注意：downloading/uncompressing/unzipping opatch zip 文件时禁用防病毒软件，以便防病毒软件在downloading or uncompressing or unzipping opatch zip 文件时不会重命名/删除 opatch 文件。
5)
可以使用绝对路径来启动 OPatch：
如:
$ORACLE_HOME/OPatch/opatch version
或者可以把 OPatch 所在的目录加到 PATH 这个环境变量中,之后就可以在任何目录运行 OPatch 命令(opatch <args>)而不需要指定绝对路径
如:
For Korn / Bourne shell: % export PATH=$PATH:$ORACLE_HOME/OPatch For C Shell: % setenv PATH $PATH:$ORACLE_HOME/OPatch
