How are Abend-AID and IBM Fault Analyzer licensed?

Both diagnose mainframe abends and both are licensed on capacity, but through different vehicles. Compuware (BMC) Abend-AID, now part of the BMC AMI DevX suite, is licensed on MIPS or MSU capacity, commonly inside a wider BMC AMI portfolio agreement, with BMC moving its mainframe portfolio toward a consumption oriented model. IBM Fault Analyzer is part of the IBM Application Delivery Foundation for z/OS family, licensed under IBM's IPLA model as a one time charge plus annual subscription and support, priced on the capacity tier of the machine. So both scale with capacity; the meaningful difference is which vendor's bundle and contract framework you are negotiating inside.

Is it worth switching between Abend-AID and IBM Fault Analyzer?

Sometimes, because the switching cost here is moderate rather than extreme. Fault diagnosis tools are woven into operations runbooks, support procedures, and developer habits, but they do not hold production data or mediate transactions, so a move is more feasible than switching a database or a security manager. The usual driver is the bundle: Fault Analyzer is attractive when you already license the IBM Application Delivery Foundation tools, and Abend-AID is attractive when you run the broader BMC AMI DevX suite. The most reliable value is still leverage, since IBM and BMC each pursue displacement of the other in mainframe tooling.

What actually decides Abend-AID vs IBM Fault Analyzer cost?

Three things decide it more than the feature list. First, the bundle each sits in: Abend-AID inside a BMC AMI DevX portfolio deal versus Fault Analyzer inside the IBM Application Delivery Foundation for z/OS family, where the real pricing happens. Second, the contract model: BMC capacity or consumption against IBM IPLA one time charge plus subscription and support, which behave very differently over a multi year horizon. Third, your incumbency and a credible, prepared alternative, since the tools are close enough in function that licensing structure and leverage, not capability, drive the number.

Abend-AID vs IBM Fault Analyzer: Cost

Abend-AID vs IBM Fault Analyzer: the bundle decides, not the feature list.

Compuware (BMC) Abend-AID and IBM Fault Analyzer both diagnose mainframe abends, and both are licensed on capacity. Abend-AID rides in the BMC AMI DevX suite on MIPS or MSU; Fault Analyzer rides in the IBM Application Delivery Foundation family under IPLA. Feature parity is close, so the bundle each sits in and your incumbency decide the cost.

Follow the bundle, then use the other as leverage. Abend-AID and Fault Analyzer diagnose abends well enough that capability rarely settles it. What does settle it is which suite you already license: Fault Analyzer is the natural choice inside the IBM Application Delivery Foundation for z/OS tools, and Abend-AID is the natural choice inside the broader BMC AMI DevX suite. The switching cost is moderate, not extreme, since these tools sit beside operations rather than inside production data, so a move is feasible where the bundle economics justify it. And because IBM and BMC each chase displacement of the other, a prepared evaluation of the alternative is genuine leverage at renewal either way.

For most estates the bundle you already run points the way. Use it this way:

Lean toward IBM Fault Analyzer if

You already license the IBM Application Delivery Foundation for z/OS tools and can fold it into that family
You prefer the IPLA one time charge plus subscription and support shape over a recurring capacity charge
You are consolidating developer tooling into the IBM stack for support and integration reasons

Lean toward Abend-AID if

You run the broader BMC AMI DevX suite and gain from keeping fault diagnosis inside it
The BMC capacity or consumption model fits your estate better over the renewal horizon
Your developers rely on Abend-AID workflows that would be costly to rebuild

Either way, the first lever is the same as for any capacity priced tool: validate the licensed MIPS or MSU against the systems that genuinely need it, decide the contract model deliberately, and hold a prepared alternative as leverage in the incumbent's renewal.

How are they licensed?Both on capacity. Abend-AID on MIPS or MSU inside the BMC AMI DevX suite; Fault Analyzer under IBM IPLA, one time charge plus subscription and support, inside ADFz.

Is switching worth it?Sometimes, since the switching cost is moderate. The driver is usually the bundle, with the alternative valuable as leverage because each vendor pursues displacement.

What decides the cost?The bundle each sits in, the contract model (BMC capacity or consumption versus IBM IPLA), and your incumbency plus a credible alternative.

What is the first lever?Validate the licensed MIPS or MSU against the systems that need it, choose the contract model deliberately, and prepare the alternative as leverage.

Close on features. The deal is won in the bundle and the leverage.
