DirectConnect is the ECDA component that provides basic connectivity to non-Sybase data sources. In particular, it provides access management, transaction management, and remote systems management through DirectConnect Manager.
DirectConnect data access servers provide connectivity between clients located throughout the enterprise and enterprise data servers. You can use a DirectConnect server on its own to connect directly to a single, non-Sybase data server. Or, you can combine DirectConnect servers with Adaptive Server or Replication Server, the Sybase products that provide a Transact-SQL™ interface so you can access, move, and replicate data in a heterogeneous environment.
DirectConnect consists of a server and one or more access service libraries, which have specific sets of configuration properties. The server provides the framework in which the service libraries operate. Each access service library accesses data from a particular target database, such as DB2 UDB, Informix, Microsoft SQL Server, and Oracle.
ECDA includes these DirectConnect servers:
DirectConnect for DB2 UDB, which provides connectivity to DB2 UDB running on z/OS, AS400, NT, and UNIX platforms
DirectConnect for Informix, which provides connectivity to Informix database servers
DirectConnect for Microsoft SQL Server, which provides connectivity to Microsoft SQL Server databases
DirectConnect for ODBC, which provides connectivity to ODBC-accessible database servers
DirectConnect for Oracle, which provides connectivity to Oracle database servers
DirectConnect Manager is a GUI systems management tool for administering DirectConnect. It runs on Windows and UNIX platforms, within the Sybase systems management framework, Sybase Central. DirectConnect Manager displays a consolidated view of all DirectConnect servers across your enterprise.
Using DirectConnect Manager, you can:
Manage DirectConnect servers on multiple platforms.
Change configuration properties of DirectConnect servers, service libraries, and services.
Create and copy services by copying an existing service and giving it a unique name.
Create new servers.
Start and stop existing servers.
Start, stop, and delete services. (From a remote site, DirectConnect Manager is the only way you can start a service.)
Test the availability of a data source by creating a connection to it.
Retrieve a DirectConnect server log file or a subset of the log, and view log file messages with a text editor.
Update DirectConnect server connection information.
View the status of a service and data source on the desktop.
The DirectConnect ODBC driver lets your ODBC client application work with DirectConnect.
