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.

The initial setup is straightforward, provided you know the source, target, data version and format. You need to consider all those things. First and foremost, when deploying Oracle Data Guard, the number one priority is to ensure all parameters are correctly set. Two primary methods exist: using backups or recovering from services if the network is reliable. If the network is robust, backups from the source to the target may not be necessary. You must ensure that NIS names are correctly configured on both sides and that the failover and switchover processes are tested successfully from both production and standby environments. Once these steps are completed, the deployment process becomes straightforward. There's no need to copy the entire parameter file; only specific configurations, such as the SID or file structure, must be adjusted if necessary. Ensuring proper DNS name resolution, SID configurations, parameter settings, and understanding whether to convert the Data Guard are essential. Once these aspects are identified, the deployment process becomes more straightforward. I have implemented numerous Data Guard setups. Setting up Oracle Data Guard is performed within the Oracle CRS. Challenges may arise in establishing connectivity between the standby and production databases, necessitating troubleshooting. Apart from that, once configured within CRS, the setup is complete. The challenge with Oracle Data Guard is that it often takes some time for us to identify whether the issues stem from the disk or the network. If we report issues to the network or storage teams from the database end, we may not perceive any apparent problems, which can lead to confusion. We can convince the storage teams to investigate further until we delve into the disk I/O Guard and determine if specific disks operate at total capacity. When disks are operating at total capacity, it can significantly impact application processes. These difficulties in pinpointing the source of issues contribute to the challenges of maintaining and managing Oracle Data Guard.

For Italian medium-sized companies, the main challenge lies in the cost associated with licenses. In certain situations, we cannot utilize Data Guard swiftly for executing specific queries or statements that require temporary data manipulation. This is because opening the Data Guard system involves serving the changes and rolling back, even though snapshot features are available. In such scenarios, when customers need to test new application features or in the event of system vulnerabilities, it might be preferable to operate Data Guard without resorting to snapshot or flashback functionalities, thereby avoiding the need to recreate the system or start from a backup. These challenges were encountered within a high-traffic environment.

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

Room for Improvement

"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."
"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."
"The only difficult part is the cost factor, licensing.Another area of improvement is support."
