Connect to Sybase from a Connection Pool in WebLogic

The CData JDBC Driver for Sybase enables you to follow standard procedures to integrate Sybase data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Sybase in WebLogic Server.

Deploy the JDBC Driver in WebLogic Server

To deploy the driver, add the driver JAR to your classpath. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, prepend the path to the JAR to the WEBLOGIC_CLASSPATH environment variable in WL_HOME\common\bin\commEnv.cmd/sh. This script is located in WL_HOME\common\bin\. For example:

In WebLogic 12.2.1 if you want to add the driver to a specific domain, you can simply place the driver JAR and .lic file into DOMAIN_HOME\lib; for example, ORACLE_HOME\user_projects\domains\MY_DOMAIN\lib. These files will be added to the server classpath at startup.

Earlier versions require that you manually add the driver to the classpath: Prepend the following to the PRE_CLASSPATH environment variable in setDomainEnv.cmd/sh. This script is located in the bin subfolder of the folder for that domain.

After making these changes, restart the server.

Create a JDBC Data Source for Sybase

After deploying the driver, log into the WebLogic Administration Console and create the connection.

1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
2. On the JDBC Data Source Properties page, enter the following information:
   • Name: Enter a user-friendly name; for example, sybasejdbc.
   • JNDI Name: Enter the path the JDBC data source will be bound to; for example, jdbc/Sybase.

   • Database Type: Select Other.

3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

   • Driver Class Name: Enter the driver class, cdata.jdbc.sybase.SybaseDriver.

   • URL: Enter the JDBC URL. A typical JDBC URL is below:

     jdbc:sybase:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;Charset=iso_1;

     To connect to Sybase, specify the following connection properties:

     • Server: Set this to the name or network address of the Sybase database instance.
     • Database: Set this to the name of the Sybase database running on the specified Server.

     Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

     Sybase supports several methods for authentication including Password and Kerberos.

     Connect Using Password Authentication

     Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

     • User: Set this to the username of the authenticating Sybase user.
     • Password: Set this to the username of the authenticating Sybase user.

     Connect using LDAP Authentication

     To connect with LDAP authentication, you will need to configure Sybase server-side to use the LDAP authentication mechanism.

     After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

     Connect Using Kerberos Authentication

     To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos.

   See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

   You can find an example connection string below: Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Sybase JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.sybase.jar

   Fill in the connection properties and copy the connection string to the clipboard.

4. Database User Name: Enter the username, if not specified in the JDBC URL.
5. Password: Enter the password, if not specified in the JDBC URL.

After selecting the server where you want to deploy the JDBC data source, you can now connect to Sybase data.
