CANNOT START ORACLE 10G IN OPENSUSE 11.1

Hallo!I managed to install successfully the Oracle 10g on OpenSUSE 11.1.

I have tried to configure the machine so that the Oracle listener and database start up when the computer boots by trying to open the /etc/oratab and trying to change the ‘N’ at the end to a ‘Y’.

Unfortunately,the /etc/oratab does not exist in my system.But I have been able to open YaST and Go to /etc/sysconfig Editor > Productivity > Databases > Tools > Oracle > DB and change the following to “yes”:

  • START_ORACLE_DB
  • START_ORACLE_DB_LISTENER
  • START_ORACLE_DB_EMANAGER
  • START_ORACLE_DB_ISQLPLUS

Unluckily,when I type the following commands at the terminal,I get the response that they (the commands) do not exist

a. Start Oracle listener – lsnrctl start
b. Start Enterprise manager services – emctl start dbconsole
c. Start iSQL *Plus – isqlplusctl start
d. Check if sqlplus is working:
sqlplus “connect / as sysdba“

How do I solve this problem?
