I did not know you could start nodes outside the cluster (with the RUN files) and I am happily surprise that you can, I will keep this in mind.
On the other hand, my database was working properly before upgrade to SP136 and I am, so far, confident it will/is still working properly now.
The problem I face at the moment has nothing to do with the datbase itself but with sybcluster and the agent. Both nodes have agents working properly but still, sybcluster gives me constant errors.
I have a strong feelings the problem resides in SCC33 lacking the correct isntallation/configuration to handle cluster services.
What I did last evening is to create a dummy cluster database using sybcluster wich should create the necessary configuration, in SCC33, to work properly. I did not have the time so far to go through but I will, sometime today, and post back my conclusion.
Thanks for you time and support, really appreciated!
