Robot | Navigating your HA/DR Options for IBM i

Not satisfied with your HA tool? It could be time for a switch. Get the guide: https://www.helpsystems.com/cta/how-shrink-high-availability-overhead-ibmi

The high availability landscape for IBM i continues to evolve. What was once a simple, one-player logical replication market is now a diverse mix of solutions, including IBM’s PowerHA and Db2 Mirror for i, along with several software-based replication solutions from third-party vendors.

Given the importance of HA/DR for business continuity, it is essential that you have the right tool for the task. But what are your options and how do you know which will work best in your environment?

During this webinar, IBM Champions for Power Systems Brian Nordland and Tom Huntington will discuss the different types of data replication available for IBM i and where it makes sense to combine solutions. You’ll learn:

-The current HA/DR options available
-Pros and Cons of each solution
-A better understanding of the HA/DR coverage
-The best method for your environment: Logical Replication, PowerHA, Full System Replication (FSR), DB2 Mirror for i, FlashCopy, or a combination

Whether you’re looking to implement an IBM i high availability, improve your DR abilities, have lost confidence in your current solution, or are simply bringing yourself up to speed with the current methods of achieving HA/DR, this webinar offers a technical explanation of the options available for IBM i.

Defective PTF can impact heavy users of Save While Active (SWA)

Abstract

Certain defective PTFs can allow a Heap Segment Storage leak when Save While Active (SWA) is used. Heavy SWA usage can lead to the system running out of this resource, exposing performance problems or even a termination of the operating system.

Content

The following defective PTFs are involved:

7.3: MF70440 (or supersedes MF70600 or MF70677)

7.4: MF70546 (or supersede MF70674)

7.5: MF70552 (or supersede MF70675)

With one of those PTFs applied, each instance of Save While Active (SWA) that ends can leave 9 segments of Resident Heap allocated.  While there are hundreds of thousands of these segments available to the OS, the allocation leak can accumulate quickly in environments that rely heavily on SWA.  The eventual impact can involve performance problems, and potentially lead to a partition termination, when the heap storage is exhausted.

It is recommended to apply the fixing PTFs, especially if your environment uses SWA regularly.

Fixing PTFs (contain the fix for this issue and the other issues addressed by the earlier, now defective PTFs):

7.3: MF70736

7.4: MF70758

7.5: MF70757

Application options:

Temp apply the fixing PTF(s) – Pro: This is the easiest option.  Con: This will push the defective PTF(s) to the A side.  In general the systems should not run on A side, and if they do, it’s not usually for very long.  So, there is limited risk of encountering the issue if you have to run on A side.
Perm apply the fixing PTF(s) – Pro: This will push the fixing code to the A and B side.  This is a good option if you already have one of the defective PTFs applied permanently.  Con: Requires an IPL to apply Perm.
Remove the defective PTF(s) and temp apply the fixing PTF(s) – Pro: This will not push the defective PTF(s) to the A side.  Con: If one of the defective PTFs is already applied Perm, then this does not fix the A side.  Again, there is limited risk of encountering the issue if you have to run on A side and one of the defective PTFs is applied Perm.
