Set the license on a node.

Run this command on a running Master Aggregator. A failure message will be displayed if you run this command on a stopped node.

This command runs memsqlctl set-license on a host where the target node is located. If the target node isn't specified, the command will be run for the Master Aggregator node.

The set-license command must have a valid license provided in one of the following ways:

  • As an argument on the command line with the --license flag

  • In the MEMSQL_LICENSE environment variable

  • In a text file, where the filename and its path are passed as a single argument with the --file-path flag

sdb-admin set-license --license AAAAAAa/Aaa/AA==
