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.

To configure connectivity to the Data Integration Service, PowerCenter Integration Service, or PowerCenter Repository Service process, log in to the machine as a user who can start the server process.

Set the SYBASE and PATH environment variables.

SYBASE
. Set the variable to the Sybase Open Client installation directory. For example if the client is installed in the /usr/sybase directory:

Using a Bourne shell:

$ SYBASE=/usr/sybase; export SYBASE

Using a C shell:

$ setenv SYBASE /usr/sybase

PATH
. To run the Sybase command line programs, set the variable to include the Sybase OCS bin directory.

Using a Bourne shell:

$ PATH=${PATH}:/usr/sybase/OCS-15_0/bin; export PATH

Using a C shell:

$ setenv PATH ${PATH}:/usr/sybase/OCS-15_0/bin

Set the shared library environment variable.

The Sybase Open Client software contains a number of shared library components that the Data Integration Service, PowerCenter Integration Service, and PowerCenter Repository Service processes load dynamically. Set the shared library environment variable so that the services can find the shared libraries at run time.

The shared library path must also include the installation directory of the Informatica services

(server_dir)

Set the shared library environment variable based on the operating system.

The following table describes the shared library variables for each operating system.

Operating System	Variable
Linux	LD_LIBRARY_PATH
AIX	LIBPATH

For example, use the following syntax for Linux:

Using a Bourne shell:

$ LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$HOME/server_dir:$SYBASE/OCS-15_0/lib;$SYBASE/OCS-15_0/lib3p;$SYBASE/OCS-15_0/lib3p64; export LD_LIBRARY_PATH

Using a C shell:

$ setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:$HOME/server_dir:$SYBASE/OCS-15_0/lib;$SYBASE/OCS-15_0/lib3p;$SYBASE/OCS-15_0/lib3p64;

For AIX

Using a Bourne shell:

$ LIBPATH=${LIBPATH}:$HOME/server_dir:$SYBASE/OCS-15_0/lib;$SYBASE/OCS-15_0/lib3p;$SYBASE/OCS-15_0/lib3p64; export LIBPATH

Using a C shell:

$ setenv LIBPATH ${LIBPATH}:$HOME/server_dir:$SYBASE/OCS-15_0/lib;$SYBASE/OCS-15_0/lib3p;$SYBASE/OCS-15_0/lib3p64;

Edit the .cshrc or .profile to include the complete set of shell commands. Save the file and either log out and log in again, or run the source command.

Using a Bourne shell:

$ source .profile

Using a C shell:

$ source .cshrc

Verify the Sybase ASE server name in the Sybase interfaces file stored in the $SYBASE directory.

Verify that you can connect to the Sybase ASE database.

To connect to the Sybase ASE 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.
