Getting started with Devart ODBC Driver for SAP Sybase ASE

Quick start: Connect to SAP Sybase ASE with ODBC

To connect to SAP Sybase ASE using the Devart ODBC Driver:

1. Download and install the Driver for Windows, macOS, or Linux.
2. Activate the Driver using your activation key, or continue with the 30-day trial. On Windows and macOS this is a step in the installer; on Linux, run the activator afterwards.
3. Create an ODBC data source (DSN) and select Devart ODBC Driver for ASE.
4. Configure the connection by specifying the ASE server, port, database, user ID, and password.
5. Use the DSN in your ODBC-compatible application to connect to ASE and work with its data.

The following sections provide detailed installation and configuration instructions for each supported operating system.

Prerequisites

Before you begin, make sure your environment meets the following requirements:

• Database server: SAP Adaptive Server Enterprise 16.0 or later, or Sybase Adaptive Server Enterprise 12.5.4 or later.
• Operating system: 32-bit or 64-bit Windows (including Windows Terminal Server), macOS x64 or ARM (Apple silicon), or 32-bit or 64-bit Linux.
• Network access: Make sure the client computer can connect to the ASE server host and port. The default port is 5000.
• Connection details: ASE user credentials and the database name.
• DSN configuration tool (optional): On macOS and Linux, you can use Devart ODBC Administrator to create and manage data sources through a graphical interface. The tool is distributed separately from the Driver and is available on the Devart website. Alternatively, configure data sources manually in the odbc.ini file.
• Activation key: A purchased version of the Driver requires an activation key. For evaluation purposes, you can use the trial version, which is valid for 30 days from installation.
• Administrator rights: Required to install the Driver on all supported operating systems.

Then verify that the DSN created during installation is registered:

odbcinst -q -s

The output should include the automatically created DSN.

Configure an ODBC data source

In this guide, you create a Data Source Name (DSN) for the ODBC connection and verify the connection details. A DSN stores connection settings, such as the server, port, database, and optionally credentials, that applications use to connect to ASE. Applications can also connect without a DSN, by passing the same parameters in a connection string.

Configure a DSN on Windows

1. In Windows Search, enter ODBC Data Sources, and open the ODBC Data Source Administrator that matches the bitness of your application.

2. Select the User DSN, System DSN, or File DSN tab, and click Add:

• User DSN — Available only to the user who creates it.
• System DSN — Available to all users on the computer.
• File DSN — Stores connection settings in a file that can be shared between computers where the required ODBC driver is installed.

3. In the Create New Data Source dialog, select Devart ODBC Driver for ASE, and click Finish.

4. In the Devart ODBC Driver for Adaptive Server Enterprise Configuration dialog, enter a Data Source Name and an optional Description.

5. On the General tab, specify the connection parameters:

• Server — the host name or IP address of the ASE server.
• Port — the port the ASE server listens on. The default value is 5000.
• Database — the database to connect to.
• User ID and Password — your ASE credentials. Select Save Password to store the password in the DSN.

6. Optional: Click Test Connection to verify the connection settings.

7. Click OK to save the DSN settings.

To secure the connection with SSL or an SSH tunnel, or to fine-tune metadata, timeout, and compatibility behavior, use the Security Settings and Advanced Settings tabs of the same dialog. For details, see Secure connections and Advanced connection options.

Configure a DSN on macOS

DSNs are managed in Devart ODBC Administrator, a graphical tool that is distributed separately from the Driver. Download and install it from the Devart website before you continue.

1. Open Devart ODBC Administrator (root). Select the System DSN tab (recommended), and click Add. Enter your administrator password when prompted.

2. In the Choose a driver dialog, select Devart ODBC Driver for ASE and click OK.

3. In the Devart ODBC Driver for ASE Configuration dialog, enter a Data Source Name, an optional Description, and the connection parameters. To store the password in the DSN, select Save Password.

4. Optional: Click Test Connection to verify the connection settings.

5. Click OK to save the DSN settings.

To configure a DSN by editing the odbc.ini file, see Connect on macOS in the documentation.

Configure a DSN on Linux

As on macOS, Devart ODBC Administrator is distributed separately from the Driver. Download and install it from the Devart website before you continue.

cd ~/Downloads
sudo apt-get install -y ./devartodbcadministrator_amd64.deb

1. Open Devart ODBC Administrator (root), select the System DSN tab, and click Add.

2. In the Choose a driver dialog, select Devart ODBC Driver for ASE and click OK.

3. In the Devart ODBC Driver for ASE Configuration dialog, enter a Data Source Name, an optional Description, and the connection parameters. To store the password in the DSN, select Save Password.

