Once installed OBIEE 12c SampleAppv511 successfully as its guide instructed on a Windows 7 host with 16 Gb RAM, and started the Database service, however, it is not possible to start the bi_server1 service, basically, this starting service runs forever, I tried to wait for a full day but this never started, and the VM hangs forever. I increased the VM RAM available from 6.2 Gb (as suggested by VM guide) until 12 Gb, but this didn't sort out this behavior.
Did anybody hit against this issue? or Were you able to work with this VM?
