How often the check/monitor gets executed.MDM_MONITOR_INTERVAL=60
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
DescriptionDependency
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_MGROUP_DEPEND="\ mdb mds mdis mdss"
Each element (mdbMDM mdsMDM...) of variable
MDM_MASTER_DEPEND is the name of a Serviceguard package to
start. The position of the element determines the start order.
MDM_MASTER_DEPEND="\ mdbMDM mdsMDM mdisMDM\
mdssMDM"
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"
