first database remains down after install second database
After installation of a second database (Oracle 12.2.0.1.0 - WIN Server 2016), the first instance remains down. "Startup" returns the message that init[instancename].ora is not available.
However, this file exists in the path specified in the message. Also the file spfile[instancename].ora. However a startup by "startup pfile=init[instancename].ora" runs correctly.
Also a "create pfile from spfile" fails with SQLPLUS in this instance. In the instance of the new database this command works correctly as well as the startup-command.
