Installing Cognos Analytics

An instance administrator can install Cognos Analytics on IBM Cloud Pak® for Data Version 4.8.

Who needs to complete this task?

Instance administrator To install Cognos Analytics, you must be an instance administrator. An instance administrator has permission to install software in the following projects:

The operators project for the instance

The operators for this instance of Cloud Pak for Data are installed in the operators project.

In the installation commands, the ${PROJECT_CPD_INST_OPERATORS} environment variable refers to the operators project.

The operands project for the instance

The Cloud Pak for Data control plane and the services for this instance of Cloud Pak for Data are installed in the operands project.

In the installation commands, the ${PROJECT_CPD_INST_OPERANDS} environment variable refers to the operands project.

The tethered projects for the instance

After you install Cognos Analytics, you can deploy Cognos Analytics service instances to the operands project or to projects that are tethered to the operands project.

When do you need to complete this task?

Review the following options to determine whether you need to complete this task:

  • If you want to install the Cloud Pak for Data control plane and one or more services at the same time, follow the process in Installing an instance of Cloud Pak for Data instead.
  • If you didn't install Cognos Analytics when you installed the Cloud Pak for Data control plane, complete this task to add Cognos Analytics to your environment.

    Repeat as needed If you are responsible for multiple instances of Cloud Pak for Data, you can repeat this task to install more instances of Cognos Analytics on the cluster.

Information you need to complete this task

Review the following information before you install Cognos Analytics:

Version requirements

All of the components that are associated with an instance of Cloud Pak for Data must be installed at the same release. For example, if the Cloud Pak for Data control plane is installed at Version 4.8.5, you must install Cognos Analytics at Version 4.8.5.

Environment variables

The commands in this task use environment variables so that you can run the commands exactly as written.

  • If you don't have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task. For example, run:
    source ./cpd_vars.sh
Security context constraint

Cognos Analytics works with the default Red Hat® OpenShift® Container Platform security context constraint, restricted-v2.

Common core services

Cognos Analytics requires the Cloud Pak for Data common core services.

If the common core services are not installed in the operands project for the instance, the common core services are automatically installed when you install Cognos Analytics. The common core services installation increases the amount of time the installation takes to complete.

Storage requirements
You must specify storage classes when you install Cognos Analytics. The following storage classes are recommended. However, if you don't use these storage classes on your cluster, ensure that you specify a storage class with an equivalent definition.

* indicates that the storage class is used only if common core services needs to be installed.

Before you begin

This task assumes that the following prerequisites are met:

Prerequisite Where to find more information
The cluster meets the minimum requirements for installing Cognos Analytics. If this task is not complete, see System requirements.
The workstation from which you will run the installation is set up as a client workstation and includes the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift CLI: oc
 If this task is not complete, see Setting up a client workstation.
The Cloud Pak for Data control plane is installed. If this task is not complete, see Installing an instance of Cloud Pak for Data.
For environments that use a private container registry, such as air-gapped environments, the Cognos Analytics software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.
For environments that use a private container registry, such as air-gapped environments, the cpd-cli is configured to pull the olm-utils-v2 image from the private container registry. If this task is not complete, see Pulling the olm-utils-v2 image from the private container registry.

Procedure

Complete the following tasks to install Cognos Analytics:

  1. Installing the service
  2. Validating the installation
  3. What to do next

Installing the service

To install Cognos Analytics:

  1. Log the cpd-cli in to the Red Hat OpenShift Container Platform cluster:
    ${CPDM_OC_LOGIN}
    Remember: CPDM_OC_LOGIN is an alias for the cpd-cli manage login-to-ocp command.
  2. Run the following command to create the required OLM objects for Cognos Analytics in the operators project for the instance:
    cpd-cli manage apply-olm \
--release=${VERSION} \
--cpd_operator_ns=${PROJECT_CPD_INST_OPERATORS} \
--components=cognos_analytics
    Wait for the cpd-cli to return the following message before you proceed to the next step:
    [SUCCESS]... The apply-olm command ran successfully

    If the apply-olm fails, see Troubleshooting the apply-olm command during installation or upgrade.

  3. Create the custom resource for Cognos Analytics.
