RMAN的"rman: can't open target"错误在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
<ASCII|roff|TkMan|Tk|Sections|HTML|XML|MIME|LaTeX|LaTeX2e|RTF|pod>]
[-S(ource of man page passed in)] [-F(ormatted man page passed in)] [-r
<man reference printf string>] [-l <title printf string>]
[-V(olume) <colon-separated list>] [-U(RLs as hyperlinks)] [-b
(show subsections)] [-k(eep head/foot)] [-n(ame of man page)
<string>] [-s(ection) <string>] [-p(aragraph mode toggle)]
[-t(abstops spacing) <number>] [-N(ormalize spacing, changebars)]
[-y (zap hyphens toggle)] [-K (declare that page has no breaks)]
[-d(iff) <file> (diff of old page source to incorporate)]
[-M(essage) <text> (included verbatim at end of Name section)]
[-R(ebus words for TkMan)] [-C (enable Tcl/Tk formatting)] [-o (no op)]
[-O <arg> (no op with arg)] [-q(uiet--don't report warnings)]
[-h(elp)] [-v(ersion)]
[<filename>]
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 ~/product/10.2.0/db/bin/rman
-The End- |
