Hello,

we are investigating to install MDM 7.1 Sp7 with several instances to separate impact in different repositories, but with one database (oracle). Has someone done this kind of installations? Has it improved stability?

Regards,

Alexander Türk

Hi

From MDM 7.1 SP06 and up, multiple instances of MDM are supported on the same MDM host machine.

Each instance must be installed separately and requires a different SID and different listening ports.

Hello,

I do not think, we can have multiple instances of MDM on single machine, you can have different versions.

You can further read the following threads

Hello,

the threads you are referring to are very old. Based on the newest installation 7.1 docu you can install several instances in one database using different SIDs. THe question is, has someone done this already?

Hello,

which document are you referring to.

As far i know, MDM cannot be installed with several instances.

Hello,

This clearly says, it adds a new, but nothing of multiple instances.

For an MDM environment to work, we require three Servers, Master Data Server(MDS), Import Server(MDIS), Syndication Server(MDIS).

MDIS and MDSS run in conjunction with MDS.

This refers to the multiple instances, but in all it will an single installation across environment.

You will have the basic Development, Quality and production, each will have a different installation.

an extract from help.sap.com site

Support for Installing and Running Multiple MDM Server Components on a Single Machine

Starting from MDM 7.1 SP06, you can install and run multiple MDM server components on one physical machine.

One advantage of installing multiple MDM server components on a single machine, as opposed to loading multiple MDM repositories on a single Master Data Server (MDS), is that parallel execution of imports/syndications to/from loaded MDM repositories is possible. Another advantage is that you can have two repositories for separate projects on two different MDM versions on the same machineu2014resulting in reduced TCO. (In previous releases you would be required to separate the repositories on two different MDM servers, and adhere to the recommendation that the Master Data Import Server (MDIS) and Master Data Syndicator Server (MDSS) be run on a separate machine from the Master Data Server (MDS)).

Each Master Data Import Server (MDIS) and Master Data Syndicator Server (MDSS) must be configured to work with one particular MDS only.

You can distribute the MDM server components according to the following hardware configuration options:

● Multiple Master Data Servers on one machine with remote MDM Import/Syndication Servers on a second machine, and a DBMS on a third machine.

● Multiple Master Data Servers and MDM Import/Syndication Servers on one machine with a remote DBMS on a separate machine.

● Multiple Master Data Servers, MDM Import/Syndication Servers, and a DBMS all on one machine.

Test results show that hardware sizing parameters are almost identical for all the aforementioned configuration options; therefore the configuring option you choose should be based solely on your preferred hardware setup.
