在Linux上,安装完成之后,在测试RMAN时可能会遇到如下错误:
[Oracle@smsdbrac1 oracle]$ rman target /
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 ]
[-V(olume) ] [-U(RLs as hyperlinks)]
[-b (show subsections)] [-k(eep head/foot)]
[-n(ame of man page) ] [-s(ection) ]
[-p(aragraph mode toggle)] [-t(abstops spacing) ]
[-N(ormalize spacing, changebars)] [-y (zap hyphens toggle)]
[-K (declare that page has no breaks)]
[-d(iff) (diff of old page source to incorporate)]
[-M(essage) (included verbatim at end of Name section)]
[-R(ebus words for TkMan)] [-C (enable Tcl/Tk formatting)]
[-o (no op)] [-O (no op with arg)]
[-q(uiet--don't report warnings)] [-h(elp)] [-v(ersion)]

修正这个问题,我们只需要在Oracle用户的环境变量下,将$ORACLE_HOME/bin放在PATH变量前就可以了:
export PATH=$ORACLE_HOME/bin:${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
重新登录使环境变量生效,现在Oracle能找到正确的rman了:
[oracle@smsdbrac1 oracle]$ su - oracle
Password:
[oracle@smsdbrac1 oracle]$ which rman
