------------otras cosas------------------
que el usuario de instalacion este en el grupo dba
dar privilegios 777 a oracle pero no al bin/oracle, que debe tener otros permisos, ahorita los busco.

###Meterse a /etc/environment como sudo y agregarle unas lineas
sudo gedit /etc/environment

ORACLE_HOME="/u01/app/oracle/product/11.2.0/xe"
ORACLE_SID="XE"
NLS_LANG="/u01/app/oracle/product/11.2.0/xe/bin/nls_lang.sh"
ORACLE_BASE="/u01/app/oracle"
ORACLE_TERM="xterm"
TNS_ADMIN="/u01/app/oracle/product/11.2.0/xe/network/admin"

y por aquello tambien crear sta que ocupa el append

sudo nano /etc/profile.d/envars.sh
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
