Oracle Coherence vs. Precisely Assure MIMIX

Oracle Coherence can be used to solve latency problems by caching data near the application tier. In-memory performance helps to reduce data contention, thus improving application response time. Oracle Coherence does a great job at scaling linearly and can do so dynamically. Oracle Coherence can replicate data so it can be part of a disaster recovery solution. One thing that is often overlooked with elastic caches is their ability to analyze data in memory, leveraging the processing power of the data grid. This is something Oracle Coherence does exceptionally well. Oracle Coherence also provided event handling capabilities to allow applications to respond to events triggered by transactions.

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.

• Performance. Superfast resolution of complex data grid queries.
• Reliability. Availability domain support for disaster recovery.
• Programming model. Frictionless API for use with Java 8.

• 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.

• I can't really come up with too many flaws, but possibly a bit expensive considering there are good open source caches like Ehcache.

• Possible false sense of security for ransomware attacks.

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 Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.

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.

DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications. On the otherhand Oracle Coherence has more a flexible configuration and better performance. Also the Oracle configuration and monitoring tools are more convenient and informative than the DataSynapse ones.

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.

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 my current project, it is yet to be decided as we are on the way to make it live for users. But I am sure it will be an added value to obtain timely calculations.

• 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.
