Network Adapter error while connecting Jira 4.2 to Oracle 11G database

Anandhi A

Got this error while trying to install Jira 4.2 and connect it to Oracle 11g database.

OS : Redhat Linux 5.5
Jira : Jira Version 4.2 Enterprise Standalone
Database : Oracle 11G R2
Java : JDK 6u37

Attempting to connect to the Oracle database server...
Could not connect to the DB: The Network Adapter could not establish the connection.

The driver oracle-jdbc-5.jar is also available.

I have oracle and Jira in the same system only. But i cant connect it. Please tell me how to solve this.

Its quite clear now that the when you are running the program or script, linux is not able find it under /usr/local/bin then /bin, /usr/bin and finally in /home/myname/bin.

To add these to your PATH variable , edit the .profile file add the values and at the end, after running the $echo PATH command , the o/p should look something like -

/usr/local/bin:/bin:/usr/bin:/home/myname/bin

Hi Anandhi,

The possible reasons could be -

using the wrong URL

wrong port number or IP address

listener is not configured properly

The listener process (service) is not running. You can re-start it with the "lsnrctl start" command

Hi Naren,

I gave correct data only.

I tried the lsnrctl command. But i get a command not found error.:(

Also, i get the same 'command not found' error for ls -l command.

Please help me how to solve this....

Thanks in advance

You need to check whether your environment variables are set properlyy-
$echo ORACLE_HOME (Path to oracle home)
$echo PATH (See that '$ORACLE_HOME/bin' is in $PATH variable)

If you can't see the oracle home directories on running above commands, then you haven't set the environment variables.\
Set the environment variable -

ORACLE_HOME

ORACLE_SID

TNS_ADMIN

Example
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export ORACLE_SID=orcl

And now you can run the command 'lsnrctl start' or 'lsnrctl status' command.

Please refer this guide -

Hope it works finely.

I have set all those variables. I could see the values when i give echo $ORACLE_HOME etc.

But no other command is working. Like 'ls', 'su' ,'rm', 'rmdir', 'lsnrctl' etc...:(

How should i solve this..
