Today doubt has arisen with a coworker if it remains necessary to run the script Changeperm.sh in version 11g. This script gives permissions for third-party providers or other to files as listener.ora, tnsnames.ora, etc.
When looking at the script engine software, we see that is not shown, in our case the version is 126.96.36.199. Consulting MOS (formerly Metalink) can see the specifics in note 834626.1, please read for more information, but this script is no longer necessary.
