         During installation , A path will be entered for instance installation , This path is generally not allowed to be changed , After pressing it, of course . But there are exceptions , What if I change it ？

        First, check whether it is in the shutdown state , Shutdown refers to whether the instance is shut down kill perhaps onmode, The shared memory area requested by the communication will not be released if the machine is not shut down , Restart will conflict .

        Then the first and easiest way that I haven't tried is to change things back , In theory, it is not a problem

        The second method is to change the paths under all instance paths to the latest ,grep -rl Look up the file containing the path , then sed Change . If you still can't get up, change the primary group of the file , Next, change permissions ,4770 6770 What? , Refer to other examples .

       

         DBSA Permission error reports are own Your settings have changed ,root：root This kind of , then mod Join in s jurisdiction , Basically no problem .

        in addition , Move core files 、 Move the whole instance , Need to shut down , Otherwise there would be security Protect , Your example is quacking , I won't change . Will change the path and DBSA problem .
