start off by seeing that you can 'see' everything as needed.

Code:
telnet 10.5.199.106 1521

Code:
tnsping PHYGD1

Beyond this, if the instance is down...or the schema and/or object is not present you'll want to speak to your DBA. Good luck!

1) echo $ORACLE_SID returns the following:

bash: PHYGD1: command not found

where PHYGD1 is the correct SID.

2) tnsping to VOMSD1 returns OK

3) telnet to the server says 'Connected'

From the basic checks everything looks fine to me.

Could someone please confirm if the tnsnames.ora entry in Unix can exactly be same as the one in windows?

because i am able to connect to the remote database through toad from my windows machine w/o any issues.

That's surely not possible!!

Is that what you really typed?

Code:
echo $ORACLE_SID

I'm surely not the only person who uses oraenv to set an Oracle environment?

(a) Run the commands posted earlier on the Unix/Linux dollar prompt.
(b) Select the relevant area from your terminal emulator program (PuTTY/Konsole/Gnome Terminal/XTerm etc.), copy it and paste it over here.
So that we could see what exactly you typed, and its result.

@durden_tyler - I am able to establish a DB connection now. Using the following command from Unix prompt:

Code:
sqlplus <User_ID>/<Password>@'(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.5.199.106)(PORT=1521))(CONNECT_DATA=(SID=PH YGD1)))'

I was now trying to use the sample code which you had provided below -

Code:
#!/bin/bash
#Connect to the database using sqlplus
x=`sqlplus -s /nolog <<EOF
connect test/test
set pages 0 
select x from t;
exit
EOF`

As follows:

Code:
sqlplus gidicm/gidicm@'(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.5.199.106)(PORT=1521))(CONNECT_DATA=(SID=PHYGD1)))' >> outputlogfile.log
echo "Step 1 Done"
select sysdate from dual;
ENDSQL
echo "Output_variable, sysdate=$sysdate"

This code is getting stuck at the select statement.

Could you please let me know the correct way to invoke a sql from shell script? Please note that the way I am using the command sqlplus needs to be the same as above...since i am able to establish connection using this command now.

Please advise.

Thanks!
Shruti

preface the line starting "echo ... " with the sqlplus command host. This is needed to produce a host-side command from within the sqlplus client...

But, you're also mixing and matching syntax provided by tyler and your original approach. As stated before, one step at a time...prove you can get the select to run from the command-line...manually, and then you can try to get it into a script.

I am sorry I did not explain it clearly before:

Yes, I was able to connect to the database from the Unix prompt and also I was able to run the following query successfully on the prompt. Please see the query ran and the output I got below:

Code:
bash-2.05b$ sqlplus gidicm/gidicm@'(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.5.199.106)(PORT=1521))(CONNECT_DATA=(SID=PHYGD1)))'

SQL*Plus: Release 9.2.0.8.0 - Production on Wed May 5 16:31:34 2010

SQL> select sysdate from dual;

SYSDATE
---------
05-MAY-10

SQL>

Now I am trying to include this simple query in my shell script. For which I have written the below script:

Code:
#!/bin/bash
sqlplus gidicm/gidicm@"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.5.199.106)(PORT=1521))(CONNECT_DATA=(SID=PHYGD1)))"<< EOF
'select sysdate from dual;
EOF'
echo "Output_variable, x=$sysdate"


This script is able to establish the database connection successfully...but it fails at the step where i try to fire the select query. I know i am missing the write syntax here....but that's where i need the help from you experts.

Thanks!
