How mapping information is stored

The mapping information is stored in the Windows or Windows NT Registry.

The Dynamo mappings are stored in:

HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\PowerDynamo\
Mappings

Encrypted Sybase Central connection profile information is stored in:
```
HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\Sybase Central\Profiles
```
This registry folder contains a set of folders. Each folder has the name of a profile, and contains the name of the associated ODBC data source, as well as the user ID and password used to access the data source.
The ODBC data source, which you may have created using the ODBC Administrator, is held in:
```
HKEY_CURRENT_USER\SOFTWARE\ODBC\ODBC.INI
```
If you are running your Web server as a Windows NT service, it does not use a login ID, and consequently has no access to the CURRENT_USER registry. In this case, you must create your ODBC data source as a System DataSource Name (System DSN). System DSN descriptions are held in the LOCAL_MACHINE registry.
The ODBC driver used to access the data source is part of the data source definition. The available ODBC drivers are listed in:
```
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI
```
