Assure MIMIX from Precisely (formerly Syncsort) offers IBM i high availability (HA) and disaster recovery (DR) for companies worldwide, from small businesses to global enterprises, who can use Assure MIMIX to prevent data loss and eliminate planned and unplanned downtime. Assure MIMIX provides scalable real-time replication with options for automating administration, monitoring and alerting, customizable switch automation, and a graphical…
Oracle [GoldenGate] is well suited for data replication where real-time results are important, such as data reporting. There is potential to have the users query the replicated database, which can have separate resources set up to be compressed or using lower performing or cheaper resources. As mentioned, columns with LOBs can become a headache, as they will need to be synchronized in their own group many times. Tables containing data in CHAR, VARCHAR, NUMBER, DATE, or other non-LOB columns, however, are able to be replicated quite seamlessly. [Oracle GoldenGate] does provide a way to review errors that are encountered, so that is a positive if their is scrutiny around data integrity.
MIMIX is well suited when the organization requires a PLANNED Switch. MIMX will also work for any unplanned switches. However, this is not the most ideal situation and we have had to perform at least once when the older iSeries hardware failed, and the business transactions were on hold, impacting the business. MIMIX support was required to be called upon to assist. We were able to get the new iSeries online within an hour, so thankfully the outage to the business was miminal. It is important that any organization utilizing MIMIX schedule, prepare, and plan for the PLANNED Switch, at least once per year, if not twice per year.
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.
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
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.
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.
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.
Oracle is tightly integrated with Oracle Exadata and is a better fit for using Oracle databases.Both products support heterogeneous databases but using Exadata, it just seemed to make better sense to use the Oracle GoldenGate product. We also take advantage of the Oracle GoldenGate Veridata product to compare datasets and make sure they are still in sync.
Iterra is a less capable "little brother" product to MIMIX. Iterra like MIMIX was acquired by Vision, then subsequent owning organizations, now Precisely. Most of the original core Iterra functionality has been rolled into MIMIX. The Iterra product still exists but in a very limited role. Precisely and the previous owner has been very clear in their recommendation to standardize on MIMIX.
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.
Oracle GoldenGate guarantees our standing-by database in passive data center, is always in "pre-warmed" status, as the data is always in-sync with the master database in our active data center. At any time, the standing-by database can kick in in case the active DC encounters the serious issue. This significantly increases the IT application's high availability and promise to "business as usual".
Having an HA/DR solution in place is viewed as a positive by customers and potential customers for the marketing of the organization's core products and services.
