Connecting to a database from Windows systems

To enable an integration node to connect to a database, define the ODBC data source name (DSN) for the database.

Before you begin

Check that you have set up your environment so that the integration node can connect to the database. Most database managers set up the required environment when you install, but others supply a database profile that you must run. For information about environments and running database profiles, see Running database setup scripts.

About this task

Configure an ODBC data source by using the ODBC Data Source Administrator:
  1. Click Start > Control Panel > Administrative Tools > Data Sources (ODBC).
  2. Click the System DSN tab and click Add.
  3. Complete the steps in the following sections for the databases that you are working with.

    If you need more information about a particular database product, see the product-specific documentation.

IBM® DB2® UDB
Define a data source for IBM Db2 UDB:
  1. Select the driver IBM DB2 ODBC DRIVER.
  2. Enter the data source name (DSN) and description.
  3. Select the correct database alias from the list.
  4. Click Finish to save your definition.
  5. Click OK to close the ODBC Data Source Administrator.
  6. If you need to use Global Coordination with your database from IBM Integration Bus on Windows systems, the next task is to set up the 32-bit environment that is needed by WebSphere® MQ, see Setting your environment to support access to databases.
You must register the data source as a system data source.
If you prefer, you can use the Configuration Assistant instead of the ODBC Data Source Administrator:
  1. Open the IBM Db2 Configuration Assistant.
  2. Right-click the database and select Change Database.
  3. Select Data Source.
  4. Select Register this database for ODBC. Select the system data source option.
  5. Click Finish.
  6. The Test Connection dialog opens automatically and you can test the various connections.

Then, complete these additional steps:
  1. Reopen the ODBC Oracle Driver Setup dialog box, see Step 1 for Oracle above.
  2. On the Security tab:
    1. In the Authentication section, set the Authentication Method to Encrypt Password.
    2. In the Encryption Section, set the Encryption Method to SSL Auto.

Oracle using Advanced Security (OAS)

Complete the steps for Oracle above.

Then, complete these additional steps:

  1. Reopen the ODBC Oracle Driver Setup dialog box, see Step 1 for Oracle above.
  2. On the Advanced Security tab:
    1. Select the Encryption Level that you want to use. Choose from the following options:
      • 0 - Rejected. If rejected, or no match is found between the driver and server encryption types, data that is sent between the driver and the database server is not encrypted or decrypted. If the Oracle server has its sqlnet.encryption_server setting set to "REQUIRED" and this option is selected, then the connection to the Oracle database fails.
      • 1 - Accepted. Encryption is used on data that is sent between the driver and the database server if the database server requests or requires it.
      • 2 - Requested. Data that is sent between the driver and the database server is encrypted and decrypted if the database server permits it.
      • 3 - Required. Data that is sent between the driver and the database server must be encrypted and decrypted. If the Oracle server has its sqlnet.encryption_server setting set to "REJECTED" and this option is selected, then the connection to the Oracle database fails.
    2. Select the Encryption Types that you want to use.
    3. Select the Data Integrity Level you want to use. Choose from the following options:
      • 0 - Rejected. A data integrity check on data that is sent between the driver and the database server is refused. If the Oracle server has its sqlnet.crypto_checksum setting set to "REQUIRED" and this option is selected, then the connection to the Oracle database fails.
      • 1 - Accepted. A data integrity check can be made on data that is sent between the driver and the database server. Data integrity is used if the database server requests or requires it.
      • 2 - Requested. The driver enables a data integrity check on data that is sent between the driver and the database server if the database server permits it.
      • 3 - Required. A data integrity check must be performed on data that is sent between the driver and the database server. If the Oracle server has its sqlnet.crypto_checksum setting set to "REJECTED" and this option is selected, then the connection to the Oracle database fails.
    4. Select the Data Integrity Types that you want to use.
  3. Click OK to close the ODBC Data Source Administrator.
