e. Delete the OAM domain home

Sometimes in production, but most likely in testing environments, you might want to remove the domain home that is generated using the create-domain.sh script.

  1. Run the following command to delete the domain:

    $ cd $WORKDIR/kubernetes/delete-domain
$ ./delete-weblogic-domain-resources.sh -d <domain_uid>

    For example:

    $ cd $WORKDIR/kubernetes/delete-domain
$ ./delete-weblogic-domain-resources.sh -d accessdomain

  2. Drop the RCU schemas as follows:

    $ kubectl exec -it helper -n <domain_namespace> -- /bin/bash
[oracle@helper ~]$
[oracle@helper ~]$ export CONNECTION_STRING=<db_host.domain>:<db_port>/<service_name>
[oracle@helper ~]$ export RCUPREFIX=<rcu_schema_prefix>
   
/u01/oracle/oracle_common/bin/rcu -silent -dropRepository -databaseType ORACLE -connectString $CONNECTION_STRING \
-dbUser sys -dbRole sysdba -selectDependentsForComponents true -schemaPrefix $RCUPREFIX \
-component MDS -component IAU -component IAU_APPEND -component IAU_VIEWER -component OPSS \
-component WLS -component STB -component OAM -f < /tmp/pwd.txt

    For example:

    $ kubectl exec -it helper -n oamns -- /bin/bash
[oracle@helper ~]$ export CONNECTION_STRING=mydatabasehost.example.com:1521/orcl.example.com
[oracle@helper ~]$ export RCUPREFIX=OAMK8S
/u01/oracle/oracle_common/bin/rcu -silent -dropRepository -databaseType ORACLE -connectString $CONNECTION_STRING \
-dbUser sys -dbRole sysdba -selectDependentsForComponents true -schemaPrefix $RCUPREFIX \
-component MDS -component IAU -component IAU_APPEND -component IAU_VIEWER -component OPSS \
-component WLS -component STB -component OAM -f < /tmp/pwd.txt

  3. Delete the contents of the persistent volume, for example:

    $ rm -rf <workdir>/accessdomainpv/*

    For example:

    $ rm -rf /scratch/OAMK8S/accessdomainpv/*

  4. Delete the WebLogic Kubernetes Operator, by running the following command:

    $ helm delete weblogic-kubernetes-operator -n opns

  5. Delete the label from the OAM namespace:

    $ kubectl label namespaces <domain_namespace> weblogic-operator-

    For example:

    $ kubectl label namespaces oamns weblogic-operator-

  6. Delete the service account for the operator:

    $ kubectl delete serviceaccount <sample-kubernetes-operator-sa> -n <domain_namespace>

    For example:

    $ kubectl delete serviceaccount op-sa -n opns

  7. Delete the operator namespace:

    $ kubectl delete namespace <sample-kubernetes-operator-ns>

    For example:

    $ kubectl delete namespace opns

  8. To delete NGINX:

    $ helm delete oam-nginx -n <domain_namespace>

    For example:

    $ helm delete oam-nginx -n oamns

    Then run:

    $ helm delete nginx-ingress -n <domain_namespace>

    For example:

    $ helm delete nginx-ingress -n oamns

  9. Delete the OAM namespace:

    $ kubectl delete namespace <domain_namespace>

    For example:

    $ kubectl delete namespace oamns
