On the Korn shell (<code>ksh</code>) — the default login shell on AIX 7.x, Solaris 11, HP-UX 11i, and many older Oracle 11g/12c reference builds — that operation is gated behind one line in <code>.profile</code>: <code>set -o vi</code>. Without it, the up-arrow key prints a literal escape sequence and the only way to repeat a long <code>RMAN BACKUP DATABASE PLUS ARCHIVELOG ...</code> invocation is to type it again.</p>
