  • Upgrade from any version V4.1.0.0 through V4.1.7.4.0
    StepTaskNotes
    1

    If you are upgrading from V4.1.5.x and you used Policy Recommendations for the first time in V4.1.5.x, after you upgrade your database, use the State Management option in the Revert to Baseline feature to apply the correct State Configuration for the Policy Recommendation Family.

    When you do so, you will need to provide mappings from the incorrect states to the corresponding correct states, as shown in the following table:

    Custom (incorrect)

    Baseline (correct)

    Accepted by ASM

    Completed

    Closed

    Completed

    Consolidated

    Superseded

    Open

    Proposed

    Pending

    Pending Approval

    Superseded

    Superseded

    This step is necessary because an incorrect baseline State Configuration was delivered for the Policy Recommendation family in V4.1.5.0. The baseline configuration was corrected in V4.1.6.0.

    The correct baseline state configuration must be applied for various queries and lists in GE Digital APM to function as expected.

    You do not need to complete this step if:

    • You never used V4.1.5.x

      -or-

    • You never used Policy Recommendations

About the Asset Health Services

When you deploy the Asset Health Manager, Process Data Integration, and Policy Designer modules together, the services used by each module interact with each other in various ways. This topic summarizes those services and describes a standard system architecture containing the components used by all three modules.

Services Summary

The following services are used by the Asset Health Manager, Process Data Integration, and Policy Designer modules:

  • Asset Health Indicator Service: Automatically updates the following field values in a Health Indicator record when reading values related to the health indicator source record (for example, an OPC Tag or Measurement Location record) change:
    • Alert Level
    • Last Reading Date
    • Last Char Reading Value (for records that accept character values)
    • Last Numeric Reading Value (for records that accept numeric values)

    This service also facilitates the automatic creation of Health Indicator records for configured sources.

  • Policy Trigger Service: When an input to a policy (that is, an associated record in the GE Digital APM database or reading value in the process historian) changes or when a policy schedule is due, a message is added to the policy trigger queue. The Policy Trigger Service monitors the trigger queue. When it receives a message, it determines which policy instances should be executed for the message, and then it sends corresponding messages to an appropriate policy execution queue.
  • Policy Execution Service: The Meridium Policy Execution Service handles the execution of policies. Specifically, the Policy Execution Service monitors a corresponding policy execution queue and executes the policy instances that are added to it.
  • Process Data Integration (PDI) Service: Monitors the subscribed tags (that is, tags that are used in policies and health indicators or tags for which readings are being stored in the GE Digital APM database) and, when data changes occur on these tags, adds messages to the appropriate queues. This service also facilitates the automatic import and synchronization of tags from a configured process historian. For more information, refer to the PDI Services section of the documentation.

Standard System Architecture Configuration

The following diagram illustrates the machines in the GE Digital APM system architecture when the Policy Designer, Process Data Integration (PDI), and Asset Health Manager (AHM) modules are used together. This image depicts the standard configuration, where the OPC Server software and the Process Data Integration Service are on the same machine.

Note: In this example configuration, only one machine of each type is illustrated. Your specific architecture may include multiple GE Digital APM Servers, multiple OPC Servers, or multiple GE Digital APM Servers used for policy executions.

The following table summarizes the machines illustrated in this diagram and the software and services that you will install when you complete the first-time deployment steps for Asset Health Manager, Process Data Integration, and Policy Designer.

About Configuring Policy Execution

Policy designers can configure a policy to be executed on a schedule or automatically when records or reading values associated with the policy are updated. This topic describes the ways that the items configured in the first-time deployment workflow facilitate each type of policy execution.

Note: Only the active instances of active policies are executed.

Automatic Execution

When records or reading values associated with the policy are updated, the GE Digital APM Server adds messages to the policy trigger queue. The Policy Trigger Service monitors the trigger queue. When it receives a message, it determines which policy instances should be executed for the message, and then it sends corresponding messages to an appropriate policy execution queue. Finally, the corresponding Policy Execution Service executes the policies associated with the records or reading values that were updated.

Scheduled Execution

When a policy is due, the scheduled job adds a message to the policy trigger queue. The Policy Trigger Service monitors the trigger queue and sends messages to the appropriate policy execution queue. Finally, the corresponding Policy Execution Service executes the policies that are due.

Configure Impersonation User for Policy Execution Service

About This Task

The Policy Execution Service runs under the impersonation of a Super User. By default, the service impersonates the MIADMIN user account. However, you can configure the user account that the Policy Execution Service must impersonate.
Important: The user that you configure for impersonation must be a Super User and must not be locked out of any data source. Any modifications to the security privileges of the configured user account may lead to failure of the Policy Execution Service.

