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

UBUNTU is NOT a supported OS & therefore you have NO guarantee that Oracle will ever work on this system

>Moreover my service is working
please post COPY & PASTE proof that above is true.

what clues exist near the tail end of the alert_SID.log file for this instance?

what is ORACLE_SID for this instance?

Contrary to any previous claims, it does not appear that you have any actual database; least with the SID of ORCL

find / -name alert_\*.log -ls 2>/dev/null

Moreover when I created the database using dbca it keep popping up the alter 'ORA-12547: TNS:lost contact' but show successful creation in end.
few moments ago I try to reconfigure the database with dbca (as its only way i have to view it) when I give user/pwd on dbca interface to reconfigure database it showed 'Retreveing Information' popup but again 'ORA-12547: TNS:lost contact' alert arrive and 'Retreveing Information' popup disappear.
so dbca also only show this db but cant connect it.

Ok if there is no database, then please tell me how can I create a database in my situation? as 'ORA-12547: TNS:lost contact' not let dbca create a database.
How can I overcome 'ORA-12547: TNS:lost contact' so that I can create new database using dbca.

You're back to the first reply you got - maybe you won't make it work, ever, on Ubuntu.

Well, DBCA seems to not work correctly.

You could try creating a database manually.

Let's make it even simpler. Use vi to create a file:
vi $HOME/initorcl.ora

insert just one line into this file,
db_name=orcl

Then launch SQL*Plus, like this:
sqlplus / as sysdba

and issue this command:
startup nomount

I tihnk you will get your error at that point. If you don't, create your database:
create database;

thanks every one who tried to help me out.
I got it done finally , there was no possible solution I have for my error 'ORA-12547: TNS:lost contact' in my case.
So I dorp the os user 'oracle' and start a fresh/clean installation.

What different I did this time is that, I followed a different documentation this time.
I followed this doc as primary
http://sumitkumarojha.blogspot.com/2013/01/install-oracle-11g-r2-on-ubuntu-1204-64.html

and this doc as secondary
http://www.makina-corpus.org/blog/howto-install-oracle-11g-ubuntu-linux-1204-precise-pangolin-64bits

and the old doc that I used as only doc at previous installation as last doc
http://www.gizmojunkee.com/2012/05/installing-oracle-11gr2-on-ubuntu-12-04/

with combination of above 3, I got a clean installation (but 'database creation' failed at installation time)
but as there was no 'ORA-12547: TNS:lost contact' this time so i have created new database with dbca and its up and working now.

One more thing i change is that inventory directory was pointing to path '/mnt/u01/.....' and i can't change it so finally i find that inventory path is hardcode in file '/etc/oraInst.loc'
i modified the path in above path to more appropriate path.

thanks John Watson
thanks ThomasG
thanks Littlefoot
special thanks BlackSwan

OK then, it is, after all, possible to install Oracle on Ubuntu. Thank you for sharing documents you found useful when solving the problem! I hope you'll be able to use Oracle as well (because, that's the whole point, I suppose).
