Is -t or -T permission required in $ORACLE_HOME/log/ NodeName, drwxr-xr-t
11.2.0.4 latest patchset $ORACLE_HOME/log/exa3db01 with drwxr-xr-t
drwxr-xr-t 3 oracle oinstall 4096 Feb 9 2018 exa3db01
what is the purpose of the -t permission on this folder. also some have -T, which is considered unused. Should this be set ?
