    The RMAN database registration process encountered an error, specifically ORA-01403 (no data found), during its initial synchronization due to an existing restore point. Despite entering commands correctly, the registration failed because RMAN could not process the restore point metadata across the CDB. Upon identifying this issue through trace analysis, the restore point was deleted, allowing successful completion of the database registration process, highlighting the importance of internal procedures in troubleshooting.

    This post explains how a Data Pump export in an Oracle RAC environment failed with misleading errors, including ORA-48128, related to symbolic links and file access. The actual cause was an NFS-mounted Data Pump directory that was accessible from only one RAC node. Adding CLUSTER=N resolved the issue by keeping all Data Pump workers on the local instance. Alternatively, mounting the NFS filesystem on all RAC nodes also resolves the problem.
