SUM "No synchronization mechanism available" in phase SETSYNC_PREP_STARTED

Hello Gurus,

after we've installed Solution Manager 7.1, we started with the upgrade to SP14 with the current SUM 1.0 SP16 (PL8).

Problem:

In phase SETSYNC_PREP_STARTED in module PREP_INIT we get the error message:

"No synchronization mechanism available"

After researching we came across with the following thread:

https://scn.sap.com/thread/3781598

It seems to us that the colleaque had the same problem. His solution was to use the old method of ./STARTUP with the JAVA view on port 4239 instead of the newer method of ./SUMSTART confighostagent. But i think (or hope) that there must be another solution.

What should we do? Do you have any ideas?

Thanks in advance!

Hello Boris,

we started the upgrade with the wrong URL. We have to use the following URL: http://host:1128/lmsl/sumjava/<SID>/dual.html

Thanks and best regards,

Schady
