This section demonstrates how to synchronize a relational database table to Oracle Internet Directory. It contains these topics:
In this example, the following relational database table containing employee data is synchronized with Oracle Internet Directory.
Table 9-1 Employee Table

You can find a sample profile for this example in the directory $ORACLE_HOME/ldap/odi/samples. Also present there are the sample configuration and mapping files. In this example:
The name of the table is Employee
The Profile Name is TESTDBIMPORT.
The employee number (EMPNO) is used to JOIN a database record with a directory entry. It is specified in the OID Matching Filter (orclOdipOIDMatchingFilter) attribute described in the attributes reference chapter of the Oracle Identity Management User Reference.
This table is present in the testsync/testsyncpwd schema in a database. The database is located on the host machine.acme.com, the database listener port is 1526 and the SID is iasdb. The database URL is machine.acme.com:1526:iasdb.
Appropriate read/write permissions have been given explicitly to this profile, namely, orclodipagentname=testdbimport, cn=subscriber profile, cn=changelog subscriber, cn=oracle internet directory
The profile is created in configuration set 1.
This example uses the same Additional Configuration Information file described earlier in "Preparing the Additional Configuration Information File".
The mapping file for this example contains the following:
DomainRules NONLDAP:dc=testdbsync,dc=com:uid=%,dc=testdbsync,dc=com AttributeRules ename: : : :cn: :person ename : : : :sn: :person uid : : : :uid: :inetOrgperson: EMail: : : :mail: :inetOrgperson Telephone: : : :telephonenumber: :inetOrgperson empnum: : : :employeenumber: :inetOrgperson
This mapping file specifies the following:
Directory entries are created as uid=%,dc=testdbsync,dc=com. The % is a placeholder for the actual value of uid. The uid must be present in the mapping rules so that it has a value after the mapping. Otherwise the DN construction fails.
Both the cn and sn attributes are to have the same value as ename.
The uid element must have the value of the EMail prefix, which is the element of the e-mail address prior to the '@' character.
empnum becomes employeenumber in the directory entry.
telephone becomes telephone number in the directory entry.
The directory integration profile for this example contains the attribute values as described in Table 9-2. A sample integration profile with these values populated and the corresponding mapping and configuration files are available in $ORACLE_HOME/ldap/odi/samples directory. You can create the profile by running the Directory Integration and Provisioning Assistant in the createprofile mode and specifying the file as the argument. Alternatively, you can create the profile by using the Oracle Directory Integration and Provisioning Server Administration tool.

Use the Directory Integration and Provisioning Assistant to upload the additional configuration information file, as follows:
$ORACLE_HOME/bin/dipassistant modifyprofile [-h hostName] [-p port] [-D bindDn] [-w password] -profile profName odip.profile.mapfile=absolute path name of configuration file
Use the Directory Integration and Provisioning Assistant to upload the mapping file, as follows:
$ORACLE_HOME/bin/dipassistant modifyprofile [-h hostName] [-p port] [-D bindDn] [-w password] -profile profName odip.profile.mapfile=absolute path name of mapping file
In this example, the sequence of steps in the synchronization process is:
The Oracle directory integration and provisioning server starts a new profile thread for the TESTDBIMPORT profile every time the value specified in the scheduling interval (orclOdipSchedulingInterval) attribute expires.
The profile thread reads the additional configuration information to get the SQL to execute, and then runs the SQL.
For every row retrieved from the database, the mapping rules are applied to the record and LDAP attributes are created.
Depending on the OID Matching Filter (orclOdipOIDMatchingFilter) attribute, the directory integration and provisioning server determines whether a matching entry exists in Oracle Internet Directory or not. If it exists, then it is updated. If not, then a new entry is created. After the directory operation, the last applied change number (orclodipConDirLastAppliedChgNum) attribute is updated.
When a row is retrieved from the database, it is in the following form:
EmpNum: 98357 EName: JOHN DOE UID: JOHN.DOE EMAIL: JOHN.DOE@ACME.COM TELEPHONE: 435-324-3455 Modified_Date: 20000102000000
After the mapping is performed on this record, the output is in the following form:
dn: uid=john.doe,dc=testdbsync,dc=com uid: JOHN.DOE cn: JOHN DOE sn: JOHN DOE mail: JOHN.DOE@ACME.COM employeenumber: 98357 telephonenumber: 435-324-3455 objectclass: person objectclass: inetorgperson
A subtree search is made in the directory with the filter employeenumber=98357 under the domain dc=testdbsync,dc=com. If the search yields an existing entry, then that entry is updated. Otherwise, a new entry is created. Because the OID Matching Filter (orclOdipOIDMatchingFilter) attribute is set to employeenumber, every database record retrieved must have that column. In this case, it is EmpNum as it maps to employeenumber.
Any other attributes in the mapping file that are not in the data retrieved by the SQL are ignored—for example, the attribute birthday.
After the profile thread processes all the change records from the SQL, it updates the directory with correct values for these attributes:
Last Applied Change Number (orclodipConDirLastAppliedChgNum)
Last Execution Time (orclOdipLastExecutionTime)
Last Successful Execution Time (orclOdipLastSuccessfulExecutionTime)
