iTech Solutions - for all of your IBM i System needs
One of the most frequently asked questions we receive regarding the IBM i OS is, should I upgrade to 7.3 or 7.4? The answer is: it depends. When it comes to deciding whether you should go to 7.3 or 7.4 you have to take dependencies, features and life expectancy into consideration.
Before you decide, you need to verify which IBM i versions your hardware can support. There are dependencies between the hardware you are running and what OS level it can support. If you are limited by your hardware, then you don’t have much choice in the matter. We suggest you upgrade to the highest OS level that is compatible with your Power System.
Many executives talk about moving their business applications off the IBM i. They think the platform is dead, courtesy of the people who have been saying this for the past 20 years. While we know, the platform is open and offers businesses rock-solid availability, reliability, and securability.
They could also be thinking they will save money on hardware. While that may be true, there will be more servers, requiring more space, more electricity, more cooling, and more human resources to support them. In reality, they save nothing and perhaps spend more. And they increase their risk of downtime and security vulnerability.
So, now that you have to deal with the board room decision, what should you do?
With Client Solutions now being the only IBM-supported client software for IBM i, quite a few organizations have made the switch from the old iAccess products or are in the process of doing so. ACS is as flexible as the old application was rigid, and there are many different ways to configure it on a PC. One of the recurring questions we get from clients who are planning the switch relates to controlling what the end-user can see and use within the application. To address this, I’d like to discuss a bit about how ACS does configuration under the hood and how administrators can have some control over what can be accessed within the application.
IBM i 7.3 TR7 and 7.4 TR1 were announced during IBM Tech U and will be generally available on November 16, 2019. This refresh includes many enhancements to improve further the reliability, availability, and security of your IBM i environment. Some of the major enhancements are focused on DB2 Mirror for IBM i, enhancements to help developers modernize, increased security, and support for new hardware.
I’m going to highlight some of the features that improve the security and administration of your system. There are also many enhancements for RDi that will improve developer productivity and allow you to modernize with additional support for Open Source languages and tools. I don’t plan to get into the details of those enhancements in this article, but I will touch on them. You can get more details about all of the enhancements here.
Last month, I talked about how you can make sure your system has the ability to report problems back to IBM in the event of a failure. That functionality can be invaluable for keeping your system running, but what happens if something goes wrong while the OS is still trying to start? What if something fails so far down the hardware stack that the system simply can’t be aware of it before the whole show grinds to a halt? That’s where an HMC has your back, and it can call home to IBM as well.(more…)
On April 23rd, 2019, IBM announced the newest release of the operating system IBM i 7.4. The announcement contained hundreds of updates to the OS and licensed programs.
One new licensed program, DB2 Mirror for i was also announced. It provides continuous availability for IBM i applications. “Continuous Availability” is a new term, which previously we had High Availability.
For the answers to these questions, and more, keep reading.(more…)
Manually Moving the PCI Fiber Channel Adapter/IOA from Partition B to Partition A
Note: Not shown in this process/steps, you will need to check and vary off, if needed, the resource using the physical adapter on Partition B, (i.e., tape library, tape drive), and then vary on the resource that will use the physical adapter on Partition A.
Using the Classic GUI
The enhanced UI does not support dynamic logical partitioning (dlpar) move. The user must first remove the adapter from the current owning partition then add the adapter to the target. The operating system device needs to be “varied off’ prior to removing the adapter from the owning partition.
1. Remove the adapter from current partition.
Select Resources > All partitions.
Select the partition that owns the resource now.
Then, click on the Physical I/O Adapters:
Select the I/O adapter to remove.
Click Action > Remove Adapter.
At the prompt “The selected adapter will be removed. Do you want to continue?” Click OK
Click the Save button at the top of the physical I/O Adapter panel to apply the changes.
This will remove the adapter from the partition.
Note: The device would need to be varied off prior to removing the adapter.
Add the adapter to the target partition.
Select the target partition
Select Physical I/O Adapters:
Click Add Adapter. Select the adapter to add, then click OK:
Click the Save button at the top of the
physical I/O Adapter panel to apply the changes
The IO adapter should now report in to the target partition.
