J2EE and CRM Web Channel Administration on access restricted Systems using tunneling through secure shell (SSH).
in our environment we sometimes get access to remote Unix-based systems using the putty tool , but actual port based network access is restricted, so you cannot access all these nice
gadgets, like SDM, Visual-Admin, Log-Viewer and sometimes even the “native” http port of your remote engine (you only can access some parts of the server via http through a reverse proxy for example).
a possible solution
get a user account to your remote system via secure shell[sometimes you’ll get one 😉 , download putty, create a session in then tool, and then configure port-tunneling.
this is done in the settings dialog of th putty tool:
Now You connect to your system using these port mappings, and can
access your App-Servers HTTP, Telnet and P4 Ports as if a local engine is running.
You could use:
- Visual Administrator,
- Software Delivery Manager,
- Logviewer, and
- your browser.
to do e.g. XCM configuration simply point your browser to the admin page of your shop application.
to restart you application you could use the telnet console:
- start a command shell locally
- telnet 127.0.0.1 50708 (above sample, port depends on instance of WAS J.),
- logon to telnet console,
- jump to relevant cluster node using: jump 0 (node number)
- add deployment commands using: add deploy
- stop your application using: stop_app sap.com/crm.b2b (your applications name).
- start your application using: start_app sap.com/crm.b2b (your application name)
- if you are unsure about what the name of your application is, you could use list_appin order to display all the deployed apps.
for getting an overview of the available commands you can type ‘man’.
