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

#cmmakepkg –i modular_pkgname1.ascii -m ecmt/oracle/oracle -t
haoracle.conf modular_pkgname2.ascii
2. Include the Metrocluster Continuous Access EVA module into this modular package configuration
file.
Use the following command to include Metrocluster module.
#cmmakepkg –i modular_pkgname2.ascii -m dts/mccaeva
The new modular package configuration file will contain the dts/dts/dts_pkg_dir attribute
unassigned.
3. Locate the Metrocluster environment file directory and add this as the value to the
dts/dts/dts_pkg_dir attribute in the package configuration file.
dts/dts/dts_pkg_dir /etc/cmcluster/pkgA
4. Halt the package.
#cmhaltpkg pkgA
5. Apply the package configuration with the modular configuration file.
# cmapplyconf –P modular_pkgname2.ascii
6. Run the package in the Serviceguard cluster.
#cmrunpkg pkgA
With this procedure, the migration is complete for the Metrocluster Continuous Access EVA package
using the Oracle toolkit.
Configuring Modular Packages using Metrocluster with Continuous Access EVA A.05.00 or Later
When configuring Modular packages using Metrocluster with Continuous Access EVA A.05.00
or later, only the package configuration file needs to be edited. All parameters that were previously
available in the Metrocluster environment file are now configured from the package configuration
file. The Metrocluster environment file is automatically generated on all nodes in the directory
specified with the dts/dts/dts_pkg_dir parameter when the package configuration is applied in
the cluster.
CAUTION: Do not delete the Metrocluster environment file that is generated. This file is crucial
for Metrocluster operations.
Complete the following procedure to create Modular packages using Metrocluster with Continuous
Access EVA A.05.00 or later:
1. Run the following command to create a Metrocluster Continuous Access EVA Modular package
configuration file:
# cmmakepkg –m dts/mccaeva temp.config
2. Edit the following attributes in the temp.config file:
a. dts/dts/dts_pkg_dir — This is the package directory for this Metrocluster Modular package.
The Metrocluster Environment file is generated for this package in this directory. This value
must be unique for all packages.
b. DT_APPLICATION_STARTUP_POLICY — This is a parameter used to define a policy for
starting an application. It can be set to Availability_Preferred or
Data_Currency_Preferred policy.
c. DR_GROUP_NAME— This is the name of the DR group used by the
dts/dts/dts_pkg_dir package.
d. DC1_STORAGE_WORLD_WIDE_NAME— This is the World Wide Name of the EVA
storage system that resides in Data Center 1.
e. DC1_SMIS_LIST— This is a list of management servers that reside in Data Center 1.
