hostname requirement
Hostname Requirement
  • Production and standby sites are in completely separate networks and the fully qualified hostnames can be the same in both sites
  • Or, production and standby sites have different DNS that resolves the hostnames to the right IP in their network
    • The standby site can have standby DNS that is activated on a disaster event
  • Or, production hostnames are resolved to local IP address in standby site via /etc/hosts file
configure dr environment
Configure DR Environment
  • Install and Configure Primary Site
    • Binaries and Data should be on a replicated partition
    • Do not distribute services between servers that are not clustered
  • If hostnames are to be different in standby site, setup hostname aliases in Standby Site
  • Install and Configure Standby Site
  • Setup Database Replication
    • Backup & restore is ok
  • Setup Disk Replication
    • Backup & restore is ok
  • Enable Standby Site
install and configure standby site
Install and Configure Standby Site
  • Install and configure in both production & standby site

HyperionHome for each server is in a separate directory; it should be a network share or mount point in the servers

Note: BI+ repository and Essbase App directories should be in a common share across machines, e.g. under /data

setup hostname aliases
Setup Hostname Aliases
  • If the hostnames have to be different between the two sites and there is no separate DNS for standby site, setup alias for production site servers in the standby site in the following way.

/etc/hosts entries in standby site; order of server entries is important

10.2.1.111 server1 drserver1

10.2.1.112 server2 drserver2

10.2.1.113 server3 drserver3

10.2.1.114 dbserverdrdbserver

database recommendations
Database Recommendations
  • Use DB Host Name alias on Standby Site
  • Data Guard Configuration for data repositories
  • For planned configuration changes, force database synchronization with Oracle Data Guard
  • A backup & restore procedure will also work
setup disk replication
Setup Disk Replication
  • Enable disk replication
    • A backup & restore procedure will also work

Enable Replication

enabling standby site
Enabling Standby Site
  • Break mirroring between primary and standby.
  • Run Crash Recovery Procedure for each application
    • Recover OpenLDAP
    • Recover Essbase
  • Bring up the services on the standby hosts
