2936962 - SUM on Linux : phase "MOD_SELROADMAP/SUMCHK_EXTBUILD" : Environment variable 'dbms_type' does not exist

You are running SUM and during any of the phases, it shows errors like below:

         1EETQ399 Last error code set is: Environment variable 'dbms_type' does not exist

         1EETQ204 Upgrade phase "SUMCHK_EXTBUILD" aborted with severe errors ("20200612023423")

        OR

        The command 'SAPuptool' from tool 'SAPuptool' could not be executed successfully

        Upgrade phase "TOOLCHECKXML_DBCLI_2ND" aborted with severe errors

        OR

        Cannot locate 'hdbuserstore' in path '/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/sbin''

        OR

        Error: the command 'disp+work' from tool 'disp+work' could not be executed.

• The Environment variables are correctly maintained for <sid>adm and you can see the same when you run "env" command, however, the SUM tool is unable to read them. This can be checked in the SUM log file ENVDUMP.LOG. If you are able to see all the correct environment variables when you run "env" command but not in ENVDUMP.log or ENVDUMP.SAV file in <SUM>/abap/log directory, it means that SUM is unable to get the environment variables correctly.

• Manually running the command "/usr/sap/hostctrl/exe/saphostexec -userenv <SID>ADM" reports the error :

         "found by SU but not in SHELL: dbms_type=HDB"
