Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA A.05.01

1. Add the EMS resource dependency to all DG MNP packages in the RAC MNP stack on both
sites.
If you have SLVM or Veritas CVM or SG SMS CVM or CFS configured in your environment,
add the EMS resource details in the packages that are the root packages among the workload
packages in both the sites.
resource_name /dts/mcsc/hrdb_sc
resource_polling_interval 120
resource_up_value != DOWN
resource_start automatic
When using SLVM, or VERITAS CVM, or SG SMS CVM/CFS configured as a modular package,
run cmapplyconf to apply the modified package configuration.
2. Verify the Site Safety Latch resource configuration at both sites.
If you have SLVM or Veritas CVM or SG SMS CVM or CFS configured in your environment,
run the following command to view the EMS resource details:
# cmviewcl -v –p <pkg_name>
Modifying Site Controller to manage RAC MNP stack packages
1. Configure the Site Controller Package with 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.
2. 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, configuring SADTA in your environment with the Oracle Database 10gR2 RAC is
complete. This section describes the procedure to start the disaster tolerant RAC database in the
Metrocluster.
To start the disaster tolerant RAC database:
1. Run the cmviewcl command to view the disaster tolerant RAC database configuration in a
Metrocluster.
The following is a sample output:
# cmviewcl
CLUSTER STATUS
dbcluster up
SITE_NAME san_francisco
NODE STATUS STATE
SFO_1 up running
SFO_2 up running