4. Optional: Click Test Connection to verify the connection settings.

5. Click OK to save the DSN settings.

Alternatively, define the DSN in /etc/odbc.ini. The installation creates a sample DSN named DEVART_ASE that you can adjust:

[DEVART_ASE]
Driver=Devart ODBC Driver for ASE
Data Source=your_ase_server_name
Port=5000
Database=your_ase_database_name
User ID=your_ase_user_id
Password=your_ase_password

To verify the data source from a terminal, connect to it with isql, the command-line tool provided by unixODBC. Replace <your_dsn_name> with the name of your DSN:

isql -v <your_dsn_name>

Connect to ASE using a connection string

In addition to using a DSN, you can connect to SAP ASE by specifying the connection parameters directly in an ODBC connection string. This type of connection is known as a DSN-less connection.

The following table summarizes when to use each connection method:

For a DSN-less connection, use the following connection string as a starting point:

DRIVER={Devart ODBC Driver for ASE};Server=your_ase_server;Database=your_database_name;Port=5000;User ID=your_username;Password=your_password

Replace the placeholder values with your connection details:

• Server — the host name or IP address of the ASE server.
• Database — the name of the database to connect to.
• Port — the port the ASE server listens on. The default value is 5000.
• User ID — your ASE username.
• Password — your ASE password.

For example:

DRIVER={Devart ODBC Driver for ASE};Server=ase.example.com;Database=SalesDB;Port=5000;User ID=ase_user;Password=your_password

You can also specify advanced connection parameters to configure connection timeout, IP version, ODBC behavior, and other Driver settings.

For the complete list of supported options, see ASE ODBC connection string parameters.

For examples of using a connection string in different programming languages, see Connect to ASE from programming languages.

Troubleshoot common issues

If you cannot connect to SAP Sybase ASE through the Devart ODBC Driver, use the following solutions to resolve common connection issues.

"Product is not activated or has been deactivated" error

This error occurs when the Driver has not been activated or its activation is no longer valid. Activation is required for both purchased and trial versions.

• Windows: Open the DSN configuration dialog, go to the License tab, click Input Activation Key, and enter your activation key.
• macOS and Linux: In Devart ODBC Administrator, select the DSN and click Configure. On the License tab of the configuration dialog, click Input Activation Key and enter your activation key. Alternatively, run the aseodbcactivator utility from the Driver installation folder with your activation key.

After activation, test the connection again.

ODBC data source not found or Driver not available

If your application cannot find the DSN or the Devart ODBC Driver for ASE, check the application and Driver bitness.

A 32-bit application cannot use a DSN created in the 64-bit ODBC Data Source Administrator, and a 64-bit application cannot use a DSN created in the 32-bit administrator.

Make sure that:

• The DSN is created in the ODBC administrator that matches your application's bitness.
• The corresponding 32-bit or 64-bit version of the Driver is installed.
• The application is configured to use the correct DSN.

Cannot connect to the ASE server

If the Driver cannot reach the SAP ASE server, verify the server and network settings:

• Make sure the Server field contains the correct host name or IP address.
• Verify the Port value. SAP ASE uses port 5000 by default, but your server may be configured to use a different port.
• Make sure the ASE server is reachable from the client computer.
• Check that your firewall allows outbound connections to the ASE server and port.
• If the server is available only over IPv4 or IPv6, set IP Version accordingly on the Advanced Settings tab.

Login or database connection fails

If the ASE server is reachable but authentication or database access fails, check the connection credentials and database settings:

• Verify the User ID and Password.
• Make sure the database specified in the Database field exists.
• Confirm that the ASE login has permission to access the database.
• If Save Password is cleared, the application must provide the password at runtime. Applications that cannot display a password prompt may fail to connect.

ASE connection times out

If the server is available but the connection takes too long to establish, increase Connection Timeout on the Advanced Settings tab. The default connection timeout is 15 seconds.

Also check the network connection and make sure the ASE server is not overloaded or temporarily unavailable.

SSL connection fails

If Use SSL is enabled and the connection fails, verify the SSL configuration on the Security Settings tab.

Check the paths to the CA certificate, client certificate, and private key, and make sure the private key password is correct.

If the problem persists, enable ODBC tracing to capture the ODBC function calls, and contact Devart support with the log.
