Check License Limits

This article explains how check the limits and validity of an uploaded license.

You can check the details of an uploaded license using ConfD. This operation is not available in the Administration API.

Connect to COS

Connect to EXAClusterOS (COS) using c4 connect -t <DEPLOYMENT>[.<NODE>]/cos. For example:

./c4 connect -t 1/cos

For more information about how to use c4 connect, see How to use c4.

View license details

To view details about the currently installed license, use the ConfD job license_info. For example:

confd_client license_info

  comment: Unlimited license with an expiration date.
  company_name: Exasol

Limits:
  max_db_mem_size_in_gb: Unlimited
  max_db_raw_data_size_in_gb: Unlimited
  max_nodes_per_cluster: Unlimited
  max_num_clusters: Unlimited

Limits:

max_db_mem_size_in_gb

Previously used for licenses based on database RAM. This license type is deprecated and the parameter value is always “Unlimited”.

max_db_raw_data_size_in_gb

The maximum size of raw data in GiB that you can store across all databases in the cluster. The raw data volume corresponds to the data volume that is comparable to the size the data would have if stored as CSV files.

Audit data is not counted towards the raw data license limit.

For more details about how raw data size is determined, see Sizing for Data Types and Object Types.

max_num_clusters

The maximum number of running clusters allowed by the license.

Clusters are counted per database. This means that n databases will count as n clusters, even if all databases run on the same set of nodes.

max_nodes_per_cluster

The maximum number of active nodes on a running cluster. Access node and standby nodes are not counted towards this limit.

Check license

To verify that the currently running databases do not exceed the license limits, use the ConfD job license_run_check. If the command returns OK, you are within the limits of your license.

confd_client license_run_check
OK
