PowerHA Now Replicates To Multiple Targets Sans SAN

May 8, 2023 Alex Woodie

The new release of PowerHA will enable customers to use geographic mirroring to replicate their IBM i data to two or more targets. That one enhancement brings a host of benefits for customers not using SAN-based storage, including new deployment scenarios using on-prem, cloud, and hybrid topologies, as well as lower downtime for hardware upgrades, mirrored Db2 Mirror pairs, and lower RPO for tape backups.

Prior to PowerHA SystemMirror, most IBM midrange customers who were using high availability (HA) software were using solutions based on logical replication, whereby changes to IBM i data are picked up from the local receiver …

Technology Always Replaces People While Augmenting Others

May 8, 2023 Timothy Prickett Morgan

If there is one rule of technology, it is that technology always replaces some people while augmenting others. And like religion and politics or how much money you make, it was not discussed in polite company. With the advent of machine learning-driven AI and the modern and often impolite world it was born into, this may not be the case anymore. People are talking. IBM among them.

When IBM launched the System/360 mainframe in April 1964, it was a transformative thing for what was yet to become the computer industry. Early on, with the advent of data store and database …

Guru: Speeding Up RPG By Reducing I/O Operations, Part 1

May 8, 2023 Gregory Simmons

Perhaps one of the easiest ways to speed up an RPG program is to reduce the number of I/O operations it needs to perform. In this article let’s explore one simple method for moving toward dataset processing.

Here I have a simple RPG program. Okay, admittedly, we don’t often get to write “simple” RPG programs, but for this example, I have stripped the RPG program down to just the read loop so I can demonstrate the conversion.
```
1     Dcl-f AcctMstr Usage(*Input) Keyed;
2     Dcl-pr entry ExtPgm('RPGRPT1');
3       n Packed(3:0);
4     End-Pr;

5     Dcl-pi entry;
6       inBranch Packed(3:0);
7     End-pi;

Virtual Student Meet And Greets Are Building Momentum – And Futures

May 8, 2023 Laura Ubelhor

As an active member of the COMMON Education Foundation board, education advocate, and active community volunteer, I am often in conversation with organizations seeking to connect with student resources, schools that provide IBM i curriculum, and the IBM i community. These conversations inspired me to organize an informal virtual student meet and greet earlier this year, and to then do a more formal one in the wake of the POWERUp23 conference.

The initial event turned out great and has inspired me further. Many connections were made. The students who are ready to become the next generation on IBM i are …

IBM i PTF Guide, Volume 25, Number 19

May 8, 2023 Doug Bidwell

There are new cumulative updates this week, and a couple of security vulnerabilities that you need to be aware of, which we cover along with the normal PTF updates and defective PTF rundown that we do every week. Let’s start, as we often do, with the vulnerabilities.

First, we have Security Bulletin: IBM WebSphere Application Server Liberty for IBM i. which is vulnerable to a server-side request forgery, a denial of service, an attacker obtaining sensitive information, and gaining elevated privileges due to multiple vulnerabilities. You can find out more about at this link. The issues can be fixed …
