Upgrading the trial license for replication in the Db2 Warehouse service

You can upgrade the trial license for replication in the Db2 Warehouse service to a permanent license.

About this task

Run the steps of this task on the Db2 Warehouse cluster host.

Procedure

Log in to your Db2 Warehouse cluster host, scp your Replication license (not the Db2 Warehouse license) to the cluster host name, and generate the encode output by running the following commands:
```
cd <replication_license_directory>
```
```
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.
Use the OpenShift® command line interface (oc) to get the name of your db2ucluster instance:
```
oc get db2ucluster
```
An example output result looks like the following:
```
NAME                          STATE   AGE            Ready   1d
db2wh-16360427332670605
```
Create an environment variable for the db2ucluster instance name by running the following command:
```
INSTANCE_NAME="db2wh-16360427332670605"
```
Edit the Db2U cluster instance YAML file.

Note: The vi editor is used.
```
oc edit db2ucluster ${INSTANCE_NAME}
```

Inside Db2U cluster instance YAML file, locate the

spec: > addOns: > qrep: >
license:

section, insert a key named value with the encoded replication license string as the key value:


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

Save and close the YAML file.

oc edit db2ucluster ${INSTANCE_NAME}

An example output result looks like the following:

db2ucluster.db2u.databases.ibm.com/db2wh-16360427332670605 edited

Scale down the replication pod to 0:

oc scale --replicas=0 deployment c-${INSTANCE_NAME}-qrep

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
```

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"
