oracle 19c 安装打补丁时，补丁是Version 19.20.0.0.0

Opatch升级到12.2.0.1.39完成，

执行opatch会报错

[oracle@dlidcprodatago 35320081]$ ../opatch prereq CheckConflictAgainstOHWithDetail -ph ./

../opatch: line 839: [: too many arguments

Java (1.7) could not be located. OPatch cannot proceed!

OPatch returns with error code = 1

解决方案：

cd /app/oracle/product/19.0.0/dbhome_1/OPatch

rm -rf jre

cp -r /app/oracle/product/19.0.0/dbhome_1/jdk/jre/ .

将Opatch 的jre删除，将oracle_home下的jdk/jre拷贝到Opatch目录下

在打补丁，可以正常打补丁了。

[oracle@dlidcprodatago 35320081]$ ../opatch prereq CheckConflictAgainstOHWithDetail -ph ./
