Post Install Configuration

Follow these post install configuration steps.

  1. Create a Server Overrides File
  2. Removing OAM Server from WebLogic Server 12c Default Coherence Cluster
  3. WebLogic Server Tuning
  4. Enable Virtualization
  5. Restart the domain

Create a Server Overrides File

  1. Navigate to the following directory:

    $ cd $WORKDIR/kubernetes/create-access-domain/domain-home-on-pv/output/weblogic-domains/accessdomain

  2. Create a setUserOverrides.sh with the following contents:

    DERBY_FLAG=false
JAVA_OPTIONS="${JAVA_OPTIONS} -Djava.net.preferIPv4Stack=true"
MEM_ARGS="-Xms8192m -Xmx8192m"

  3. Copy the setUserOverrides.sh file to the Administration Server pod:

    $ chmod 755 setUserOverrides.sh
$ kubectl cp setUserOverrides.sh oamns/accessdomain-adminserver:/u01/oracle/user_projects/domains/accessdomain/bin/setUserOverrides.sh

    Where oamns is the OAM namespace and accessdomain is the DOMAIN_NAME/UID.

  4. Stop the OAM domain using the following command:

    $ kubectl -n <domain_namespace> patch domains <domain_uid> --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "Never" }]'

    For example:

    $ kubectl -n oamns patch domains accessdomain --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "Never" }]'

    The output will look similar to the following:

    domain.weblogic.oracle/accessdomain patched

  5. Check that all the pods are stopped:

    $ kubectl get pods -n <domain_namespace>

    For example:

    $ kubectl get pods -n oamns

    The output will look similar to the following:

    NAME                                                     READY   STATUS        RESTARTS   AGE
accessdomain-adminserver                                 1/1     Terminating   0          27m
accessdomain-create-oam-infra-domain-job-7c9r9           0/1     Completed     0          4h29m
accessdomain-oam-policy-mgr1                             1/1     Terminating   0          24m
accessdomain-oam-server1                                 1/1     Terminating   0          24m
helper                                                   1/1     Running       0          4h44m
nginx-ingress-ingress-nginx-controller-76fb7678f-k8rhq   1/1     Running       0          108m

    The Administration Server pod and Managed Server pods will move to a STATUS of Terminating. After a few minutes, run the command again and the pods should have disappeared:

    NAME                                                     READY   STATUS      RESTARTS   AGE
accessdomain-create-oam-infra-domain-job-7c9r9           0/1     Completed   0          4h30m
helper                                                   1/1     Running     0          4h45m
nginx-ingress-ingress-nginx-controller-76fb7678f-k8rhq   1/1     Running     0          109m

  6. Start the domain using the following command:

    $ kubectl -n <domain_namespace> patch domains <domain_uid> --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "IfNeeded" }]'

    For example:

    $ kubectl -n oamns patch domains accessdomain --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "IfNeeded" }]'

    Run the following kubectl command to view the pods:

    $ kubectl get pods -n <domain_namespace>

    For example:

    $ kubectl get pods -n oamns

    The output will look similar to the following:

    NAME                                                     READY   STATUS      RESTARTS   AGE
accessdomain-create-oam-infra-domain-job-7c9r9           0/1     Completed   0          4h30m
accessdomain-introspector-mckp2                          1/1     Running     0          8s
helper                                                   1/1     Running     0          4h46m
nginx-ingress-ingress-nginx-controller-76fb7678f-k8rhq   1/1     Running     0          110m

    The Administration Server pod will start followed by the OAM Managed Servers pods. This process will take several minutes, so keep executing the command until all the pods are running with READY status 1/1:

    NAME                                                     READY   STATUS      RESTARTS   AGE  
accessdomain-adminserver                                 1/1     Running     0          5m38s
accessdomain-create-oam-infra-domain-job-7c9r9           0/1     Completed   0          4h37m
accessdomain-oam-policy-mgr1                             1/1     Running     0          2m51s
accessdomain-oam-server1                                 1/1     Running     0          2m50s
helper                                                   1/1     Running     0          4h52m
nginx-ingress-ingress-nginx-controller-76fb7678f-k8rhq   1/1     Running     0          116m

Removing OAM Server from WebLogic Server 12c Default Coherence Cluster

Exclude all Oracle Access Management (OAM) clusters (including Policy Manager and OAM runtime server) from the default WebLogic Server 12c coherence cluster by using the WebLogic Server Administration Console.

