After you install Informatica Data Replication on an Oracle target system, you must perform several tasks to prepare the system for data replication.
Verify that the Oracle Client is installed. The Data Replication Applier and InitialSync components use the Oracle Client to access the Oracle target tables.
The Oracle Client version must be equal to or later than the Oracle target database version.

Verify that the ORACLE_HOME environment variable is defined and that the PATH environment variable includes the ORACLE_HOME\bin directory. Also, verify that an ORACLE_SID environment variable is defined for Oracle source instance.
Disable Automatic Diagnostic Repository (ADR) for Data Replication sessions with the Oracle target so that the Applier or InitialSync can generate a core file if a fatal error occurs.
To disable ADR, add the following parameters to the sqlnet.ora configuration file:
