Managing Serviceguard Extension for SAP, December 2007

SAP Master Data Management (MDM)
Installation and Configuration Considerations
Chapter 5288
MDM can be configured to run as "SINGLE" or “ONE” Serviceguard
package OR as "MULTIPLE" or “FOUR+ONE” Serviceguard packages.
In the case of a "SINGLE" package all MDM components (mdb mds mdis
mdss) are always started and stopped on the same cluster node which
the Serviceguard package itself is started on. In this case variable
MDM_MGROUP_DEPEND will be used by the Serviceguard package called
(mgroupMDM) to start these in order.
In the case of "MULTIPLE" Serviceguard packages each MDM
component (mdb or mds or mdis or mdss) is configured as a separate
Serviceguard package (mdbMDM mdsMDM mdisMDM mdssMDM) and can be
started independent of the location of the other MDM Serviceguard
packages. Variable MDM_MASTER_DEPEND controls this configuration and
is used by a "FIFTH" Serviceguard package called (masterMDM) to start
these in order.
