Azhagupandi Parthiban

Vice President Of Technology at a tech services company with 1,001-5,000 employees

Offers near-real-time replication for data consistency and continuously introducing new features through upgrades

There are various advantages. First of all, easy to deploy. The only difficult part is the cost factor, licensing. In other ways, the implementation is very, very important. Like, 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. Once you configure it, it goes through the rollback, and then Data Guard introduces this snapshot thing. So once the restoration happens, we can go back to the original thing, and we make that a standard. It's a pretty decent and key function for Oracle. So, enterprise organizations go for Oracle only for features like these.

Expert Backup at a tech services company with 201-500 employees

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments

Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"We use Data Guard for online replication from data center, to data center for high availability. This is the most important feature."

"The most valuable feature is the application or promotional code used in the production protocol to transfer data to the secondary database, situated on the DR site."

"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."

"The most valuable aspect for me is undoubtedly the failover capability and the assurance of data safety provided by Oracle Data Guard."

"Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced."

"The solution is really very stable. One good thing about it, compared to other products, is that you can just run it and forget about it. Unless you come across some interruptions in the network, it works like a charm."

"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."

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

More Oracle Data Guard pros

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

"I am impressed with the tool's technical alliance with Veeam and Veritas."

Cons

"Sometimes, the technical support team takes time to respond."

"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."

"The product could improve its pricing."

"There is an issue with their application on ODG. There were a lot of edits in the logs. Sometimes, we only get a little cue from the Data Guard Broker logs if there's an issue."

"The predominant issue lies in the communication link between the secondary and primary databases."

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

"Overall, there are some operational issues that need to be dealt with."

"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."

More Oracle Data Guard cons

"The product needs to improve performance while scaling out. It also needs to improve stability."

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

Pricing and Cost Advice

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

"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."

"It's a cost-effective solution."

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

"The licensing cost is significantly high."

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

"The cost is expensive."

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

More Oracle Data Guard pricing and cost advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
