11G Oracle Install problems

Question

Ok, not sure what is going...
I installed Oracle 11g on Linux. Everything was working, I could access the database via Enterprise Manager, then I re-boot and EM no longer works, I figured this has something to do with some script to make it auto start at boot, so I searched the internet and found a script and made sure that it matched my paths and version numbers.
as a oracle user when I type
oracle@dragonfly:~$ echo $ORACLE_HOME
/u01/app/oracle/product/11.1.0/db_1
but
oracle@dragonfly:~$ echo $ORACLE_SID
I get a blank, would like to learn where to do the setting for oracle SID, is it in /etc/profile ? my SID is orcl
in /etc/oratab I put a Y for this db instance.
Anyways, when I try to manually start EM, I get these problems:
root@dragonfly:/u01/app/oracle/product/11.1.0/db_1/bin# ./emctl status dbconsole
Environment variable ORACLE_SID not defined. Please define it.
ok, let me define it:
root@dragonfly:/u01/app/oracle/product/11.1.0/db_1/bin# export ORACLE_SID=orcl
root@dragonfly:/u01/app/oracle/product/11.1.0/db_1/bin# ./emctl status dbconsole

Oracle Enterprise Manager 11g is not running.
Logs are generated in directory /u01/app/oracle/product/11.1.0/db_1/dragonfly.kodiaktechnical.net_orcl/sysman/log
then I type it again:
./emctl start dbconsole
and I see this...
