Reviewing MIMIX IBM i Protection Reports

Reviewing your MIMIX protection reports is very important for your MIMIX HA solution. You may have all your data groups synced and your audit reports are running clean but if you are missing replication on libraries and objects you need then you will have issues if you need to switch.

You can access the protection report through the precisely AUI interface. You will sign-on and look at the Analysis tab and this will show you libraries, directories, and folders status of replication. The goal is to have no libraries or objects that are not in a NONE status.…

Startup Program for MIMIX

Here’s a command for your startup program for MIMIX to determine if you are on the source or target:

MIMIX/RTVSYSDFN SYSDFN(*LOCAL) RTNSYSDFN(&LCLSYS)

When you are running MIMIX, you want to have two startup programs for your source and target. You do not want to start all your applications on your target but certainly do on your source.

You can use one program with the command above and then it will determine which system and will run the correct startup program automatically. This MIMIX command will give you the local system name defined MIMIX, so it will know if you are switched and run the correct startup program.

You can then run your startup program once you are switched and it will start all the applications you have in the startup program. This will also stop MIMIX from replacing your startup program since they will always be the same on both sides and then will execute the correct program.…

8 Important Tips for Upgrading your MIMIX Environment

Here are 8 helpful hints for upgrading your MIMIX environment. It is important to keep you MIMIX environment update to ensure you are replicating properly.

One of the most important things with any upgrade is to determine compatibility between the OS and the releases of 3rd party software. MIMIX is no different, and this chart shows you which versions of MIMIX are compatible with which versions of IBM i.…

Planning for the Unplanned: Understanding IBM i Business Continuity

If the unplanned were to happen, do you know how long it would take to recover your system?

[Webinar] Combining HA and Security to Keep Data Safe and Operations Running Smoothly

 

Combining High Availability with Security to Protect Your Data

Join Pete Massiello from iTech Solutions and Becky Hjellming from Syncsort, a leader in IBM i high availability and security, as they discuss the challenges companies struggle with when protecting data from downtime and breach and share their perspectives on solutions to common issues.

[WATCH RECORDING]

Data is the bedrock of your business. It is the foundation upon which your business runs. Losing access to your data due to regional outages, hardware failures or simply human error can have severe consequences to your bottom line. And data breaches can ruin your organization’s reputation and subject it to fines from industry and governmental regulations.

Protecting your business’ critical IBM i data from downtime and breach requires a combination of powerful high availability, disaster recovery and security solutions.…

Replication Role switch/swaps vs Virtual

I have performed many swaps or switches for replication software for the IBM i and a question I hear often is “What is the difference between a swap/switches and a Virtual one?” 

The feature of the virtual role switch/swap is a very useful tool. This allows you to switch your environment and allows validation testing on your target environment without impacting any of your users on your source system. There is no downtime and you can validate your data without having to update your network.

You may have applications you cannot test during a virtual swap but there’s still a good way to test your data and find issues. During a virtual swap, the only replication is ended. Mimix/ iTera keeps track of all changes that were made on the target during the virtual swap and once you swap back, you will undo any changes made to the target.

Journals will still be capturing the source system activity during this time and will be applied to the target once the virtual swap completes. The swap back time will depend on the amount of changes that were made during the testing during the virtual swap. This will be something you want to factor into your plan for any virtual swap.  This is the best way to do destructive testing because during a virtual swap no data will be replicated back to your source system.

Replication role swap simulates the event of a true disaster in the event that your source system is unavailable. This will have the users utilizing the target and any changes will be synced back to your source system.  This demonstrates that if you lost your system users, you would be able to work on the target. Once you got a source available again, the changes can be synced back with limited downtime. You can circumvent the sync back to production by saving your data before the swap on both source and target, restoring them back after testing is completed. You will need to regenerate your journals and restart the data groups from the new journals after the restore is completed on both sides. This would only be for destructive testing and is best to be done during a virtual swap.  

I would recommend a planned swap four times a year, one full swap and three virtual swaps. Three times a year, you can validate your data and …

How to Eliminate Downtime and Keep Business Flowing

According to a study done by Emerson Network Power, 71% of senior-level managers believe that their datacenter is crucial to their company’s success. CEO’s and IT Directors can agree that downtime is a major detriment to business performance, as well as a drain on company budgets. In the same study, Emerson predicted that companies lose an average of $505,500.00 per every 90 minutes of downtime, and sometimes as much as $5,600.00 per minute.

Downtime negatively affects almost every aspect of a business, but for many IT Departments, especially those lacking the needed resources and expert knowledge, maintaining stable system performance can sometimes feel like an uphill battle.

There is a way, however, that IT Departments can essentially eliminate downtime all together, and that’s by implementing high availability and disaster recovery (HADR) solutions. With the ability to keep the essential parts of an infrastructure functioning, such as servers, business-critical applications, and storage systems, businesses can now reap the rewards of uninterrupted business service.

Beyond seamless service capabilities, HADR solutions also offer companies flexible growth and system-wide scalability. Unlike older server environments and disaster recovery systems, HADR supports heavy application workloads while simultaneously maintaining critical data, thus ensuring a company’s sustained productivity.

Paired with cloud and virtual servers, HADR solutions can also help companies recover faster from downtime by having a replicated system already in place.  When a system or server fails, for instance, pre-defined procedures can be laid out and executed to role-swap to servers in the cloud – servers that already have your data fully replicated.

Overall, as companies rely more and more on their IT infrastructures to drive performance, as well as business-wide growth, additional plans and technologies need to be put into place to guarantee the long-term operation and productivity of the entire organization. HADR solutions answer this need with flying colors and a great option for companies looking to alleviate costly downtime.
