Shell Programming and Scripting

Dear Experts,

I am new to the shell scripting.
I am looking for a shell script to connect to one Unix/Linux server1 to other Unix/Linux server2 and trigger a SAP Event in that server2 (Which will trigger a job in SAP).
Is this possible to connect from one server to the other server securely using Shell Scripting?
Is it possible to trigger that shell script from an operating system command?
I think, its possible, but I want confirmation from experts before I proceed the solution approach.
Please suggest on the possibility and how much time it may take to write that script?

Thanks & Regards,

(1) Yes of course it is possible.

(2) The time it takes to right such a script depends on your skill level.

Thank you Neo.

You probably want to setup public key/private key authentication
between the servers, then you won't need a password to connect.

Thank you.
We have SFTP connection between Server1 and Server2.
Can I use that in my script for authentication and write the code to connect and to the server2 and execute some command in server2?

I sounded like you wanted to write a shell script that ran on one server, but was called from another server. IMHO, sftp if only for transferring files from one server to another. But ssh can be called with the -C where you can specify a command. You can put that command in double quotes to make sure that everything gets sent. As in:

Code:

ssh user@server2 -C "df -h ${MOUNT_POINT}"

So you basically just need to write your script to trigger the SAP event. There might be code fragments on the internet with something similar to what you need.

Hi,

So you basically just need to write your script to trigger the SAP event.--> Thats correct. The script will be in server1 and the SAP Event trigger will be in server2.

My requirement at high level is:
1. Connect from SAP PI (Server 1) OS to SAP ECC (server 2) OS securely in script. both are in same network.
2. Trigger a SAP Event in SAP ECC (Server 2) once connected to it with the help of same script (Running on server 1).
3. Close the connection.
The script run will be called from SAP PI Communication channel with the help Run OS Command after message process.
