Are you setting your ORACLE_HOME and ORACLE_SID environment?  Just because
you put it in /etc/oratab, it doesn't automatically set it for you

You must source /etc/oratab using the  oraenv command

$> . oraenv


oratab  is called by oraenv to determine ORACLE_HOME based on the ORACLE_SID
you enter.

You won't be able to access the instance if ORACLE_SID isn't set

Hi Mohammed,

Can you start the instance manually?
has user oracle enough rights on /etc/oratab?
how big is your SGA configured? Linux x86 doesn't support more than ~1,7 GB
without some bigger changes. These are not done with orarun!!

Yours, Ralf
