ORACLE_HOME_LISTNER is not SET dbstart error Oracle Enterprise Linux

Question

ORACLE_HOME_LISTNER is not SET dbstart error Oracle Enterprise Linux
Hallo!I am a newbie in Oracle 10g having installed Oracle 10g in Oracle Enterprise Linux version 4 update 7.
I am trying to automate the startup of the Listener,Database,Enterprise Manager and isqlplus during boot.
I have tried running the dbstart script but an error resulted.After research,I found out that I am supposed to edit line 78 of the dbstart script from
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
To
ORACLE_HOME_LISTNER=$ORACLE_HOME
Even after this,when I run the dbstart script,I receive the error below.
[root@joey-oel ~]# cd /u01/app/oracle/product/10.2.0/db/bin/
[root@joey-oel bin]# ./dbstart
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Processing Database instance "orcl": log file /u01/app/oracle/product/10.2.0/db/startup.log
When I view the log file startup.log,the information is as below

I am trying to run the dbstart as the oracle user.When I try doing this as below
[oracle@joey-oel ~]$ $ORACLE_HOME/bin/dbstart $ORACLE_HOME
chmod: changing permissions of `/u01/app/oracle/product/10.2.0/db/startup.log': Operation not permitted
Processing Database instance "orcl": log file /u01/app/oracle/product/10.2.0/db/startup.log
Even when I try changing the permissions of startup.log as below,
chmod 777 startup.log
the error still appears.
