New version now available with the following changes:

• Import into USER namespace so the data is stored in USER so there is no need to change CACHELIB to RW.
• The RanRead processes will not start until all the processes have started so they’ll all kick off the iterations at the same time.


Try using apt-get instead of yum. e.g.

# Get basic dependencies, update OS

RUN apt-get update && apt-get install -
    rsyslog \
    which \
    tar \ 
    hostname \
    net-tools \
    wget \
 && rm -rf /var/lib/apt/lists/*


Hi Yuriy,

That's right, the purpose of the Random Read Tool is to simply return a metric to compare storage throughput and not to determine overall DB performance. When looking at the overall performance of the DB a lot of other factors come into play. Check out these great long read articles on understanding and analysing performance:

Hi Evgeny,

Yes, you can import into an OTHERNAMESPACE and map the package to the %ALL namespace. As a test I created the %ALL namespace then imported the PerfTools.RanRead.xml into the USER namespace. Next I created a package mapping in the %ALL namespace to the PerfTools.RandRead class in the USER database. Then I ran the tool in %SYS as documented above and it tested ok.
