Junior DBA’s struggle sometimes and scratch their head without knowing the cause of simple errors.
Instead of trying to search for the error on internet,it is better to look at the error and identify the cause.
I try to execute runInstaller from a directory path to install the grid software where the software files actually exists but the name of directory has spaces when i copied from windows using winscp like this
[root@exadb2 ~]# cd /cell/GRIDDATABASE\ 11G\ 64\ BIT/
The installation file should be unzipped completely before copying the files to linux.So runInstaller consider the space as multiple folders and couldnot find the absolute path from the root folder.
Another point to keep in mind is appropriate permissions on the folders with ownership.Followed by the oracle inventory file.
Once i renamed the directory with single name,runInstaller was able to identify the oui from the absolute path.
