This problem can be due to a couple different situations. If you want OUI to use the JRE installed in /usr/java, then you should modify the oraparm.ini file which can be found in Disk1/install location of where you unzipped the software. Modify this file and attempt the installation again.
Another possibility is that the permissions on the mount point for the Unix filesystem are different from the permissions on the filesystem that contains the Oracle software. This assumes that you have staged the software on a Unix filesystem. If this is the case, follow these instructions to change the permissions:
- Unmount the filesystem.
- Change the permissions on the mount point using the "chmod" command.
- Mount the filesystem.
- Try starting the OUI again.
