Step 3. Define an ODBC Data Source

You must define an ODBC data source on the Search Server to connect to Oracle. The

Identity Resolution

components access the database through ODBC except the

Identity Resolution

Table Loader, which directly loads data into the database. You must create ODBC data sources for each database that you plan to access.

To define an ODBC data source, open the

odbc.ini

file that you can find in the

<Identity Resolution Installation Directory>\bin

directory, and add or update the following database entries:

[<Service Name>]
driver = <ODBC Driver>
server = <Native Database Service>
ServerName = <Oracle Database Instance>
[connect_attributes = <Keyword1=Value1;Keyword2=Value2;…>]
[connect_attr_only = <Text1>]

Configure the following parameters:

Service Name: Service name that
Identity Resolution
uses to refer to the database service.
ODBC Driver: Name of the ODBC driver that communicates with the database. The driver name does not include the directory path.; Use one of the following values:
On Windows.
sqora32.dll

On UNIX.
libsqora.so
Native Database Service: Name of the database service that you configure in the database.
Oracle Database Instance: Name of the database instance. The
Identity Resolution
installer uses the same value as that of the database service.
Keywords: List of connection string keywords that
Identity Resolution
uses to generate a connection string that establishes a connection with the database server.; 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.

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:
[o12clx6] ServerName = o12clx6.cbr driver = sqora32.dll server = o12clx6.cbr connect_attributes = UID=James;DSN=Orcl;PWD=secret; connect_attr_only = yes

You can use the following environment variables instead of configuring the connection string keywords in the
odbc.ini
file:
SSA_USE_SQLDRIVERCONNECT_ATTRIBUTES

SSA_USE_SQLDRIVERCONNECT_ATTRIBUTES_ONLY

For more information about these environment variables, see the
Informatica
Identity Resolution
Operations Guide
.

You can find a sample configuration file,

odbc.ini.ori

, 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:

[oraclesrc] 
driver = ssaoci9.dll 
server = oraclesrc 

[oracletgt] 
driver = ssaoci9.dll 
server = oracletgt
