Rac trip in Huai'an

Huai'an so-and-so unit asked to install Windows2008 rac system, because it used to operate on linux, suddenly encountered such a project, the installation process is quite bumpy, at the beginning of installation, has been encountered various problems, the previous difficulties have been solved, and so encountered installation grid to 100%, jump out of the [INS-20802] grid infrastructure configuration failure, check the log, read a lot of information, all kinds of solutions have been tried It didn't work out for two hours, and there was really no good solution at that time. A decision was made early the next morning to delete the installed grid software and install the high version 11.2.0.4, so the installation was completed without resistance. Now when you think about it, it should be the oracle version of bug.
