OCI-01620

no public threads are available for mounting

Cause

The INIT.ORA parameter "thread" is zero, its default value. There are no threads which have been publicly enabled, and not mounted.


Action

Shutdown the instance, change the INIT.ORA parameter to a thread which is privately enabled and not mounted. If the database is open in another instance, then a thread may be publicly enabled.
