Shell script verify connection to Oracle if not successful
i have a script that connects to the oracle database and executes the query statements. it works fine and i would like to add some message to check if the connection to oracle is not successful.

basically this is the code snippet:
Code:
#!/bin/sh
...
...
...
sqlplus -s username/password@dbName <<EOF > script.log
...
...
...
EOF
exit

how do I add it on the script?

thank you.

You need to create a script or wrapper that expects a return status from the server and process the return status.

More specifically, you can use:

Code:
WHENEVER SQLERROR EXIT SQL.SQLCODE
WHENEVER OSERROR EXIT

For example:

Code:
WHENEVER SQLERROR EXIT SQL.SQLCODE
begin
  SELECT COLUMN_DOES_NOT_EXIST FROM DUAL;
END;
/

And for OS errors:

Code:
WHENEVER OSERROR EXIT FAILURE
START no_such_file

Check out the reference material for more details:
