1888636 - DOES_INSTALLATION_EXIST: Main Class Missing - Error in SWPM/MaxDB


In a SAP installation with MaxDB database, Software Provisioning Manager tool (SWPM) fails with following error:

ERROR      <timestamp>
Error during execution of command identifier 'DOES_INSTALLATION_EXIST' : Exception in thread "main" java.lang.NoClassDefFoundError: com/sap/sdb/core/main/cmd/SdbCmdMain

                at java.lang.ClassLoader.loadClass(
Could not find the main class:  Program will exit.

There is a similar error message 'DOES_INSTALLATION_EXIST' explained in SAP Note #2207314, but the installation scenario is different and so is the solution.
