and perform administration tasks, such as configuring SequeLink service settings, from the convenience of your desktop.

> ### Using the SequeLink® Manager

> The SequeLink Manager tool can be used to perform administrative and monitoring requests.

> #### Administrative Requests

> The type of administrative requests you can issue to a SequeLink Agent and the SequeLink Manager tool you can use to issue the requests depends on the platform you are administering. The following list describes the types of administrative requests you can issue:

> - Configuration
> - Creating and managing SequeLink services
> - Creating and managing SequeLink server data sources
> - Configuring monitoring profiles, which determine the data access events that can be monitored (viewed) using the SequeLink Manager
> - Configuring event-tracing profiles, which determine the data access events that are written to an event trace file
> - Management
> - Starting and stopping SequeLink services
> - Stopping active data access user sessions
> - Reviewing traced events to analyze a problem during an earlier data access activity

> #### Monitoring Requests

> The SequeLink Manager allows you to perform the following monitoring tasks:

> - Viewing details about active services
> - Viewing active user sessions and information about live data access activities

> For example, you can easily view the number of transactions that have been processed or the number of rows that have been fetched by all user sessions. Also, if a user session is not performing correctly (such as the session repeatedly fetches thousands of rows), you can use the SequeLink Manager to identify and end that specific user session.

> Additionally, the SequeLink Manager allows you to troubleshoot previous events. For example, if an error occurs during a nightly data processing job, you can view an event trace to troubleshoot the problem.

> #### SequeLink® Manager Implementations

> SequeLink provides the following implementations of the SequeLink Manager:

> - SequeLink Manager Snap-in is a GUI designed as a snap-in to the Microsoft Management Console (MMC). It can be used to configure and manage SequeLink services, and to monitor data access activity.
> - SequeLink Manager Command-Line Tool is a command-line interface that can be used to configure and manage SequeLink services. Similarly, it can be used to monitor data access activity.
> - SequeLink Manager for z/OS is an ISPF dialog tool that can be used to create data access services on the z/OS platform, as well as configure and manage SequeLink services and monitor data access activity on z/OS. It can be installed only on z/OS platforms.

> Table 1-1 shows the platforms on which you can install and run the different implementations of the SequeLink Manager.
