Check for errors in the installation logs, then verify that you can start the SAP Mobile Platform Server and log in to Management Cockpit.
<SMP_HOME> is the installation location you specified (the default is <$HOME>/SAP/MobilePlatform3/).
A quick way to do this is:
grep -i error SMP*log
Server start-up is complete when you see this message The SMP server has initialized and is ready.
When you run go.sh, stderr is redirected to the server_daemon.log file; stdout is not redirected. For troubleshooting, you can run go.sh -clean to clear the OSGi cache before starting the server.
Use the Upgrade: SAP Mobile Platform Server for Linux for the support package to upgrade your SAP Mobile Platform installation.
