IBM IMS Physical Organization of Databases — Question 1

A customer is experiencing z/OS performance problems on their z13 while the system is taking a memory dump. Which chargeable z Systems feature could provide relief for this problem?

Answer options

• A. Flash Express
• B. Simultaneous Multithreading
• C. Single Instruction Multiple Data
• D. zEnterprise Data Compression

Correct answer: B

Explanation

Simultaneous Multithreading (SMT) allows multiple threads to run on a single processor core, improving CPU utilization and performance during high-demand tasks like memory dumps. Flash Express provides fast storage, but it doesn't directly enhance CPU efficiency in this scenario. Single Instruction Multiple Data (SIMD) and zEnterprise Data Compression also do not address the specific performance issues related to memory dumps.
