Java (1.7) could not be located
问题现象
opatch version
./opatch: line 839: [: too many arguments
./opatch: line 839: [: too many arguments
Java (1.7) could not be located. OPatch cannot proceed!
OPatch returns with error code = 1
解决方法
是将Opatch 的jre删除，将oracle_home下的jdk/jre拷贝到Opatch目录下
rm -rf Opatch/jre
cp -r $ORACLE_HOME/jdk/jre Opatch/
接下来就可以正常打补丁了
