Introduction

This blog is part of a series to help you pass the SAP Certified Technology Associate – SAP HANA 2.0 certification exam, C_HANATEC_13.

For an overview of the exam, see

For the sample questions, see

Topic Areas

There are 10 topic areas and you can expect about 8 questions for each topic.

On my exam – but your mileage may vary – I only had 4 questions give or take categorized as MDC. However, when counting all questions that included a reference to multitenancy, the count came to 20. In other words, a quarter of the exam tests your knowledge on this topic. Make sure you master it!

In this blog, I will discuss the Multitenant Database Containers (MDC) topic.

On the SAP Training website for C_HANATEC_13, the exam objective for this topic is stated:

Explain the SAP HANA Multitenant Database Containers 
architecture and understand the differences in 
database administration and backup and recovery. 

Study Material

The study material for this topic comes from training

You can download the index of the guide with the units and lesson objectives from the SAP Training website.

There is no dedicated unit on MDC. The topic is included in the units about architecture, deployment options, backup and recovery, and security.

This topic is also addressed in the following SAP HANA guide:

Multitenant Database Containers (MDC)

Not surprising, considering that MDC is a new topic in the C_HANATEC_13 exam, you can expect a fair number of questions about this topic. Make sure you understand the relationship between the system and the tenant database(s), tenant database isolation, port assignment, the web dispatcher (for XS classic), tenants in a distributed system (scaling-out), and single to multitenant conversion.

The following two SAP notes (knowledge base articles) may also provide some useful insights:

The SAP HANA Academy material on this topic was posted in 2015 and needs to be updated but the concepts are still the same:

    Hello  Mr. Denys van Kempen,

    Thank you for your blog series, which is excellent resource and very comprehensive.

     

    I would like to ask a question regarding the MDC. In the documentation it is said that:

     

    The multitenant database container deployment type was introduced with SAP HANA Support Package Stack (SPS) 09, and makes it possible to run several SAP HANA instances on the same hardware in a production environment.

    https://help.sap.com/viewer/2c1988d620e04368aa4103bf26f17727/2.0.00/en-US/6483b71787f2439c907bd99036559e72.html

     

    Are this really different instances? From the definition of the instance it does not seem to be correct; they are really databases, as far as I can understand.

     

    Could you please clarify?

     

    Thanks

      Hi Shkelzen,

      That’s correct. Another way to phrase this could be that ‘it makes it possible to run several SAP HANA databases inside a single instance on the same hardware ... ‘

      You can run multiple SAP HANA systems (instances) on a single server as well, this is referred to as MCOS, see

      Does this answer your question?

      Thanks

      Regards,

      Denys / SAP HANA Academy
