5.5.6 Module sgesap/mdminstance – SAP MDM repositories
The sgesap/mdminstance module is based on sgesap/sapinstance with additional attributes for
MDM repositories, MDM access strings, and MDM credentials. Many configurations combine the
MDM instances like MDS, MDIS, and MDSS (and possibly a DB instance) into one SGeSAP
package. This is called a "MDM Central" or "MDM Central System" installation. Each instance
can also be configured into separate packages, called a "distributed MDM" installation. All MDM
repositories defined in the package configuration are automatically mounted and loaded from the
database, after the MDM server processes started successfully.
The following table contains some selected SGeSAP parameters relevant to a MDM Central System
instance. For more information, see the package configuration file.
