SQL> select * from v$version where rownum=1;Use the RMAN command to start RMAN from the operating system command line.
RMAN connections to a database are specified and authenticated in the same way as SQL*Plus connections to a database. The only difference is that RMAN connections to a target or auxiliary database require the SYSDBA privilege. The AS SYSDBA keywords are implied and cannot be explicitly specified. See Oracle Database Administrator‘s Guide to learn about database connection options when using SQL*Plus.r‘s Guide to learn how to start RMAN from the command line
You must issue the RMAN command and any options at the operating system command line rather than at the RMAN prompt.
The command name that you enter at the operating system prompt is operating system-dependent. For example, enter rman in lowercase on Linux and UNIX systems.
If you start RMAN without specifying either CATALOG or NOCATALOG on the operating system command line, then the RMAN session is effectively inNOCATALOG mode unless you execute a CONNECT CATALOG command (see Example 3-32). If you maintain a recovery catalog, then the best practice is to connect RMAN to the recovery catalog before performing RMAN operations.
