Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

NOTE: Specify the condition as != DOWN with a space before the word Down. Ignoring the
space will cause the cfsdgadm command to fail.
If you have SLVM configured in your environment, add the EMS resource details in RAC
database package configuration file.
RESOURCE_NAME /dts/mcsc/hrdb_sc
RESOURCE_POLLING_INTERVAL 120
RESOURCE_UP_VALUE != DOWN
RESOURCE_START automatic
You must apply the modified RAC database package configuration using the cmapplyconf
command.
2. Verify the Site Safety Latch resource configuration at both sites.
Run the cfsdgadm ls command.
cfsdgadm show_ems hrdbdg
RESOURCE_NAME /dts/mcsc/hrdb_sc
RESOURCE_POLLING_INTERVAL 40
RESOURCE_UP_VALUE != DOWN
cfsdgadm show_ems flashdg
RESOURCE_NAME /dts/mcsc/hrdb_sc
RESOURCE_POLLING_INTERVAL 40
RESOURCE_UP_VALUE != DOWN
If you have SLVM configured in your environment, run the following command to view the
EMS resource details:
cmviewcl -v –p <rac_pkg_name>
3. Configure the Site Controller Package with the RAC MNP stack packages of both sites.
site san_francisco
critical_package sfo_hrdb
managed_package sfo_hrdb_dg
managed_package sfo_hrdb_mp
managed_package sfo_flash_dg
managed_package sfo_flash_mp
site san_jose
critical_package sjc_hrdb
managed_package sjc_hrdb_dg
managed_package sjc_hrdb_mp
managed_package sjc_flash_dg
managed_package sjc_flash_mp
NOTE: Do not add any comments after specifying the critical and managed packages.
4. Re-apply the Site Controller Package configuration.
cmapplyconf -v -P /etc/cmcluster/hrdb_sc/hrdb_sc.config
After applying the Site Controller Package configuration, run the cmviewcl command to view the
packages that are configured.
Starting the Disaster Tolerant RAC Database in the Metrocluster
At this point, you have completed configuring SADTA in your environment with the Oracle Database
10gR2 RAC. This section describes the procedure to start the disaster tolerant RAC database in
the Metrocluster.
Complete the following procedure to start the disaster tolerant RAC database:
