Subject RE: Unable to connect to oracle database from sqoop
Date Fri, 21 Jun 2013 07:08:44 GMT
Hello Michal,
Thanks for your reply. I tried with your input but after that also i'm getting the same error.
i've given below the script i used. ./sqoop-list-databases --connect  "jdbc:oracle:thin:username/password@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyIPAddress)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=cp)))"
Do i need to add any jar file in the sqoop lib apart from ojdbc jar? 
when i try the above script i got the below exception. I've added the complete stack trace.

Hello Manickam,
the Oracle connection parameters are a bit confusing sometimes (not a Sqoop problem). The
thin client, which you are using, does not support full Oracle*Net client and it does not
work with tnasnames.ora. So you either specify the service directly (in your case, the listener
running on localhost must provide service "cp"). Or you can provide the full connection string
(taken from tnsnames.ora) in the commandline:

For example, like this:sqoop import --connect  "jdbc:oracle:thin:username/password@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=YOURSERVICENAME)))"
...


Hope this helps,Michal

Hi,
Given below is the scoop script i used. 
 ./sqoop list-databases --connect jdbc:oracle:thin:@localhost:1521/cp --username scott --password
tiger
JDBC driver directory - which directory you mean here? i have put ojdbc jar in sqoop lib folder.
Is that fine or am i missing anything here? 

Thanks,
Manickam P

Hi,

Please send your Sqoop script, and the output of "ls" command on your JDBC driver directory.


Thanks

Hi,

I am trying to import details from oracle through sqoop but i got the below error. 

   13/06/20 09:09:21 ERROR manager.OracleManager: Failed to list databasesjava.sql.SQLException:
Listener refused the connection with the following error:

ORA-12514, TNS:listener does not currently know of service requested in connect descriptor


I've put an entry into the TNSname.ora file and also added ojdbc jar with sqoop lib folder.

Please help me to resolve the issue.


Thanks,
Manickam P
