Oracle GoldenGate vs. Precisely Assure MIMIX

I think it's a great product. We apply Oracle GoldenGate to several use cases in our organization. 1. Business Continuity Planning, 2. Query Offloading through data replication to a reporting instance of our data, 3. looking into data transformations to help support various queries for different teams within the business.

MIMIX is clearly the best IBMi solution for most high availability and disaster recovery situations. It provides rock-solid replication and agile ability to switch quickly. In its earlier days, some organizations used it as a primary daily system backup method. With the advent of Ransomware, this is no longer advisable. The strength of MIMIX real-time replication becomes a weakness if IBMi data becomes infected. As in any real-time replication product, at that point, two systems are infected.

• As the product under the Oracle umbrella, it perfectly and natively supports the Oracle database very well.
• For the standard scenario and use cases, the configuration is straight-forward (in our case uni-direction copy from source to target).
• It is robust and the performance meets our SLA, even for a large amount of data volume.
• The error report is not only detailed but hits the right points, so trouble shooting is easy.

Incentivized

• Redundancy - needs to be available at a moment's notice.
• Protection - the business would be greatly impacted, therefore protection of production systems is key to the business succeeding.
• Usability - needs to be user-friendly, easy to navigate and operate, as it will be required at any given time.

• The earlier versions of Golden Gate were complex to use as there was no front end. All that works was the command line.
• The cost of the product can be a detriment to most companies.
• The product has been augmented over the years and has so many features that it can be overwhelming.

• Possible false sense of security for ransomware attacks.

Oracle GoldenGate is a core part of our business.

Once set up, it's very easy to use and keep running, it's getting to that point that can make it cumbersome to some. Also, depending on the data that you want to replicate, the configuration files can become quite cumbersome to maintain. Learning curve can be high for some who are not as experienced with databases and transactions.

Oracle GoldenGate has only gone down for us when the data being sent was bad.

MIMIX is software built for availability. By its nature it is must be available. As long as the underlying system and communication network are available MIMIX is working. And if there are failures in either of those, MIMIX is designed to allow for a quick and resilient recovery once underly systems or communications are restored

Oracle GoldenGate's performance is great for our use cases. Your mileage may vary.

Incentivized

I have never seen MIMIX itself be a performance bottleneck. However it is important to consider the network in overall performance of any remotely replicated systems. MIMIX can only replicate as fast as the network allows. But a strong capability of MIMIX is its ability to "buffer" its replication, so it can be sent without error as the network allows

Oracle Support for Oracle GoldenGate has been quite responsive and quite helpful in the few situations where we've needed it. Furthermore, the documentation on Oracle GoldenGate is so good that we often do not need to contact support with issues as the fix is already documented and able to be run by us without needing to open a ticket.

Incentivized

Support is available and efficient. Response time is good and likelyhood of a quick resolutiion is high. However the mature solid product and proactive management tools, fortunately make support requirements relatively rare. The support for version upgrades is also strong, but again the basic upgrade process is usually straightforward and well documented.

We've had Oracle consultants come as well for training days to talk about new features, parts of Oracle GoldenGate we may not be using and things of that nature. The consultants they send are great as they're very knowledgeable about all things Oracle GoldenGate and great resources for any questions or concerns you may have with the product.

We used Oracle University for our Oracle Golden Gate Training and it was top notch. We were able to turn our whole DBA team to Oracle GoldenGate newbies to Oracle GoldenGate troubleshooting experts in a matter of a few days, while this obviously did not come cheap, the company felt that it was worth the investment.

Incentivized

If Oracle GoldenGate is new to your organization, expose as many DBAs as possible to it. Having your whole team fluent in it will overcome early operational hurdles and allow it to more quickly become an accepted and supported part of your supported platform for your team that will enable the business to use it to its fullest.

We use Oracle Data Guard as a backup tool, but not for data replication. Data Guard is not suited for real-time data replication in our non-normalized reporting database nor for the database we are using for our upgrade project, as Data Guard is not able to transform data and is not able to synchronize data into different schemas, which is necessary for our project. Additionally, our project database is on Oracle 12g not 11i: I am not 100% sure Data Guard is able to replicate from 11i to 12g

We used MIMIX for its role for iSeries high availability. We used Double Take by Vision Solutions for our production Windows environment. MIMIX is designed for iSeries, and Double Take was designed for Windows. We had VMware virtual environment, running multiple VMs for production ERP Lawson M3, now Infor. Both MIMIX and Double Take played the role well for what needed to be done. Without either MIMIX or DoubleTake, the business would have been impacted.

Have never had any issues with scaling Oracle GoldenGate itself, however Oracle GoldenGate Monitor does have scaling issues, but with Oracle GoldenGate now able to be monitored by Oracle Enterprise Manager, this is no longer an issue, in my opinion.

MIMIX works to its intended functionality. It provides real time data replication across multiple partitions and systems as defined. I have never witnessed any problems with MIMIX in scaling to larger systems or adding new data groups. In conjunction with the inherent scalability of IBMi scalability and configuration flexibillity are rather quick and easy.

• In earlier versions, DDL support was limited as well as the need of primary key constraints in the source tables. This made me create partitions, sub-partitions, truncatations and perform other operations upon they are performed in source systems and I need to discuss with source system administrators and need to convince them to let them create primary keys for replicated tables.
• But both issues are solved now.
• Installation is straightforward, easy.
• Deployed everything within Oracle Data Integrator.
• Developing 1000 of ODI interfaces for loading into Operational Data Store took not more than 100 man/days. But, adding them to Golden Gate is taking not more than 5 man/days.
• Management Pack and VeriData are additional packs for your management and data verification needs.

Incentivized

• MIMIX had a positive impact, as the organization has had to rely upon the unplanned switch.
• MIMIX definite must if organization is running i Series, and business needs are 24/7.
• Without MIMIX in place, the downtime impact to the business would have been great.
