Sure, I have add the account configured in the oracle agent to the media server's modified list, and the error occured when Remote Agent connect to oracle database, as the following error message said:
OCIServerAttach() failed with database credentials.
OCI_ERROR: ORA-12546: TNS: permission denied
Failed to logon to database, other error: Error code (0x3102)
Returning E_RMAN_LOGON_OTHER error (0xe000fe29)
It's strange that the oracle database credential (system) I set was not use to connect to the database, as the following message said:
RMAN_AttachToDLE: called
RMAN_AttachToDLE: User name ()
