+Feature: Distributed Locking
+****************************
+
+Summary
+^^^^^^^
+
+The Distributed Locking Feature provides locking of resources across a pool of PDP-D hosts. The list of locks is maintained in a database, where each record includes a resource identifier, an owner identifier, and an expiration time. Typically, a drools application will unlock the resource when it's operation completes. However, if it fails to do so, then the resource will be automatically released when the lock expires, thus preventing a resource from becoming permanently locked.

+****************
+Feature: Pooling
+****************
+
+Summary
+^^^^^^^
+
+The Pooling feature provides the ability to load-balance work across a “pool” of active-active Drools-PDP hosts. This particular implementation uses a DMaaP topic for communication between the hosts within the pool.
+
+The pool is adjusted automatically, with no manual intervention when:
+ * a new host is brought online
+ * a host goes offline, whether gracefully or due to a failure in the host or in the network
+
+Assumptions and Limitations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+ * Session persistence is not required
+ * Data may be lost when processing is moved from one host to another
+ * The entire pool may shut down if the inter-host DMaaP topic becomes inaccessible
+
+ .. image:: poolingDesign.png
+
+
+Key Points
+^^^^^^^^^^
+ * Requests are received on a common DMaaP topic
+ * DMaaP distributes the requests randomly to the hosts
+ * The request topic should have at least as many partitions as there are hosts
+ * Uses a single, internal DMaaP topic for all inter-host communication
+ * Allocates buckets to each host
+ * Requests are assigned to buckets based on their respective “request IDs”
+ * No session persistence
+ * No objects copied between hosts
+ * Requires feature(s): distributed-locking
+ * Precludes feature(s): session-persistence, active-standby, state-management
+
+Example Scenario
+^^^^^^^^^^^^^^^^
+ 1. Incoming DMaaP message is received on a topic — all hosts are listening, but only one random host receives the message
+ 2. Decode message to determine “request ID” key (message-specific operation)
+ 3. Hash request ID to determine the bucket number
+ 4. Look up host associated with hash bucket (most likely remote)
+ 5. Publish “forward” message to internal DMaaP topic, including remote host, bucket number, DMaaP topic information, and message body
+ 6. Remote host verifies ownership of bucket, and routes the DMaaP message to its own rule engine for processing
+
+ The figure below shows several different hosts in a pool. Each host as a copy of the bucket assignments, which specifies which buckets are assigned to which hosts. Incoming requests are mapped to a bucket, and a bucket is mapped to a host, to which the request is routed. The host table includes an entry for each active host in the pool, to which one or more buckets are mapped.
+
+ .. image:: poolingPdps.png
+
+Bucket Reassignment
+^^^^^^^^^^^^^^^^^^^
+ * When a host goes up or down, buckets are rebalanced
+ * Attempts to maintain an even distribution
+ * Leaves buckets with their current owner, where possible
+ * Takes a few buckets from each host to assign to new hosts
+
+ For example, in the diagram below, the left side shows how 32 buckets might be assigned among four different hosts. When the first host fails, the buckets from host 1 would be reassigned among the remaining hosts, similar to what is shown on the right side of the diagram. Any requests that were being processed by host 1 will be lost and must be restarted. However, the buckets that had already been assigned to the remaining hosts are unchanged, thus requests associated with those buckets are not impacted by the loss of host 1.
+
+ .. image:: poolingBuckets.png
+
+Usage
+^^^^^
+
+For pooling to be enabled, the distributed-locking feature must be also be enabled.

+Scalability, Resiliency and Manageability
+*****************************************
+
+.. contents::
+ :depth: 3
+
+The new Beijing release scalability, resiliency, and manageablity are described here. These capabilities apply to the OOM/Kubernetes installation.
+
+Installation
+^^^^^^^^^^^^
+Follow the OOM installation instructions at http://onap.readthedocs.io/en/latest/submodules/oom.git/docs/index.html
+
+Overview of the running system
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Upon initialization, you should see pools of 4 PDP-Ds and 2 PDP-Xs:
+
+.. code-block:: bash
+ :caption: verify pods
+
+ kubectl get pods --all-namespaces -o=wid

+ onap dev-policydb-587d55bdff-4f5dz 1/1 Running 0 18m 10.42.12.242 k8sx
+
+
+and a service for every component:
+
+.. code-block:: bash
+ :caption: verify services
+
+ kubectl get services --all-namespaces
+
+ onap brmsgw NodePort 10.43.209.173 <none> 9989:30216/TCP 24m
+ onap drools NodePort 10.43.27.92 <none> 6969:30217/TCP,9696:30221/TCP 24m
+ onap nexus NodePort 10.43.19.171 <none> 8081:30236/TCP 24m

