Precisely Assure MIMIX vs. Redgate SQL Toolbelt Essentials

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.

We use SQL Compare to troubleshoot performance problems quite a bit since our data model is more like a template and not everything is 100% in sync and customization occurs between different client databases. We continually get pulled into performance issues and the developers will say Client A is performing different than Client B, why? Using SQL Compare, we usually find that one client was tuned and had indexes altered or added that weren't deployed to all clients or other objects weren't deployed correctly during the release. On the other hand, since our data model practices allow client databases to drift I tried to create a new golden image by trying to compare multiple databases based on the same data model and found it to be a very difficult process to complete using SQL Compare. SQL Compare gave me too much information and doesn't allow enough filtering to eliminate a lot of the noise.

• 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.

• Simple and easy comparison of database schemas and data. Differences can be copied or synced from one database to another with a click of a button.
• You can save "projects" so that you can easily rerun a previous comparison whenever you need to.
• It has a very simple, easy to learn interface. I've never needed to read any documentation or watch any tutorials in order to figure out how to do something.

• Possible false sense of security for ransomware attacks.

• Pricing.... I wish there was an inexpensive developer version I could buy for myself.
• Portability.... I would like to use it from a flash drive so I can use it where ever I am asked to work.
• Unbundled.... This may be available already but I dont' recall I can buy it cheaply as a stand-alone product. Its only part of the bundle - cost effectively.

It's a good tool to have, but becomes expensive to buy a user license for each developer.

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

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.

They have a great community website where you can search for answers but are also very responsive when it comes to direct support.

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.

I've used Visual Studio Database Projects for this type of work in the past with some success, but Redgate SQL Compare is faster, more transparent, and simply easier to use. Faster is self explanatory. More transparent, means that it's much easier to set up your desired options for schema change deployment scripts. Easier to use, It's really dead simple. Start a project, connect your source, connect destination, click compare.

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.

• 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.

Incentivized

• Makes deployment fairly simple. Cutting our deployment time down.
• With the SDK, we can customize our deployment process very quickly and easily.
• History is not great, it does create scripts you can go back and see but it would be nice to have a quicker version view by object to save time.
