- A
Reduce the number of HANA services.
Why wrong: Reducing services may impact functionality; not the first step.
- B
Upgrade the instance to a larger memory-optimized type.
Why wrong: This is a longer-term solution; first try adjusting existing resources.
- C
Increase the HANA memory allocation parameter in the global.ini file.
Adjusting the memory allocation can reduce pressure without changing instance type.
- D
Increase the swap space on the instance.
Why wrong: Swap is slower than RAM; this may degrade performance further.
Question 8 of 1,733
SAP HANA Memory Tuning — Increase Allocation in global.ini
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SAP system is experiencing slow performance. The SAP team suspects a memory bottleneck in the HANA database. The database runs on an r5.24xlarge instance with 768 GB RAM. CloudWatch metrics show the HANA memory usage is consistently above 90%. Which action should be taken first?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the HANA memory allocation parameter in the global.ini file.
Option C is correct because the HANA database may have a memory allocation parameter that is lower than the available physical memory, causing a bottleneck even when RAM is available. Increasing this parameter in the global.ini file allows HANA to use more memory, addressing the issue without scaling up. Option A is wrong because reducing HANA services does not directly increase memory availability for the database; it may reduce workload but not the memory bottleneck. Option B is wrong because upgrading the instance is a more disruptive and costly step that should be considered only after tuning parameters. Option D is wrong because swap space is much slower than RAM and is a temporary fix, not a solution for a persistent memory bottleneck.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
