Guides → Upgrade from 4.6, 4.7, or 4.8 to 5.2

Prior to upgrade, please review the Release Model. The Release Model describes the release statuses: Preview and Generally Available. Refer to the Release Model to identify the release version and status that is most suitable for upgrading your Sandbox, Developer, User Acceptance Testing (UAT), or Production environment.

Upgrade Considerations

• Prior to upgrade, this release requires the installation of the Chromium headless browser on all hosts for the Incorta cluster. In addition, all hosts must have adequate disk space for shared storage to support the migration to a new shared storage directory structure. Lastly, if your Incorta cluster has a separate Apache Zookeeper cluster, you must also upgrade Apache Zookeeper.

If you are using CentOS, make sure to run this command: sudo yum install atk java-atk-wrapper at-spi2-atk gtk3 libXt libdrm mesa-libgbm.

• If you are upgrading to 5.2.3 or later, a valid license key is required during the upgrade process. To obtain your license key, please contact Incorta Support.

Upgrade from 4.6, 4.7, or 4.8 to 5.2.x

This guides details how to upgrade a standalone Incorta cluster. Upgrading your Incorta cluster to Release 5.2 requires team resources:

• a System Administrator with root access to the host or hosts running Incorta Nodes, the host running the Cluster Management Console (CMC), and the host or hosts running Apache Spark
• a CMC Administrator
• a Database Administrator
• a Super User that can access each tenant in the Incorta environment
• an Incorta Developer to resolve identified issues with formula expressions, schema alias, joins between tables, and dependencies between objects such as dashboards and business schemas

It also requires time as these general timelines for various procedures and processes indicate:

Prepare for Upgrade Readiness

To prepare for Upgrade Readiness requires:

• a System Administrator with root access to the host or hosts running Incorta Nodes as well as the host running the Cluster Management Console (CMC)
• a CMC Administrator
• a Database Administrator

The estimated time to complete the following is from 15 minutes to 3 hours:

• Pause all scheduled jobs
• Export all tenants
• Add a Create View database grant

Pause all scheduled jobs in the CMC

Enable this setting to pause active scheduled schema loads, dashboards, and data alerts. This is helpful when importing or exporting an existing tenant. Here are the steps to enable this option as default tenant configuration:

• In the Navigation bar, select Clusters.
• In the cluster list, select a Cluster name.
• In the canvas tabs, select Cluster Configurations.
• In the panel tabs, select Default Tenant Configurations.
• In the left pane, select Data Loading.
• Enable the Pause Scheduled Jobs setting.
• Select Save.

Export of all tenants with the Tenant Management Tool

A System Administrator with root access to the host running the Cluster Management Console (CMC) is able to run the Tenant Management Tool (TMT). Here are the steps:

• Secure shell in to the CMC host.
• As the incorta user, navigate to the installation path of the TMT. The default installation path for the TMT is:

<CMC_INSTALLATION_PATH>/IncortaAnalytics/cmc/tmt

• For each tenant in the cluster, create a tenant export file.

Copy
./tmt.sh -clnm <CLUSTER_NAME> --export <TENANT_NAME>  <TENANT_EXPORT>.zip

Example

Copy
./tmt.sh -clnm myIncortaCluster --export myTenant /tmp/myTenant.zip

• As desired, secure copy each tenant export file to your local host.

Add a Create View database grant

A Database Administrator with root access to the MySQL database server that runs the Incorta Metadata database is able to add the Create View database grant. The estimated time to complete the following is from 5 minutes.

MySQL

Here are the steps for MySQL:

• Sign in to the MySQL Incorta metadata database as the root user.

Copy
mysql -h0 -uroot -proot_password incorta_metadata

• Verify the incorta database user for the incorta_metadata database.

Copy
SELECT User, Host FROM mysql.user WHERE user = 'incorta';

• Verify the current grants for all users.

Copy
SHOW GRANTS for 'incorta'@'locahost';
SHOW GRANTS for 'incorta'@'127.0.0.1';
SHOW GRANTS for 'incorta'@'192.168.128.101';

• If needed, add the CREATE VIEW grant to the all incorta users.

Copy
GRANT CREATE VIEW ON `incorta_metadata`.* TO 'incorta'@'localhost';
GRANT CREATE VIEW ON `incorta_metadata`.* TO 'incorta'@'127.0.0.1';
GRANT CREATE VIEW ON `incorta_metadata`.* TO 'incorta'@'192.168.128.101';

Achieve Upgrade Readiness

Please review Concepts → Upgrade Readiness. Achieving Upgrade Readiness requires:

• a System Administrator with root access to the host or hosts running Incorta Nodes as well as the host running the Cluster Management Console (CMC)
• a CMC Administrator
• a Super User that can access each tenant in the Incorta environment
• an Incorta Developer to resolve identified issues with formula expressions

The estimated time to complete the following is from 2 hours to 3 days:

• Resolve alias issues with the Alias Sync Tool
• Resolve issues with formula expressions that the Formula Validation Tool identifies
• Resolve Severity-1 issues that the Inspector Tool identifies

Resolve alias issues with the Alias Sync Tool

Here are the resources required to run the Alias Sync Tool:

• A System Administrator with root access to the host running an Incorta Node is able to run the Alias Sync Tool.

To resolve issues with Alias tables, you must download the alias_sync.py file, secure copy the file to IncortaNode/bin directory, and the run the script for each tenant in your cluster.

To learn more, please review Tools → Alias Sync Tool.

Resolve issues with formula expressions that the Formula Validation Tool identifies

Here are the resources required to run the Formula Validation Tool and identify outstanding issues with formula expressions:

• A CMC Administrator to export tenants in a cluster or a System Administrator who can export tenants using the Tenant Management Tool (TMT).
• A System Administrator with root access to the host running an Incorta Node will need to run the Formula Validation Tool.
• A Super User that can access each tenant in the Incorta environment.
• An Incorta Developer to resolve the identified issues with formula expressions.

For a given tenant export, the Formula Validation Tool checks the formula syntax in dashboards, business schemas, and schemas. For example, the tool identifies issues with formula columns and runtime security filters in a schema table. One such issue is with aggregation formula expressions that are missing commas between input values of the type integers, longs, and doubles. In Release 5.2, commas must separate input parameter values for built-in functions. In previous releases, the Formula Builder accepted spaces between input values. The Formula Validation Tool identifies this and other issues with formula syntax.

To learn more, please review Tools → Formula Validation Tool.

Resolve Severity-1 issues that the Inspector Tool identifies

Here are the resources required to run the Inspector Tool:

• For a given tenant, a CMC Administrator enables the Inspector Tool Scheduler and schedules an Inspector Tools job. A CMC Administrator also downloads the Inspector Tool related schema, business schema, and dashboards files for all tenants.
• A Super User that can access each tenant in the Incorta cluster.
• An Incorta Developer to resolve the identified issues in the 1- Validation UseCases dashboard.

For a given tenant, the Inspector Tool checks the lineage references of Incorta metadata objects including tables, schemas, business schemas, business schema views, dashboards, and session variables. It also checks for inconsistencies and validation errors in joins, tables, views, formulas, and dashboards.

To learn more, please review Tools → Inspector Tool.
