TMA-ORACLE-REMOTE-OS-AUTHENT

Ensure 'REMOTE_OS_AUTHENT' is set to FALSE

KritisLevel 1Otomatisoracle-db

Deskripsi

TRUE trusts the client's operating-system user name for OPS$ accounts, which any remote host can spoof. If the parameter no longer exists in the release it is treated as FALSE. Run on the database host as the Oracle software owner with ORACLE_HOME, ORACLE_SID and PATH set; connects with 'sqlplus -S / as sysdba' (OS authentication).
