- One required exam, C1000-198, earns the IBM Certified Db2 v12.1 Database Administrator - Professional credential (C9009700).
- IBM targets candidates with at least two years of hands-on Db2 experience, but frames this as guidance, not a gate.
- The exam has 66 questions in 90 minutes, and you need 47 correct answers.
- Operating carries 33% and Monitoring 18%, so most of your readiness must come from those two areas.
What "Requirements" Actually Means for This Exam
Searches for "C1000-198 requirements" usually bundle three different questions: Am I allowed to sit this exam?, Am I ready to pass it?, and What do I need to do on exam day? They have different answers, and mixing them up leads to wasted months or wasted attempts.
This article covers all three for one credential only: the IBM Certified Db2 v12.1 Database Administrator - Professional, which covers Db2 v12.1 for Linux, UNIX and Windows. The credential is listed as C9009700, the single required exam is C1000-198, and both the certification and the exam are listed as Live. If you want a broader orientation first, see What Is C1000-198? or the overview at C1000-198 Certification.
Formal Requirements vs. Recommended Background
The cleanest way to think about qualification is to separate what IBM requires from what IBM recommends.
| Item | Status | What it means for you |
|---|---|---|
| Passing exam C1000-198 | Required | This is the one required exam for the credential. |
| Two or more years of hands-on Db2 experience | Target-candidate guidance | Describes the intended Professional-level candidate; it is not presented as an enforced gate. |
| Recommended IBM courses | Preparation only | They help you study but do not add exam domains or extra required exams. |
| English proficiency | Practical | The exam is delivered in English. |
| Prior IBM certification | Not listed as required | No prerequisite credential appears in the sources reviewed. |
In plain terms: there is one exam to pass, and the experience statement tells you who the exam was written for. If you are earlier in your career, that does not stop you from booking, but it does change how much preparation you should plan. Our look at how hard the C1000-198 exam is explains why the experience profile matters so much.
The Two-Year Hands-On Profile
IBM describes the intended candidate as a Db2 database administrator with at least two years of practical, hands-on experience. Because the exam includes performance-based lab tasks alongside multiple-choice items, that experience is not decorative. Reading about a command is a different skill from knowing which command to run, with which options, in which order, when something is wrong.
What counts as relevant experience
- Installing Db2 v12.1 servers and clients on Linux, UNIX or Windows, and managing instances afterward.
- Creating and altering databases, table spaces, buffer pools, tables and indexes.
- Running routine operations such as backups, data movement and maintenance.
- Diagnosing slow or failing workloads using Db2 monitoring facilities.
- Administering authorities, privileges and auditing.
- Setting up and testing recovery and high availability configurations.
If you are short on experience
Build a lab. A modest Linux virtual machine with a Db2 v12.1 instance is enough to rehearse almost every task the exam objectives name. The goal is repetition of administrative tasks until you do not need to look up syntax. Candidates who have only studied theory tend to stall on the lab-style tasks; candidates with a working instance tend to move through them quickly.
Exam Format and Conditions You Must Meet
Qualifying also means being ready for the conditions under which the exam is delivered. These are the facts to plan around:
- 66 questions in 90 minutes for the whole exam, so roughly 80 seconds per question on average.
- 47 correct answers are required to pass.
- Mixed item types: IBM explicitly includes multiple-choice questions and performance-based lab tasks. The official sample also demonstrates multiple-response items, where more than one option may be correct.
- No separate practical timer: IBM publishes no separate time allowance for the practical portion, so the 90 minutes covers everything.
- Unauthorized reference materials are prohibited. Plan to work from memory and hands-on skill, not from documentation.
- Language: English.

Domain-by-Domain Readiness Checklist
The study guide organizes the exam into six objective sections. The published weights total 100% and are described by IBM as approximate. Use the checklist below as a self-assessment: if you cannot do these things comfortably, you are not yet at the Professional level the exam assumes. For a deeper walkthrough, see C1000-198 Exam Domains: Complete Guide to All 6 Content Areas.
Domain 4: Operating (33%)
The heaviest section by a wide margin, and the one where lab-style competence pays off most.
- Create and manage databases and the objects inside them.
- Run and verify day-to-day maintenance and data movement operations.
- Work comfortably at the command line and with Db2 commands and SQL administration tasks.
- Recognize the effect of configuration choices on running workloads.
Domain 3: Monitoring (18%)
The second-largest section. It rewards candidates who have actually chased down a performance problem.
