Hi
I have installed Oracle 11gR2 on Ubuntu 12.04 on amazon VM using following doc.
http://www.gizmojunkee.com/2012/05/installing-oracle-11gr2-on-ubuntu-12-04/
all components installed successfully but 'Database Configuration Assistant' failed so database also didn't installed successfully.
I have created new database using dbca. database created successfully but keep giving the warning 'ORA: 12547: TNS: lost contact' many times within database installation.
After that i try to connect database but failed.
when i give complete string "sqlplus user/pwd@service"
it give following error
ORA-12541: TNS:no listener
when i connect as "sqlplus /nolog"
it connect to sql prompt
then on sql prompt i do "SQL> conn /as sysdba"
it give following error
ORA-12547: TNS:lost contact
Moreover my service is working but listener is not responding at all.
if i pass any of following command the os didn't return any error or warning or anything and os prompt jump to next line.
lsnrctl
lsnrctl status listener_name
lsnrctl start listener_name
lsnrctl stop listener_name
what i have already done by reading the different forums is as under, but it didn't worked.
cd $ORACLE_HOME/bin
chmod 6751 oracle
above didn't worked for me.
$ORACLE_HOME/root.sh from root
above didn't worked for me.
cd $ORACLE_HOME/bin relink
above didn't worked for me.
can some one help me out of (ORA-12547: TNS:lost contact | ORA-12541: TNS:no listener)?
I wonder the installation doc i use may missed any package need install on os.
Thanks