+ onap pdp ClusterIP None <none> 8081/TCP 24m
+ onap policydb ClusterIP None <none> 3306/TCP 24m
+
+Config and Decision policy requests will be distributed across PDP-Xs through the *pdp* service. PDP-X clients (such as DCAE) should configure their URLs to go through the *pdp* service. Their requests will be distributed across the available PDP-X replicas. The PDP-Xs can be also accessed individually (dev-pdp-0 and dev-pdp-1 above), but is preferable to that external clients use the service.
+
+PDP-Ds are also accessible on a group fashion by using the service IP. Nevertheless, as DMaaP is the main means of communication with other ONAP components, the service interface is not used heavily.
+
+
+Healthchecks
+^^^^^^^^^^^^
+
+Verify that the policy healtcheck passes by the robot framework:
+
+.. code-block:: bash
+ :caption: ~/oom/kubernetes/robot/ete-k8s.sh onap health 2> /dev/null | grep PASS
+
+ Basic Policy Health Check | PASS |
+
+A policy healthcheck (with more detailed output) can be done directly to the drools service in the policy VM.
+
+.. code-block:: none
+ :caption: Healtcheck on the PDP-D service
+
+ curl --silent --user '<username>:<password> -X GET http://localhost:30217/healthcheck | python -m json.tool
+
+ {
+ "details": [
+ {
+ "code": 200,
+ "healthy": true,
+ "message": "alive",
+ "name": "PDP-D",
+ "url": "self"
+ },
+ {
+ "code": 200,
+ "healthy": true,
+ "message": "",
+ "name": "PAP",
+ "url": "http://pap:9091/pap/test"
+ },
+ {
+ "code": 200,
+ "healthy": true,
+ "message": "",
+ "name": "PDP",
+ "url": "http://pdp:8081/pdp/test"
+ }
+ ],
+ "healthy": true
+ }
+
+
+PDP-X active/active pool
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The policy engine UI (console container in the pap pod) can be used to check that the the 2 individual PDP-Xs are synchronized.
+The console URL is accessible at ``http://<oom-vm>:30219/onap/login.htm``. Select the PDP tab.
+
+ .. image:: srmPdpxPdpMgmt.png
+
+After initialization, there will be no policies loaded into the policy subsystem. You can verify it, by accessing the Editor tab in the UI.
+
+
+PDP-D Active/Active Pool
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The PDP-Ds replicas will come up with the amsterdam controller installed in brainless mode (no maven coordinates) since the controller has not been associated with a set of drools rules to run (control loop rules).
+
+The following command can be issued on each of the PDP-D replicas IPs:
+
+.. code-block:: bash
+ :caption: Querying the rules association for a PDP-D replica
+
+ curl --silent --user '<username>:<password>' -X GET http://<drools-replica-ip>:9696/policy/pdp/engine/controllers/amsterdam/drools | python -m json.tool
+
+ {
+ "alive": false,
+ "artifactId": "NO-ARTIFACT-ID",
+ "brained": false,
+ "canonicalSessionNames": [],
+ "container": null,
+ "groupId": "NO-GROUP-ID",
+ "locked": false,
+ "recentSinkEvents": [],
+ "recentSourceEvents": [],
+ "sessionNames": [],
+ "version": "NO-VERSION"
+ }
+
+Installing Policies
+^^^^^^^^^^^^^^^^^^^
+
+The OOM default installation will come with no policies pre-configured. There is a sample script used by integration teams to load policies to support all 4 use cases at: /tmp/policy-install/config/push-policies.sh in the pap container within the pap pod. This script can be modified for your own particular installation, for example if only interested in vCPE use cases, remove those vCPE related API REST calls. For the vFW use case, you may want to edit the encoded operational policy to point to the proper resourceID in your installation.
+
+The above mentioned push-policies.sh script can be executed as follows:
+
+.. code-block:: bash
+ :caption: Installing the default policies
+
+ kubectl exec -it dev-pap-8587696769-vwj6k -c pap -n onap -- bash -c "export PRELOAD_POLICIES=true; /tmp/policy-install/config/push-policies.sh"

+
+
+The policies pushed can be viewed through the Policy UI:
+
+ .. image:: srmEditor.png
+
+As a consequence of pushing the policies, the brmsgw component will compose drools rules artifacts and publish them to the nexus respository at ``http://<oom-vm>:30236/nexus/``
+
+ .. image:: srmNexus.png
+
+At the same time each replica of the PDP-Ds will receive notifications for each new version of the policies to run for the amsterdam controller. You can run the following command to see how the amsterdam controller is associated with the latest rules version. The following command can be used for verification for each replica:
+
+
+.. code-block:: none
+ :caption: Querying the rules association of a PDP-D replica
+
+ curl --silent --user '<username><password> -X GET http://<replica-ip>:9696/policy/pdp/engine/controllers/amsterdam/drools | python -m json.tool
+ {
+ "alive": true,
+ "artifactId": "policy-amsterdam-rules",

+ ],
+ "sessions": [
+ "closedloop-amsterdam"
+ ],
+ "version": "0.4.0"
+ }
+
+Likewise, for verification purposes, each PDP-X replica can be queried directly to retrieve policy information. The following commands can be used to query a policy through the pdp service:
+
+
+.. code-block:: bash

+PDP-X Resiliency
+^^^^^^^^^^^^^^^^
+
+A PDP-X container failure can be simulated by performing a"policy.sh stop" operation within the PDP-X container, this in fact will shutdown the PDP-X service. The kubernetes liveness operation will detect that the ports are down, inferring there's a problem with the service, and in turn, will restart the container. In the following example will cause PDP-X 1 to fail.
+
+.. code-block:: bash
+ :caption: Causing PDP-X 1 service to fail
+
+ ubuntu@k8sx:~$ kubectl exec -it dev-pdp-1 --container pdp -n onap -- bash -c "source /opt/app/policy/etc/profile.d/env.sh; policy.sh stop;"
+ pdplp: STOPPING ..
+ pdp: STOPPING ..
+
+Upon detection of the service being down through the liveness check, the container will be restarted. Note the restart count when querying the status of the pods:
+
+.. code-block:: bash
+ :caption: Checking PDP-X 1 restart count

+This screen will be updated to reflect PDP-X 1 is back alive, after PDP-X 1 synchronizes itself with the PAP.