- Know which monitoring facilities to use for which symptom.
- Interpret monitoring output to find contention, slow statements or resource pressure.
- Connect what you observe to a corrective administrative action.
Domain 5: Security and Compliance (15%)
Access control and accountability for the database environment.
- Authorities and privileges: who can do what, and how that is granted and revoked.
- Controlling access to data and tracking activity for compliance purposes.
- Understanding how security choices affect both users and administrators.
Domain 6: Business continuity (14%)
Protecting data and keeping the database available.
- Backup and recovery concepts and when each approach applies.
- High availability and disaster recovery configuration at a conceptual and practical level.
- Choosing a continuity approach for a described business requirement.
Domain 2: Db2 Server and Client Installation and Management (11%)
Getting Db2 onto systems and keeping instances healthy.
- Install, configure and manage Db2 servers and clients.
- Manage instances and their configuration over time.
Domain 1: Design and Architecture (9%)
The smallest section, covering how Db2 environments are structured.
- Understand the architecture and design considerations behind a Db2 deployment.
- Make sound structural decisions before objects are built.
One naming note: the detailed study guide PDF labels Domain 1 as "Design and Architecture", while IBM's web summary says "Design and Architect". Both refer to the same 9% section, so do not worry if you see both wordings.
Registration, Delivery and Retake Rules
Once you decide you are ready, these are the mechanics to know before you click anything.
Booking and delivery
The testing provider is Pearson VUE, operating under the IBM Professional Certification Program. IBM program delivery options include test centers and OnVUE online proctoring, but the options actually offered for this exact exam are shown at booking, so confirm what is available to you in your region before planning around either one. For timing and scheduling considerations, see C1000-198 Exam Dates: Testing Windows, Deadlines & Scheduling.
Fees
The retrieved sources did not verify a current certification-exam fee, and they gave no population pass rate, so this article does not quote either. One caution: the USD 30 figure that appears in the study guide applies to a separate assessment exam, not to C1000-198. Check the fee displayed at booking, and see C1000-198 Certification Cost: Complete Pricing Breakdown for how to budget.
Retake policy
- At most two attempts at the same exam within any 30-day period.
- Retakes are charged at the regular retake price.
- You cannot retake an exam you have already passed.
Continuing validity of the credential is governed by IBM's Certification Agreement, so read it after you pass rather than assuming terms from other vendors.
Key Takeaway
Because retakes cost the regular price and cluster limits apply, treat your first attempt as the one that counts. Book only when your lab work in Operating and Monitoring is fluent, not merely familiar.
A Qualification Plan Built Around the Weights
The only generic planning advice this article offers is this: let the domain weights dictate your calendar. Operating and Monitoring together make up 51% of the approximate weighting, so they deserve the most hours and the earliest start. The plan below assumes you already have some Db2 administration exposure; stretch it if you are building experience from scratch. A fuller approach is in the C1000-198 Study Guide: How to Pass on Your First Attempt.
Operating (33%)
- Stand up a Db2 v12.1 lab instance and build a database from scratch.
- Repeat core administrative tasks until you can do them without notes.
- Practice multiple-response style questions on operational scenarios.
Monitoring (18%)
- Generate load in your lab and observe it with Db2 monitoring facilities.
- Practice reading output and naming the likely cause and fix.
Security and Compliance (15%) and Business continuity (14%)
- Configure authorities and privileges, then verify what each user can and cannot do.
- Rehearse backup, restore and recovery, and review high availability concepts.
Installation (11%), Design (9%) and review
- Reinstall or reconfigure an instance to cement Domain 2 skills.
- Review architecture and design decisions.
- Take timed mixed sets to practice the 90-minute pace.
When you are ready to test yourself under realistic pacing, our C1000-198 practice tests mirror the mixed-format feel, and the C1000-198 Cheat Sheet is a handy final-week refresher.
Who Hires for This Credential
A Db2 v12.1 DBA credential is most relevant to organizations that run Db2 for Linux, UNIX and Windows in production: large enterprises with long-lived transactional and reporting systems, IBM-aligned consultancies and managed-service providers, and internal infrastructure teams that support business-critical applications. Typical titles include Db2 database administrator, database engineer, and database operations or reliability roles with Db2 responsibilities.
The credential signals that you can handle the full administrative lifecycle: installing, operating, monitoring, securing and protecting a Db2 environment. It does not replace experience, and employers will usually still probe your hands-on history.
