	MDSS and MDIS do not require a virtual IP address.
MDM_PASSWORD=""	The password used to access MDM.
MDM_REPOSITORY_SPEC=" PRODUCT_HA:MDM:o:mdm:sap \	The following a brief description of the values:

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.

The following table details the MDM_MGROUPand MDM_MASTER dependencies.

Table 5-4 MDM_MGROUP and MDM_MASTER dependencies

Dependency Description

MDM_MGROUP_DEPEND="\ mdb mds mdis mdss" The elements (mdb mds...) of variable MDM_MGROUP_DEPEND are the names of the MDM components that are started from a single Serviceguard package. The order of the MDM components is important.

MDM_MASTER_DEPEND="\ mdbMDM mdsMDM mdisMDM\	Each element (mdbMDM mdsMDM...) of variable
mdssMDM"	MDM_MASTER_DEPEND is the name of a Serviceguard package to
	start. The position of the element determines the start order.

Setup Step: MDM242

(a) Single Serviceguard package - configure sap.config

Edit sap.config and add the following parameters for a Single Serviceguard package configuration. This is for the mgroupMDM package. The key variable for this configuration is MDM_MGROUP_DEPEND="mdb mds mdis mdss".

vi/etc/cmcluster/MDM/sap.config

MDM_DB=ORACLE MDM_DB_SID=MDM MDM_DB_ADMIN=oramdm

MDM_LISTENER_NAME="LISTENER"

MDM_USER=mdmuser
