Prerequisites for configuring the Oracle service group

Last published : Aug 05, 2026
Prerequisites for configuring the Oracle service group are as follows:
  • If you have configured a firewall, add the required services and ports to the Firewall Exception list.
For a detailed list of the required services and ports, see the InfoScale® Installation and Upgrade Guide.
  • Verify that the appropriate InfoScale product is installed on all cluster nodes.
  • Verify a VCS cluster is configured using VCS Cluster Configuration Wizard (VCW).
  • You must be a Cluster Administrator. This user classification is required to create and configure a service group.
  • You must be logged on as a Domain Administrator on the node where you run the wizard.
  • Verify that the InfoScale High Availability Engine (HAD) is running on the system from where you run the wizard.
  • Connect the LUNs or mount the volumes containing the data files, control files, redo log files, bdump, cdump, and udump files. Unmount or disconnect the volumes or LUNs from other nodes in the cluster.
  • Mount the database and start the Oracle instance on the node running the wizard.
  • After the application service group configuration, if you have manually edited any of the resource attributes, then you must reset them to their default values. Failing this, the wizard may fail to identify and populate the resources involved in the service group configuration.
After you modify the service group configuration you can again edit the resource attributes to set the desired value.
  • Keep the following information ready; the wizard will prompt you for this information:
    • The databases and listeners to be monitored by VCS
    • For the instances to be monitored in detail, name and location of the respective SQL files
    • A valid domain name, user name, and password with which the database service was configured for the database
  • If your storage is SCSI-3 compliant and you wish to use SCSI-3 persistent reservations, enable SCSI-3 support using InfoScale Enterprise Administrator (EA).
  • Assign the virtual IP address on the system where you run the wizard. Remove the virtual IP address from other systems.