From 12.2.1.3.0 onwards, OAM server-side session management uses the database and does not require coherence cluster to be established. In some environments, warnings and errors are observed due to default coherence cluster initialized by WebLogic. To avoid or fix these errors, exclude all of the OAM clusters from default WebLogic Server coherence cluster using the following steps:

  1. Login to the WebLogic Server Console at https://${MASTERNODE-HOSTNAME}:${MASTERNODE-PORT}/console.
  2. Click Lock & Edit.
  3. In Domain Structure, expand Environment and select Coherence Clusters.
  4. Click defaultCoherenceCluster and select the Members tab.
  5. From Servers and Clusters, deselect all OAM clusters (oam_cluster and policy_cluster).
  6. Click Save.
  7. Click Activate changes.

WebLogic Server Tuning

For production environments, the following WebLogic Server tuning parameters must be set:

Add Minimum Thread constraint to worker manager “OAPOverRestWM”

  1. Login to the WebLogic Server Console at https://${MASTERNODE-HOSTNAME}:${MASTERNODE-PORT}/console.
  2. Click Lock & Edit.
  3. In Domain Structure, click Deployments.
  4. On the Deployments page click Next until you see oam_server.
  5. Expand oam_server by clicking on the + icon, then click /iam/access/binding.
  6. Click the Configuration tab, followed by the Workload tab.
  7. Click wm/OAPOverRestWM
  8. Under Application Scoped Work Managed Components, click New.
  9. In Create a New Work Manager Component, select Minumum Threads Constraint and click Next.
  10. In Minimum Threads Constraint Properties enter the Count as 400 and click Finish.
  11. In the Save Deployment Plan change the Path to the value /u01/oracle/user_projects/domains/accessdomain/Plan.xml, where accessdomain is your domain_UID.
  12. Click OK and then Activate Changes.

Remove Max Thread Constraint and Capacity Constraint

  1. Repeat steps 1-7 above.
  2. Under Application Scoped Work Managed Components select the check box for Capacity and MaxThreadsCount. Click Delete.
  3. In the Delete Work Manage Components screen, click OK to delete.
  4. Click on Release Configuration and then Log Out.

oamDS DataSource Tuning

  1. Login to the WebLogic Server Console at https://${MASTERNODE-HOSTNAME}:${MASTERNODE-PORT}/console.
  2. Click Lock & Edit.
  3. In Domain Structure, Expand Services and click Data Sources.
  4. Click on oamDS.
  5. In Settings for oamDS, select the Configuration tab, and then the Connection Pool tab.
  6. Change Initial Capacity, Maximum Capacity, and Minimum Capacity to 800 and click Save.
  7. Click Activate Changes.

Enable Virtualization

  1. Log in to Oracle Enterprise Manager Fusion Middleware Control at https://${MASTERNODE-HOSTNAME}:${MASTERNODE-PORT}/em
  2. Click WebLogic Domain > Security > Security Provider Configuration.
  3. Expand Security Store Provider.
  4. Expand Identity Store Provider.
  5. Click Configure.
  6. Add a custom property.
  7. Select virtualize property with value true and click OK.
  8. Click OK again to persist the change.

Restart the domain

For the above changes to take effect, you must restart the OAM domain:

  1. Stop the OAM domain using the following command:

    $ kubectl -n <domain_namespace> patch domains <domain_uid> --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "Never" }]'

    For example:

    $ kubectl -n oamns patch domains accessdomain --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "Never" }]'

    The output will look similar to the following:

    domain.weblogic.oracle/accessdomain patched

  2. Check that all the pods are stopped:

    $ kubectl get pods -n <domain_namespace>

    For example:

    $ kubectl get pods -n oamns

    The output will look similar to the following:

    NAME                                                     READY   STATUS        RESTARTS   AGE

nginx-ingress-ingress-nginx-controller-76fb7678f-k8rhq   1/1     Running     0          109m

  3. Start the domain using the following command:

    $ kubectl -n <domain_namespace> patch domains <domain_uid> --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "IfNeeded" }]'

    For example:

    $ kubectl -n oamns patch domains accessdomain --type='json' -p='[{"op": "replace", "path": "/spec/serverStartPolicy", "value": "IfNeeded" }]'

    Run the following kubectl command to view the pods:

    $ kubectl get pods -n <domain_namespace>

    For example:

    $ kubectl get pods -n oamns

    The output will look similar to the following:

    NAME                                                     READY   STATUS      RESTARTS   AGE
