Building Disaster Recovery Serviceguard Solutions Using Metrocluster with EMC SRDF

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.
To start the disaster tolerant RAC database:
1. Run the cmviewcl command to view the disaster tolerant RAC database configuration in a
Metrocluster.
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
SITE_NAME san_jose
NODE STATUS STATE
SJC_1 up running
SJC_2 up running
MULTI_NODE_PACKAGES
PACKAGE STATUS STATE AUTO_RUN SYSTEM
SG-CFS-pkg up running enabled yes
sfo_crs_dg up running enabled no
sfo_crs_mp up running enabled no
sfo_crs up running enabled no
sjc_crs_dg up running enabled no
sjc_crs_mp up running enabled no
sjc_crs up running enabled no
sfo_hrdb_dg down halted enabled no
sfo_hrdb_mp down halted enabled no
sjc_hrdb_dg down halted enabled no
sjc_hrdb_mp down halted enabled no

sjc_flash_mp down halted enabled no
sfo_hrdb down halted disabled no
sjc_hrdb down halted disabled no
UNOWNED_PACKAGES
PACKAGE STATUS STATE AUTO_RUN NODE

2. Enable all the nodes in the Metrocluster for the Site Controller Package.
# cmmodpkg –e –n SFO_1 –n SFO_2 -n SJC_1 –n SJC_2 hrdb_sc
3. Start the Site Controller Package.
# cmmodpkg -e hrdb_sc
The Site Controller Package along with RAC stack starts up on the local site (Site A).
4. Check the Site Controller Package log file to ensure clean startup.
Configuring client access for Oracle database 10gR2 RAC
In Oracle Database 10gR2 RAC, the Oracle Clusterware configuration provides Virtual IP addresses
(VIPs) through which database clients external to the cluster connect to the database. Oracle listeners
