Oracle Database 19c: Data Guard Administration Sample Questions (Q85-Q90):NEW QUESTION # 85
Which THREE statements are true........ open in real time query mode, which becomes a new.
  • A. All current buffers can be retained.
  • B. Sessions that are using database links
  • C. All sessions are disconnected and all
  • D. Sessions that have long running queries can be retained.
  • E. User sessions can be retained.
  • F. User sessions and Current Buffers are maintained by default.
Answer: A,C,E
Explanation:
When a physical standby database is opened in real-time query mode, which may be referred to as real-time apply when using Active Data Guard, certain operations can disrupt ongoing sessions. However, with features like Application Continuity and the proper configuration of initialization parameters such as STANDBY_DB_PRESERVE_STATES, user sessions and current buffers may be preserved during role transitions such as a switchover or failover. Specifically, the STANDBY_DB_PRESERVE_STATES parameter can be set to preserve none, all, or only user sessions during such transitions. This ensures that in-flight transactions are not lost and that users do not experience disruptions during the role transitions of a physical standby database.

NEW QUESTION # 86
You detected an unrecoverable archive gap in your data guard environment. So, you need to roll standby.
forward in time without applying a large number of archive log files using this command:
RMAN> RECOVER STANDBY DATABASE FROM SERVICE-<primary database name>;
When running this command, which of the following steps can be performed automatically?
1. Remember all data file names on the standby.
2. Restart standby in nomount.
3. Restore controlfile from primary.
4. Mount standby database.
5. Rename data files from stored standby names.
6. Restore new data files to new names.
7. Recover standby.
  • A. 1,2,3,4,5,6,7
  • B. 1,3,5,6,7
  • C. 2,3,6,7
  • D. 1, 2,3,4,6,7
  • E. 2,3,5,6,7
Answer: D
Explanation:
The RECOVER STANDBY DATABASE FROM SERVICE command in RMAN is designed to automate various steps required to recover the standby database, especially when dealing with an archive gap. When this command is executed, the following actions can occur automatically:
Remember all data file names on the standby (1): RMAN has the capability to recall the names and paths of all data files associated with the standby database.
Restart standby in nomount (2): The standby database can be automatically restarted in the NOMOUNT state, allowing recovery operations to proceed without the database being open.
Restore controlfile from primary (3): RMAN can restore the control file from the primary database to the standby system, ensuring that the standby has the most up-to-date control file.
Mount standby database (4): After restoring the control file, the standby database is mounted to prepare for data file recovery.
Rename data files from stored standby names (5): Not typically done automatically by this command.
Restore new data files to new names (6): New data files added to the primary since the last synchronization can be restored to the standby with their correct names.
Recover standby (7): Finally, RMAN will apply any necessary redo logs to bring the standby database up to date with the primary.
While some steps, such as renaming data files (5), typically require manual intervention or scripting, most of the recovery process can be handled by RMAN automatically, streamlining the recovery of the standby database.

NEW QUESTION # 87
Which FOUR database parameters might be affected by or influence the creation of standby databases?
  • A. STANDBY_ARCHIVE_DEST
  • B. db_file_name_convert
  • C. ARCHIVE_LAG_TARGET
  • D. DB_NAME
  • E. FALSERVER
  • F. COMPATIBLE
Answer: A,B,D,F
Explanation:
* DB_NAME (A): The name of the database, which should remain consistent across the primary and standby databases.
* db_file_name_convert (C): This parameter helps define the mapping of data file names from the primary to the standby database, which is crucial during the creation and operation of a standby database.
* COMPATIBLE (D): The compatibility level can influence the features that can be used on the standby database and must be consistent with or higher than that of the primary database, especially after upgrades.
* STANDBY_ARCHIVE_DEST (F): This parameter specifies the destination of archived redo log files on the standby database, which is important for log transport and apply services.

NEW QUESTION # 88
Your Data Guard environment has two remote physical standby databases.
Client applications use the local naming method to connect to the primary database instance.
You want applications to automatically connect to the new primary database instance in case of a switchover or a failover.
Which set of actions will fulfill this requirement?
  • A. Create a database service on the primary database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.
  • B. Set the INSTANCE NAME parameter identically on all databases; modify the connection descriptor on client applications to include all the standby hosts and connect to the database instance using that service name.
  • C. Set the LOCAL_LISTENER parameter for all the database instance to register services with the default listener on the primary database host.
  • D. Set DB_NAME and DB_UNIQUE_NAME identically on all databases; modify the connection descriptors on client applications to include all the standby hosts and connect to the database instance using that service name.
Answer: A
Explanation:
For seamless client redirection in a Data Guard environment, the following steps should be taken:
Create a database service on the primary database that is started automatically by a trigger when the database role is PRIMARY (B): This ensures that the service is only available on the primary database and is automatically started after a role transition due to switchover or failover.
Modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name (B): Client applications use the connection descriptors that include all potential primary hosts (i.e., the current primary and all standbys). This enables clients to connect to whichever database is currently acting as the primary using the service name.

  • A. Cats will be a disabled physical standby database that can be manually enabled.
  • B. Cats will be an enabled physical standby database.
  • C. Dogs will be the primary database.
  • D. Sheep will be a disabled logical standby database.
  • E. Sheep will be an enabled logical standby database.
Answer: A,C,E
