Oracle Database Errors or Warnings from Error ORA-16627 to ORA-16637

SQLServerF1

ORA-16627: operation disallowed since no standby databases would remain to support protection mode
Cause: This status was returned because of one of the following:
– The broker rejected an attempt to change the overall configuration protection mode since it could not find any enabled standby databases that supported the proposed protection mode.

– The broker rejected an attempt to enable the configuration if it determined that there were no enabled standby databases that supported the overall protection mode.

– The broker rejected an attempt to disable or remove a database that, if disabled or deleted, would result in no remaining standby databases that could support the overall configuration protection mode.

– The broker rejected an attempt to switchover if doing so would violate the overall configuration protection mode.

– Performing automatic health check if the broker determined that no standby datbases supported the overall protection mode.

Action: – If changing the overall protection mode, confirm that at least one standby database satisfies the new protection mode.
– For enable failures, confirm that at least one standby database has a LogXptMode configurable property setting that supports the current overall protection mode.

– For delete and disable failures, confirm that at least one other standby database has a LogXptMode configurable property setting that supports the overall protection mode.

– For switchover failures that occur when the configuration is operating in maximum protection or maximum availability mode, confirm that at least one other standby database has its LogXptMode configurable property set to the value “SYNC”. If the configuration contains a primary database and a single standby database and is operating in either maximum protection or maximum availability mode, ensure that the LogXptMode configurable property of the primary database is set to the value “SYNC”. Since the old primary database will become the standby database after switchover completes, its LogXptMode configurable property setting must support the configuration protection mode.

– For health check error, confirm that at least one standby database has a LogXptMode configurable property setting that supports the current overall protection mode.

ORA-16628: broker protection mode inconsistent with the database setting
Cause: The Data Guard broker protection mode saved in the broker configuration file was inconsistent with the actual database setting.
Action: Reset the protection mode through the Data Guard broker.
ORA-16629: database reports a different protection level from the protection mode
Cause: The actual or current database protection level was different from the configured protection mode. This typically is caused by redo transport problems.
Action: Check the database alert logs and Data Guard broker logs for more details. Also, check the redo transport status. Ensure that one standby database supports the configured protection mode and that the network to that standby database is working properly.

ORA-16630: database property has been deprecated
Cause: The property that was specified in the command was deprecated.
Action: Check the broker documentation to identify a replacement property or SQL command for the deprecated property.
ORA-16631: operation requires shutdown of database or instance “string”
Cause: The Data Guard broker operation required a shutdown of the database or instance.
Action: If database or instance has not been shutdown by the DGMGRL CLI or Enterprise Manager, shutdown the database or instance manually.
ORA-16632: instance being added to database profile
Cause: The Data Guard broker determined that an instance successfully found its database profile within the broker configuration file, but lacked an instance-specific profile. The broker automatically created an instance-specific profile and associated the instance with its database profile.
Action: No user action is required. The broker will automatically associate the instance with its database profile and incorporate the instance into broker activity.

ORA-16633: the only instance of the database cannot be removed
Cause: The instance to be removed was the only instance of the corresponding database that was known to the broker.
Action: Remove the corresponding database object from the broker configuration instead of the individual instance object of the database.
ORA-16635: network connection failed during transmission
Cause: The Data Guard broker detected a connection failure to a remote database in the broker configuration. This failure happened in the middle of a transmission session. A transmission session usually requires more than one send operation for sending a large amount of data (for example, the broker configuration file) to the remote database.
Action: In most cases, no user action is required. The Data Guard broker always tries to resend the data. This error will be reported if the problem persists. This error indicates there are some problems with the network connection between broker managed databases. Further network troubleshooting should be done to identify and correct the actual problem.
ORA-16636: fast-start failover target standby in error state, cannot stop observer
Cause: A STOP OBSERVER operation could not be completed when fast-start failover was enabled because the target standby database could not participate in the STOP OBSERVER operation.
Action: Additional information about this failure is recorded in the Data Guard broker log file for the primary database. This information helps to identify the reason why the target standby database was unable to participate in the STOP OBSERVER operation. If the problem can be corrected by the information in the broker log file, retry the operation. Alternatively, fast-start failover may be forcibly disabled by connecting to the primary database and issuing the DISABLE FAST_START FAILOVER FORCE command from the DGMGRL CLI. Once fast-start failover has been forcibly disabled, the observer can be stopped regardless of the current state of the target standby database.
ORA-16637: an instance failed to access the Data Guard broker configuration
Cause: The broker could not access the broker configuration files on one or more database instances. This can happen when the DG_BROKER_CONFIG_FILE[1|2] initialization parameter values are not to the same set of file locations for a RAC database.
Action: Shut off the broker by setting the DG_BROKER_START initialization parameter to false. Then set the DG_BROKER_CONFIG_FILE1 and DG_BROKER_CONFIG_FILE2 initialization parameters to file locations that are shared by all instances of a RAC database. Finally, restart the broker by setting the DG_BROKER_START initialization parameter to true.
