错误:rman: can't open target

在Linux系统中,有时候会发现无法启动rman

如:

rman target / nocatalog

会报错

rman: can't open target

这纯属一个误会

原因是因为在linux中,有一个其他工具正好也叫 rman

运行一下:

[rollingpig@dbperf oracle] which rman

/usr/X11R6/bin/rman

[rollingpig@dbperf oracle] /usr/X11R6/bin/rman target / /usr/X11R6/bin/rman: can't open target

[rollingpig@dbperf oracle] echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/orabin/product/9.2.0/bin

所以,我们需要把ORACLE_HOME/bin的path放在:/usr/X11R6/bin 之前就可以了

[rollingpig@dbperf oracle] export PATH=$ORACLE_HOME/bin:$PATH

[rollingpig@dbperf oracle] rman target / nocatalog

好了,现在可以正常使用rman 了。
