DSEDIT
DSEDIT, Data Source Editor, is a Windows utility that creates and modifies
Omnidex data source objects. Data source objects are used along with Omnidex
Network Services to connect to an Omnidex Environment Catalog on the server
(local or remote), in client/server ODBC, JDBC and Client OmniAccess API
(CLOA) applications.
Using information contained in the data source, DSEDIT can also be used
to test network connections, show structural information about the database
and index installation, and perform simple retrievals against the database.
Data Source Objects
Data source objects are a collection of configuration information that
defines server and connection protocol information necessary to allow
a client application to talk to a remote server. This includes the host
(server) name or IP address, OdxNet listener port number, physical file
location of the Omnidex Environment Catalog, and other pertinent information.
This information is used by the Omnidex ODBC and JDBC drivers, as well
as the Omnidex Client OmniAccess API.
Some server only applications can connect directly to the Omnidex Environment
Catalog and will therefore not pass through an Omnidex Network Server
nor require a Data Source object. However, the Omnidex ODBC and JDBC drivers
are both client components of the Omnidex software, and therefore will
always pass through an Omnidex Network Server, regardless of the network
configuration. This means that single tier applications using ODBC or
JDBC, where the application and database reside on the same machine, will
go through an Omnidex Data Source object and an Omnidex Network Server.
UNIX and Linux Clients
A data source object is also required in client / server applications
when the client platform is not Windows. Although, DSEDIT is a Windows
only utility, meaning it will only run on the Windows operating system,
it can still be used to create data sources for use on the other supported
platforms.
Simply use the wizard to create a Generic or CLOA data source, passing
the appropriate server information, and save the data source to the local
machine. Since the data source is an ASCII text file, it can be easily
copied to another platform.
If your client application will be using ODBC to access the data, you
will need to make one minor edit inside the data source file. To do this,
open the data source file with any text editor and look for the ODBCDSNFILE=datasourcefilespec
near the top. It should be around the third line.
This tag shows the physical file location of the data source as it was
originally created on the Windows machine. You simply need to change the
path to show where you moved the data source file to. Save your changes
and exit.
That is all there is to it. The data source file is now ready for use
on the new client machine.
