1. Power11 Entry Machines: The Power S1124 And Power L1124

   For several decades, a two-socket server was the workhorse machine in most datacenters, whether they were running a database machine for transaction processing or a scale-out cluster of machines for distributed Web applications and their related back-ends. And for many OS/400 and IBM i shops, the two-socket machine was the one that provided the right balance of compute and storage expansion and density.

   But, over the years, as Power processor cores have gotten more powerful, customers have needed fewer and fewer cores to run their relatively modest (by comparison) and relatively static (they grow along with the business, but not …

2. BRMS Isn’t The Only Backup Product With A Security Problem

   IBM last month patched a serious security flaw in BRMS, the built-in backup and recovery facility that it ships with the IBM i operating system. The flaw is the latest in a series of security flaws uncovered in backup tools, which cyber criminals appear to be now targeting.

   If you’re a regular reader of Doug Bidwell’s IBM i PTF Guide – and really, if you are responsible for managing an IBM i environment, you should be reading it regularly – then you already knew about the security flaw in BRMS. Bidwell covered the flaw and the associated emergency PTF for …

3. Guru: A Faster Way To Sign A JWT

   In my prior article, which you can read here, I discussed using the OpenSSL tool to asymmetrically sign a JWT. I like OpenSSL because it’s an open source solution available on many platforms and easy to use. But the decision to use OpenSSL should be coupled with the performance level expectations (the PLA) for your project.

   For instance, how many tokens will you need to create in a given interval? Will your newly minted tokens expire 24 hours from now or in 5 minutes? In my case currently, only about 5 JWTs are needed per day so …

   Legacy applications are frequent targets for modernization efforts, but databases also need their share of TLC. One company that specializes in database modernization, Maxis Technology, recently announced support for IBM i and its integrated Db2 for i database with its flagship product, dubbed Alchemize.

   Maxis Technology is an Eagle Rock, Missouri, company that specializes in database modernization. Founded by Steve Cornell in 2011, Maxis develops the Alchemize database power tool, which allows developers and engineers to automate a range of database tasks, including: data migration and loading; data mapping and archiving; data transformations and cleanup; fixing data quality issues; optimizing …
