What is Oracle Data Guard?

Oracle Data Guard ensures high availability, data protection, and disaster recovery for enterprise data. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions. Data Guard can be used with traditional backup, restoration, and cluster techniques to provide a high level of data protection and data availability.

The monitor can predict if you have any issues or develop actions to find a solution

What is our primary use case?

Data focus is the main issue. Most of the features of a new database still go to an Oracle administration section.

Pros and Cons

  • "Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."
  • "Oracle Data Guard is stable, but you need to keep monitoring the system all the time. You need to keep monitoring the archives."

What other advice do I have?

Keep monitoring. This is the problem with the product. You have to keep monitoring the system all the time, just to avoid the interruption from the archive mode. I am going to give Oracle Data Guard a seven out of ten. It still needs improvements. When you are doing the troubleshooting there are no monitoring tools. You have to keep watching the log all the time. Also, for the configuration, if you miss one of the backlogs, you have to re-issue again. Re-issuing is not easy. It's a long process to do it.

Ensures data protection and reduces backup overhead, when set up well

What is our primary use case?

Oracle Data Guard ensures data protection and disaster recovery. The better way to configure Data Guard is by having an Oracle production database on one site as the primary database, and an Oracle standby database on another site. This solution provides high availability.

Pros and Cons

  • "If you have a problem with your primary site and can't access your primary database, you can continue working with the database that you have as standby on the other site, by changing its role to primary."
  • "Another valuable feature is the possibility of backing up the database from the standby database instead of the primary database, to avoid backup process overhead in the primary system."
  • "I think it would be great to have a graphical interface assistant (like DBCA, ASMCA, NETCA, etc.) for initial configuration, monitoring, configuring Oracle Data Guard Broker and all the Data Guard Broker commands, without needing Oracle Enterprise Manager Cloud Control installed."

We've experienced no issues with performance.

What other advice do I have?

It’s the backbone. Nobody interacts with it, it's only the DBAs who use it I think. Once you set it up it's pretty much done. You don't deal with it on a daily basis. Maybe not all products are up to the speed or like any product you take, there is space to improve. I think for our company, the way we use it, we are very happy with it and the end customer is very happy with it.
