ORA-00307: requested INSTANCE_NUMBER out of range, maximum is [string]
Cause: The initialization parameter INSTANCE_NUMBER specified a number that was out of range.
Action: Change INSTANCE_NUMBER to a valid range and restart the instance. The minimum value is one and the maximum value is the lower of the operating system-specific maximum or the MAXINSTANCES option specified in the CREATE DATABASE statement. See also your operating system-specific Oracle documentation.
