在Linux上，安装完成之后，在测试RMAN时可能会遇到如下错误：
rman: can't open target
?
这是由于调用的是非Oracle的RMAN的缘故：
[oracle@smsdbrac1 oracle]$ which rman
/usr/X11R6/bin/rman
?
在X11R6下存在一个名为rman的命令：
[oracle@smsdbrac1 bin]$ ./rman -help
rman
??? [-f ]
??? [-S(ource of man page passed in)] [-F(ormatted man page passed in)]
??? [-r ] [-l ]</span></span></span></p><br/><p class="a" style="MARGIN: 0cm 0cm 0pt; mso-char-indent-count: 1.11"><span lang="EN-US" style="FONT-SIZE: 9pt"><span style="COLOR: #103e7b"><span style="FONT-FAMILY: Arial"><span style="mso-spacerun: yes">??? </span>[-V(olume) <colon-separated list>] [-U(RLs as hyperlinks)]</span></span></span></p><br/><p class="a" style="MARGIN: 0cm 0cm 0pt; mso-char-indent-count: 1.11"><span lang="EN-US" style="FONT-SIZE: 9pt"><span style="COLOR: #103e7b"><span style="FONT-FAMILY: Arial"><span style="mso-spacerun: yes">??? </span>[-b (show subsections)] [-k(eep head/foot)]</span></span></span></p><br/><p class="a" style="MARGIN: 0cm 0cm 0pt; mso-char-indent-count: 1.11"><span lang="EN-US" style="FONT-SIZE: 9pt"><span style="COLOR: #103e7b"><span style="FONT-FAMILY: Arial"><span style="mso-spacerun: yes">??? </span>[-n(ame of man page) <string>] [-s(ection) <string>]</span></span></span></p><br/><p class="a" style="MARGIN: 0cm 0cm 0pt; mso-char-indent-count: 1.11"><span lang="EN-US" style="FONT-SIZE: 9pt"><span style="COLOR: #103e7b"><span style="FONT-FAMILY: Arial"><span style="mso-spacerun: yes">??? </span>[-p(aragraph mode toggle)] [-t(abstops spacing) <number>]</span></span></span></p><br/><p class="a" style="MARGIN: 0cm 0cm 0pt; mso-char-indent-count: 1.11"><span lang="EN-US" style="FONT-SIZE: 9pt"><span style="COLOR: #103e7b"><span style="FONT-FAMILY: Arial"><span style="mso-spacerun: yes">??? </span>[-N(ormalize spacing, changebars)] [-y (zap hyphens toggle)]</span></span></span></p><div class="article-middle-ad" style="margin: 30px 0; padding: 20px 0; text-align: center; clear: both;">
