Connecting to a Sybase ASE Database from Windows
For native connectivity, install the version of Open Client appropriate for your database version. To ensure compatibility between Informatica and databases, use the appropriate database client libraries.
Install an Open Client version that is compatible with the Sybase ASE database server. You must also install the same version of Open Client on the machines hosting the Sybase ASE database and Informatica. To verify compatibility, contact Sybase.
If you want to create, restore, or upgrade a Sybase ASE repository, set allow nulls by default to TRUE at the database level. Setting this option changes the default null type of the column to null in compliance with the SQL standard.
Configuring Native Connectivity
You can configure native connectivity to a Sybase ASE database to increase performance.
The following steps provide a guideline for configuring native connectivity. For specific instructions, see the database documentation.
1. Verify that the SYBASE environment variable refers to the Sybase ASE directory.
For example:
SYBASE=C:\SYBASE
2. Verify that the PATH environment variable includes the Sybase OCS directory.
For example:
PATH=C:\SYBASE\OCS-15_0\BIN;C:\SYBASE\OCS-15_0\DLL
3. Configure Sybase Open Client to connect to the database that you want to access.
Use SQLEDIT to configure the Sybase client, or copy an existing SQL.INI file (located in the %SYBASE%\INI directory) and make any necessary changes.
Select NLWNSCK as the Net-Library driver and include the Sybase ASE server name.
Enter the host name and port number for the Sybase ASE server. If you do not know the host name and port number, check with the system administrator.
4. Verify that you can connect to the Sybase ASE database.
To connect to the database, launch ISQL and enter the connectivity information. If you fail to connect to the database, verify that you correctly entered all of the connectivity information.
User names and database names are case sensitive.
