Plural: online_logfiles, primary_roles
Toward the bottom of page
LOG_ARCHIVE_DEST_n Parameter Attributes
I see the values for the valid_for attribute of log_archive_dest_n:
ONLINE_LOGFILE | |
STANDBY_LOGFILE | |
ALL_LOGFILES | |
PRIMARY_ROLE | |
STANDBY_ROLE | |
ALL_ROLES |
But some documents such as
Creating a Physical Standby Database
has ONLINE_LOGFILES instead of ONLINE_LOGFILE. Some of my standby databases have plural even for primary_roles, by accident I'm sure. At least one such database has gone through a switchover with its standby without any issue.
I'll change all the plural words that should be singular to singular. But I wonder if anyone else has seen this. I'm guessing Oracle supports both but only documents one.
