Unable to get environment variable values while executing script on remote server

Question

I m working on hp Unix box. I m trying to execute remote script through ssh. My target script uses environment variables value internally. When i do manually ssh and do echo $(env_vairable_name), it prints the value. But when i execute script remotely, it does not get env variable value. I m trying blow command to execute remote script. ssh remote_user@remote_hostname "~/my_script_on_remote.ksh". Please advice.

Thanks.

This is how i m assigning value: db_user=$ASMM_INSTALL_DB_USER db_pwd=$ASMM_INSTALL_DB_PASSWORD db_instance=$ASMM_INSTALL_DB_INSTANCE And here i m using them set -A res `sqlplus -s $db_user/$db_pwd@$db_instance <<ENDOFSQL — Dheeraj kumar

You should set the environment variables in the startup file for the Korn shell on the remote host.

You can also use the file ~/.ssh/environment, but ssh(1) warns (emphasis added):

Additionally, ssh reads ~/.ssh/environment, and adds lines of the format “VARNAME=value” to the environment if the file exists and users are allowed to change their environment. For more information, see the PermitUserEnvironment option in sshd_config(5).

Finally, you can change the script to take command-line arguments instead of read its parameters from the environment.

Error code: 1 On remote script i m using set -A res `sqlplus -s $db_user/$db_pwd@$db_instance <<ENDOFSQL command to connect. Any idea why i m getting this error. Thanks.

Looks like an error message from the SQL Plus command itself; and a cryptic one, too. I've no idea what that command even is, so I can't help you out.
