NEW QUESTION 4

You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI object storage. Recently, you notice a failed database backup status in the console.
What step can you take to determine the cause of the backup failure?

• A. Ensure that your database host can connect to OCI object storage.
• B. Ensure the database archiving mode is set to NOARCHIVELOG.
• C. Make sure that the database is not active and running while the backup is in progress.
• D. Don't restart the dcsagent program even if it has a status of stop/waiting.

Answer: A

Explanation:
Database backups can fail for various reasons. Typically, a backup fails because either the database host cannot access the object store, or there are problems on the host or with the database configuration.
First need to determining the Problem
In the Console, a failed database backup either displays a status of Failed or hangs in the Backup in Progress or Creating state. If the error message does not contain enough information to point you to a solution, you can use the database CLI and log files to gather more data. Then, refer to the applicable section in this topic for a solution.
Database Service Agent Issues
Your Oracle Cloud Infrastructure Database makes use of an agent framework to allow you to manage your database through the cloud platform. Occasionally you might need to restart the dcsagent program if it has the status of stop/waiting to resolve a backup failure.
Object Store Connectivity Issues
Backing up your database to Oracle Cloud Infrastructure Object Storage requires that the host can connect to the applicable Swift endpoint. You can test this connectivity by using a Swift user.
Host Issues
One or more of the following conditions on the database host can cause backups to fail:
- Interactive Commands in the Oracle Profile
- The File System Is Full
- Incorrect Version of the Oracle Database Cloud Backup Module
- Changes to the Site Profile File (glogin.sql)
Database Issues
An improper database state or configuration can lead to failed backups.
- Database Not Running During Backup
- Archiving Mode Set to NOARCHIVELOG (When you provision a new database, the archiving mode is set to ARCHIVELOG by default. This is the required archiving mode for backup operations)
- Stuck Database Archiver Process and Backup Failures
- Temporary Tablespace Errors
- RMAN Configuration and Backup Failures
- RMAN Retention Policy and Backup Failures
- Loss of Objectstore Wallet File and Backup Failures
TDE Wallet and Backup Failures
- Incorrect TDE Wallet Location Specification
- Incorrect State of the TDE Wallet
- Incorrect Configuration Related to the TDE Wallet
- Missing TDE Wallet File
As this is not new provisioned database and already in the ARCHIVELOG , regular backups of DB system to OCI object storage in places, so the best answers are,
- Ensure that your database host can connect to the OCI object storage
- Restart the database service agent

NEW QUESTION 5

NEW QUESTION 19

You have an application server running in a public subnet on a compute instance in US West (us-phoenix-1) region of Oracle Cloud Infrastructure (OCI). The data sitting on this instance needs to be copied to OCI Object storage bucket available in the same region without traversing over the internet. To enable the connectivity between the instance and Object Storage, you created a service gateway with service CIDR of all Object Storage in us-phoenix-1 enabled.

What could be the possible reason for this behavior?

• A. The route table associated with the subnet has no route rule where the destination is object storage service
• B. The service gateway created in the VCN resides in a different availability domain
• C. The security list associated with the subnet has an egress rule that allows all traffic to be forwarded to a destination CIDR 0.0.0.0/0
• D. Identity and Access Management (IAM) policies restrict the access to the object storage bucket

Answer: A
