Deploying Redundant System Without Starting Any Services

Virtual Appliance can perform a deployment without starting services. The deployment is controlled by a flag file on the file system (/opt/CA/VirtualAppliance/custom/dr_enabled) which must have a single line with value "TRUE".

Virtual Appliance can be deployed without starting any services.
To deploy the Virtual Appliance without starting any services, you must create
dr_enabled
file at
/opt/CA/VirtualAppliance/custom
location and add a single line
TRUE
to the file.
This functionality is relevant for Disaster Recovery sites, which serve as a "hot-standby" for a primary site, with the following assumptions:
  • All the Virtual Appliance servers are part of the same cluster.
  • The
    dr_enabled
    files must be created only on the new servers that will be used for disaster recovery, and not on the existing primary server.
  • The following components in the Disaster Recovery site are continuously replicated from the primary site :
    • User Store
    • Provisioning Directory
    • Database (external implementation by customer or Services)
  • When
    dr_enabled
    is set to
    TRUE
    , none of the following database-dependent services will run on the Database Recovery servers, therefore the Database Recovery servers are essentially in a standby mode.
    • CA Identity Manager
    • CA Identity Governance
    • CA Identity Portal
  • While in standby mode, the Disaster Recovery servers will not be able to write to the database.
  • The database-dependent services on the Disaster Recovery site start
    only
    when the Disaster Recovery site goes LIVE.
