Step 4. Define an ODBC Data Source

Step 4. Define an ODBC Data Source

Define an ODBC data source on the Search Server to connect to IBM DB2 UDB. The
Identity Resolution
 components access the database through ODBC. You must create ODBC data sources for each database that you plan to access.
  1. Open the
    odbc.ini
     file that you can find in the
    <Identity Resolution Installation Directory>\bin
     directory on Windows or
    <Identity Resolution Installation Directory>/bin
     on UNIX, and add or update the following database entries: 
    [<Service Name>]
DataSourceName = <ODBC DSN>
driver = <ODBC Driver>
server = <Native Database Service>
[connect_attributes = <Keyword1=Value1;Keyword2=Value2;...>]
[connect_string_udb = CONNECT TO <Database Name>]
[connect_attr_only = <Text1>]
    Configure the following parameters:
    Service Name
    Service name that
    Identity Resolution
     uses to refer to the database service.
    ODBC DSN
    Data Source Name. If you do not specify any value, it defaults to the service name.
    ODBC Driver
    Name of the ODBC driver. The driver name does not include the directory path. Enter one of the following values:
    • db2cli
       on Windows
    • db2
       on UNIX
    • libdb2.a(shr_64.o)
       on 64-bit AIX environments
    Native Database Service
    Name of the database alias.
    Keywords
    List of connection string keywords that
    Identity Resolution
     uses to generate a connection string that establishes a connection with IBM DB2 UDB.
    The format uses the following values:
    • Keywords
      . Optional. Connection string keywords that your ODBC driver supports. If you enable the
      connect_attr_only
       parameter, the specified values override the database source definitions and creates the connection string based only on the specified values. If you do not include the
      connect_attr_only
       parameter,
      Identity Resolution
       uses the specified values and the database source definitions to create the connection string.
    • Database Name
      . Optional. The database name which authenticates the connection to IBM DB2 UDB.
    • Text1
      . Optional. Indicates whether to use only the connection string keywords or the connection string keywords along with other data source definitions to create the connection string. Enter any text, such as
      Yes
      , to use only the keywords specified in the
      connection_attributes
       parameter to create the connection string. If you want to use the specified keywords with other database source definitions, do not add the
      connect_attr_only
       parameter to the
      odbc.ini
       file.
    The following sample configuration indicates to use only the specified connection string keywords to create the connection string: 
    [KRBTEST]
driver = /opt/ibm/db2/V11.1/lib64/libdb2o.so
server = KRBTEST
connect_attributes = DSN=DBKRB;
connect_string_udb = CONNECT TO DBKRB;
connect_attr_only = Yes
    For the preceding sample configuration, you get the following connection string which enables connection to IBM DB2 UDB using Kerberos authentication:
    DSN=DBKRB
    You need not specify User ID or Password in the
    connect_attributes
     parameter as
    Identity Resolution
     uses the predefined Kerberos authorization.
    A sample configuration file,
    odbc.ini.ori
    , is located in the following directory:
    • On Windows:
      <Identity Resolution Installation Directory>\bin
    • On UNIX:
      <Identity Resolution Installation Directory>/bin
    If you use multiple databases, add the database entries for each database. For example: 
    [srcDBcli] 
driver = db2cli 
server = (local) 
DataSourceName = srcDBcli

[tgtDBcli] 
driver = db2cli 
server = (local) 
DataSourceName = tgtDBcli
  2. Open the ODBC Data Source Administrator by performing the following tasks:
    1. From the Windows Control Panel, click
      Administrative Tools
      .
    2. In the
      Administrative Tools
       dialog box, double-click
      Data Sources (ODBC)
      .
  3. On the
    User DNS
     tab or
    Service DNS
     tab, click
    Add
    .
  4. Select
    IBM DB2 ODBC DRIVER
    , and click
    Finish
    .
  5. Follow the instructions in the Wizard, and ensure that you enter the following values:
    • Specify a data source name. Ensure that the data source name matches the data source name that you specify in the
      odbc.ini
       file.
    • Specify a default database.
