Upgrading your trial license for replication for Db2

You can upgrade your Db2 trial license for replication to a permanent license.

1. Encode your Db2 license to base64 by running the following command:

   LICENSE_KEY="./idr4a.lic"
   cat license_key | base64 | tr -d '\n'

   Save the encoded output, as you will add it to your YAML file later in this procedure.
2. Log in to your Db2 cluster and use the command line interface (CLI) to get the name of your db2ucluster instance:

   # oc get db2ucluster
   NAME                          STATE   AGE            Ready   1d
   db2-16360427332670605
   # INSTANCE_NAME="db2-16360427332670605"

3. Edit the instance.

   oc edit db2ucluster instance_name

4. In edit mode, locate the license key under spec in the YAML file and add the encoded string from step 1 as a value key, as shown below:

   qrep:
         enabled: true
         infraHost: db2-cluster-hostname
         infraIP: db2-cluster-external-ip
         license:
           accept: true
           value: base64_encoded_qrep_permanent_license_string

5. Save and close the YAML file.

   # oc edit db2ucluster instance_name
   db2ucluster.db2u.databases.ibm.com/db2-16360427332670605 edited

6. Scale down the replication pod to 0:

   oc scale --replicas=0 deployment c-instance_name-qrep

7. After the replication pod stops, scale up the replication pod to 1 for the new license to take effect:

   oc scale --replicas=1 deployment c-instance_name-qrep

8. When the new replication pod is ready, verify the updated replication license:

   oc exec -it c-instance_name-repl_instance_name -- su - db2inst1 -c "/opt/ibm/db2/V11.5.0.0/adm/db2licm -l"
