is it supported configuration (TimesTen x64 on Win Server 2012 x64) ?
I am experiencing some problems during data store creation - "838: cannot get data store shared-memory segment, error 5"
(also there problems with TT net service starting but it could be solved by changing registry keys permissions)
11.2.2. has not been certified on Win 2012. See here
for supported platforms.
What client are you using to initiate the data store creation e.g ttIsql making a first connection, ttAdmin -ramLoad etc? I have seen one report of a customer using ODP.NET client and also getting this error 5 on Win 2012 but an answer has not been found. This is hampered by the simple fact that TT hasn't been tested or certified on Win 2012.
