Ensures high availability, disaster recovery, and data protection for Oracle databases through features like real-time data synchronization, automatic failover and zero data loss

Oracle Data Guard stands out by providing heavy-duty features that enable connecting multiple standby databases to a single production database. Oracle supports up to eight standby databases, offering a level of redundancy and scalability that other platforms cannot match. Implementing Oracle Data Guard ensures the protection and integrity of your data, even in the event of a disaster. With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations. Data Guard offers multiple protection modes, each serving different needs. One such mode is active-active, where both the production and standby databases are actively accessible. In the event of a failure, seamless switchover occurs without disrupting client sessions, as they remain unaware of the transition between databases.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."

"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."

"It's a very good solution if you want to protect your data across two data centers, or you have a middle man or many administrators who use these solutions for protecting their data. It's very reliable compared to other solutions that are most often not storage-based."

"We have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product."

"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."

"The solution has been stable so far."

"The solution can scale as needed."

"We have found the replication feature the most useful. We use this feature the most. The ability to recover a database with less effort and the use of Oracle Data Guard Broker to administer the complete environment are also very useful features."

More Oracle Data Guard pros

"We did performance testing. We had a set of real life MicroStrategy reports. Our conditions were: Not allowed to redesign data model, not allowed to rewrite the queries, all queries should be generated by MicroStrategy, no aggregates. Teradata appeared to be way faster than a similarly configured (in terms of hardware) Oracle server."

"The initial setup was straightforward."

"The most valuable feature is the ease of uploading data from multiple sources."

"The most valuable features are the Shared-nothing architecture and data protection functionality."

"It effectively has allowed us to remove over 20 portion copies of the data sets on other DB platforms for real-time operational reporting purposes."

"Teradata combines a powerful parallel process and optimizing SQL engine with a highly scalable architecture allowing businesses to execute complex queries and analytics in real-time."

"Teradata's MPP feature allowed the team to handle huge data sets on the scale of petabytes and perform analytics on those in near real-time when users queried for that data."

"Teradata can be deployed on-premise, on the cloud, or in a virtual machine, which means customers can move without having to create their architecture all over again."

More Teradata pros

Cons

"One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle."

"The initial setup is complex."

"The database administration needs improvement. With Oracle, we have a lot of features for administrating data, but it might be too many. It needs to be simplified. It should be automated. Looking at Enterprise Manager, there are too many KPIs in place."

"Oracle could be improved by the ability to manage it on the cloud. This on-premises version is secure and reliable, but I'm sure that they will soon provide a cloud solution that will be even better. In one to two years, we will probably move to the cloud—we have already moved to the cloud with Microsoft Exchange, but our databases are still on-premises. I would prefer managing a cloud version of Oracle."

"They may need to include the monitoring and the alerting part in Data Guard."

"The usage of block storage devices in the cloud or migration of a type of storage from one site to another site can be improved. Currently, we have to use multi-node to single node because of the lack of storage support on the Azure side. It did not really work. Our DBA had to spend a lot of time tweaking the Data Guard tools, or the underlying Oracle VMs, to make sure that Data Guard would run on top of different types of storage. So, if it can support transporting or getting from one type of storage to another type of storage in a different site or a different technology, it would be very helpful."

"The implementation is complex for anyone who's jumping into it without any experience. It's all command-line driven implementations. For some, that's a turn-off."

"We would like to be able to see the date time stamp when you execute DGMGRL commands."

More Oracle Data Guard cons

"Teradata is somewhat late in adopting cloud technology."

"From my perspective, it would be good if they gave better ITIN/R plugins to use the data for AI modeling, or data science modeling. We can do it now; however, it could be more elegant in terms of interfacing."

"I think the UI is not there yet. It could be improved by being more user-friendly."

"Teradata hardly supports unstructured data or semi-structured data"

"One challenge I have faced regarding the main use case is the integration with AI, as Teradata does not have the AI models that other OLAP systems such as BigQuery provide, making it difficult for us to give proper recommendations without using different tools for AI integration."

"The primary challenge with Teradata lies in its cost structure, encompassing subscription fees, software licenses, and hardware expenses."

"I choose 8 out of 10 for Teradata because there is always the scope for improvement."

"The cost of Teradata Cloud Data Warehouse has room for improvement."

More Teradata cons

Pricing and Cost Advice

"It's a cost-effective solution."

"Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."

"The cost of the Oracle license will depend on the negotiations with Oracle."

"This is the best solution if you want something similar that's less expensive than Oracle Grid."

"If you want to have everything automated and done smoothly, you have to add additional licenses."

"The licensing cost is significantly high."

"The cost is expensive."

"The pricing is on the higher side."

More Oracle Data Guard pricing and cost advice

"Price is quite high, so if it is really possible to use other solutions (e.g. you do not have strict requirements for performance and huge data volumes), it might be better to look at alternatives from the RDBMS world."

"The price of Teradata is expensive. However, what they deliver they are outstanding. If you're looking for an inexpensive solution to run a database, this isn't your tool. It's the Ferrari of databases for data warehousing."

"The cost is significantly high."

"The cost of running Teradata is quite high, but you get a good return on investment."

"We had a lot of parties involved when purchasing from the AWS Marketplace. They are very flexible and aggressive in trying to close the deal. They are good at what they have to offer and listening to the customer. It's a two-way street."

"We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise."

"Teradata is currently making improvements in this area."

"It's a very expensive product."