Procedure

  1. On the GE Digital APM Server, access the folder that contains the Policy Execution Service files.
    Note: If you installed GE Digital APM in the default location, you can locate this folder in the following directory:

    C:\Program Files\Meridium\Services

  2. Access the Meridium.Policies.ExecutionService.exe.config file in an application that can be used to modify XML files (for example, Notepad++).
  3. Within the <appSettings> tags, locate the following text:
    <add key="ImpersonationUser" value=�?MIADMIN�? />
  4. Replace MIADMIN with the user account that you want the Policy Execution Service to impersonate.
  5. Locate the following text:
    <add key="MinImpersonationLoginDelay" value=�?60000�? />
  6. Replace 60000 with the interval value in milliseconds at which the Policy Execution Service must attempt to log in to a data source.
    If the Policy Execution Service fails to log in to a data source using the impersonated user account, the service attempts to log in to the data source at intervals that you specified, and processes the execution requests from the other data sources between the successive login attempts.
  7. Save and close the file.
    The updated settings will be applied when the Policy Execution Service is restarted.

Delete Duplicate Policies from the GE Digital APM Database

About This Task

The GE Digital APM database may contain duplicate records of a family policy configured for the same family and trigger. You may face issues while working with the family policies because of such duplicate records. While upgrading GE Digital APM to the latest version, you must identify and delete the duplicate records that exist for the same family and trigger.

Procedure

  1. Run the following query on your database to identify the duplicate family policy records that exist for the same family and trigger:
    SELECT MI_FAMPOLICY_FMLY_ID_CHR,MI_FAMPOLICY_TRIGGER_C, count(*)
FROM MI_FAMPOLICY
GROUP BY MI_FAMPOLICY_FMLY_ID_CHR,MI_FAMPOLICY_TRIGGER_C
HAVING COUNT(*) > 1;
  2. Identify the correct records that must be retained in the database, and then delete the unwanted duplicate records.

Configure the Policy Trigger Service

Procedure

  1. On the GE Digital APM Server, navigate to the folder where the Policy Trigger Service files are installed. If you installed the software in the default location, you can locate this file in the folder C:\Program Files\Meridium\Services.
  2. Open the file Meridium.Policies.Service.exe.config in an application that you can use to modify XML (for example, Notepad).
  3. Within the <executionServers> tags, locate the following text: <add url="http://localhost/Meridium" />
  4. Within the add url attribute, choose one of the following:
    • If you have only one GE Digital APM Server in your system architecture, accept the default value (that is, localhost).
    • If you have more than one GE Digital APM Server in your system architecture, replace localhost with the name of the server cluster that you want to use for policy executions.
  5. Save and close the file.
    Your settings will be applied when the Policy Trigger Service is started or restarted.

Configure Multiple GE Digital APM Servers for Policy Execution

Depending on the number of policies that you need to manage in your system, you may have multiple GE Digital APM Servers to process policy executions. Based on your company’s preference for server load balancing, you can configure your GE Digital APM System Architecture using global load balancing or isolated load balancing.

Regardless of the approach you use, you must fully configure each GE Digital APM Server according to the steps for deploying the basic GE Digital APM system architecture. In addition, each GE Digital APM Server must be configured to use the same instance of Redis.

Global Load Balancing

In global load balancing, you configure all GE Digital APM Server(s) to process policy executions in a single load-balanced cluster. In this scenario, an increase in activity from any server can be absorbed across all servers in your system architecture. Because there is only one cluster to manage in this scenario, this is the simpler configuration to set up and manage.

In this scenario, you must:

Isolated Load Balancing

In isolated load balancing, you configure designated GE Digital APM Server(s) to process policy executions in a separate load-balanced cluster from other GE Digital APM Server(s). In this scenario, the policy execution processes are isolated from the GE Digital APM Server processes, therefore preventing an increase in activity in one cluster from negatively impacting the processes of the other.

In this scenario, you must:

  • Configure the Policy Trigger service on all GE Digital APM Servers to specify the name of the cluster used for policy executions.

  • Start the Policy Execution Service on only the GE Digital APM Servers in the cluster designated to process policy executions.

Configure the Meridium Notification Service for Policy Designer

About This Task

For the Policy Designer to work correctly, you must configure the Meridium Notification Service by modifying the file Meridium.Service.Notification.exe.config on all GE Digital APM Servers.

Procedure

  1. On the GE Digital APM Server, navigate to the folder where the Meridium Notification Service files are installed. If you installed the software in the default location, you can locate these files in the folder C:\Program Files\Meridium\Services.
  2. Open the file Meridium.Service.Notification.exe.config in an application that you can use to modify XML script (for example, Notepad).
  3. If you have not done so already, complete any necessary basic configuration for the Meridium Notification Service.
  4. Within the <notification> tags, within the <notificationSettings> tags, uncomment the following text string (that is, delete the <!-- and -->): <!-- <add key="policyExecutionService" serverType="external" endPointName="policyExecutionService" /> -->
  5. Within the <system.serviceModel> tags, within the <client> tags, uncomment the following text string (i.e., delete the <!-- and -->): <!-- <endpoint name="policyExecutionService" address="net.tcp://localhost/Meridium/PolicyExe/NotifyHandler" binding="netTcpBinding" contract="Meridium.Core.Common.Contracts.INotificationService" /> -->
  6. Save and close the file.
  7. Start or restart the Meridium Notification Service.
