Cause

This error may be caused due to one the following reasons:
a) Oracle client provider is not installed on the sql server, you are trying to connect.

b) SSMA Extension Pack is not installed on SQL Server

c) Oracle Client may not be accessible to the DataMigrator utility from Extension Pack. This utility is started with the same account used to run SQL Agent.

Resolution

SSMA Data Migrator needs Oracle client provider installed on the SQL Server machine to perform data migration. When it does not find Oracle Client provider it gives this error.

1. Install the Oracle Client provider on your sql server and verify data migration.

2. Cross check Extension pack is installed on your sql server machine

3. Oracle Client may not be accessible to the BCPDataMigrator utility from Extension Pack. This utility is started with the same account used to run SQL Agent. Make sure this account has access to the Oracle client folder and it’s contents.
