Deployment

Deploy Policy Designer

The checklists in this section of the documentation contain all the steps necessary for deploying and configuring this module whether you are deploying the module for the first time or upgrading from a previous module.

Deploy Policy Designer for the First Time

Before You Begin

The following table outlines the steps that you must complete to deploy and configure this module for the first time. These instructions assume that you have completed the steps for deploying the basic system architecture.

These tasks may be completed by multiple people in your organization. GE Digital recommends, however, that the tasks be completed in the order in which they are listed.

Important: The Policy Execution Service uses the MIJOB user account. MIJOB should be a Super User, should have its time zone set to UTC, and must not be locked out of any data source configured on the GE Digital server. Any modifications to the security privileges of the MIJOB user account may lead to failure of the Policy Execution Service.

If you are deploying this module in APM Now, before you begin completing these tasks, review the system requirements for this module to identify the supported features for this module in APM Now. Unless noted, all deployment tasks in the following table are applicable for the deployment of this module in APM Now.

    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    Superseded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    Superseded

    Superseded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

      -or-

When you deploy the Asset Health Manager, OT Connect, 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, OT Connect, 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 OT Source 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, when a policy schedule is due, or a user submits an Execute Now request, 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 the policy execution queue. Even if your GE Digital APM system is configured with multiple Policy Execution servers, only one policy execution queue is used.
  • Policy Execution Service: The Policy Execution Service handles the execution of policies. Specifically, the Policy Execution Service monitors the policy execution queue and executes the policy instances that are added to it. If the GE Digital APM system is configured with multiple Policy Execution servers, when each Policy Execution Service completes the execution of a policy instance, it will execute the next instance from the shared policy execution queue. In this way, the policy execution load is automatically balanced across all available Policy Execution Services.
  • OT Connect Service: Monitors the subscribed tags (that is, tags that are used in policies and health indicators) 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 OT Source. For more information, refer to the OT Connect 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, OT Connect, and Asset Health Manager (AHM) modules are used together. This image depicts the standard configuration, where the OPC Server software and the OT Connect Adapter 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, OT Connect, and Policy Designer.

About 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. Policies may also be executed on demand. 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 any record or reading value is updated by the GE Digital APM Server, or when a reading value for a tag associated with one or more policies is updated on the process historian, 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, if any. Only active policy instances associated with the record or reading update will be executed. The Policy Trigger Service then sends corresponding messages to the policy execution queue for each relevant policy instance. Finally, a Policy Execution Service executes each policy instance that was added to the policy execution queue in turn.

Scheduled Execution

When a scheduled policy is due, a scheduled job adds a message to the policy trigger queue. The Policy Trigger Service monitors the trigger queue and sends messages to the policy execution queue for each active instance of the policy. Finally, a Policy Execution Service executes each active instance that was added to the policy execution queue in turn.

On Demand Execution

When you request a policy or policy instance execution from the Policy Designer user interface, or select a hyperlink configured to execute a policy or policy instance, a message is added to the policy trigger queue. The Policy Trigger Service monitors the trigger queue and sends messages to the policy execution queue for each active instance of the policy. Finally, a Policy Execution Service executes each active instance that was added to the policy execution queue in turn.

Configure Queue Settings for Policy Execution Service

About This Task

The Policy Execution Service on each GE Digital APM Server is configured to use a single shared ActiveMQ queue service. Available queue configuration options include retries, redelivery attempts and interval, and concurrency limit.

Procedure

    "redeliveryMinInterval": 1,
    "redeliveryMaxInterval": 2440,
    "redeliveryDelta": 5
  }
  4. Update the key values as desired.
  5. Save and close the file.
    The updated settings will be applied when the Meridium Policy Trigger service is stopped and restarted.

Configure the Time Limit for Policy Execution

About This Task

The Policy Execution Service limits the amount of time allocated to execute each policy instance. This ensures that the Policy Execution Service queue is not backlogged when a poorly designed policy takes too long to execute. If a policy execution is canceled as a result of the time limit, an error message appears in the policy execution history indicating that the time limit was exceeded. By default, the policy execution time limit is set to 15 minutes per policy instance. The minimum time limit is 1 minute, and the maximum time limit is 1 hour. This topic describes how to modify the Policy Execution Service configuration to change the time limit for policy execution.

Procedure

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

    C:\Program Files\Meridium\ApplicationServer\policy-execution

  2. Access the appsettings.json file in an application that can be used to modify JSON files (for example, Notepad++).
  3. In the file, locate the following text:
    "PolicyExecutionTimeoutMs": 900000
  4. Replace 900000 with the time limit value in milliseconds, that you want to apply to policy executions.
    Note: The value you enter should be between the minimum time limit of 60000 milliseconds (that is, 1 minute) and the maximum time limit of 3600000 milliseconds (that is, 1 hour).
  5. Save and close the file.
    The modified settings are applied when the Policy Execution Service is restarted. If the execution time of a policy instance exceeds the time limit that you have specified, the execution is canceled, and an error message is added to the policy execution history.
  6. On the GE Digital APM Server, access the folder that contains the Meridium configuration files.
    Note: If you have installed GE Digital APM in the default location, you can locate the folder in the following directory:

    C:\Program Files\Meridium

  7. Go to C:\Program Files\Meridium\ApplicationServer\api.
  8. Access the appsettings file in an application that can be used to modify JSON files (for example, Notepad++).
  9. Repeat steps 3 through 5.
    The modified settings are applied when Meridium Policy Execution service is stopped and restarted on each policy execution server and IIS is reset on the GE Digital APM Server.

Configure Execution Time Out Value for Math Node

About This Task

If the execution of a Math node in a policy takes a very long time, the execution times out after a pre-defined duration. By default, the execution times out after 1 minute. However, you can configure the interval after which the execution must time out for the Math node.

Procedure

  1. On the Policy Execution Server, go to C:\Program Files\Meridium\ApplicationServer\policy-execution.
  2. Access the appsettings.json file in an application that can be used to modify JSON files (for example, Notepad++).

    "MathNodeExecutionTimeout": 60000
  4. Replace 60000 with the interval value in milliseconds at which the execution of the Math node must time out.
  5. Save and close the file.
  6. On the GE Digital APM Server, go to C:\Program Files\Meridium\ApplicationServer\api.
  7. Access the appsettings file in an application that can be used to modify JSON files (for example, Notepad++).
  8. Repeat steps 3 through 5.
    The updated settings will be applied when the Policy Execution Service is stopped and restarted on the Policy Execution Server and IIS is reset on the GE Digital APM Server.

Configure the Default Historical Readings Time Range for the OT Connect Tag node

About This Task

During policy execution, if a specific time range to retrieve the historical data for the OT Connect Tag node cannot be determined. For example, if there is no collection filter applied to the Historical Readings output from the node, by default, two years of data will be added. However, you can change the default time range by modifying the settings on the Policy Execution Server and GE Digital APM Server.

Procedure

  1. On the Policy Execution Server, go to C:\Program Files\Meridium\ApplicationServer\policy-execution.
  2. Access the appsettings.json file in an application that can be used to modify JSON files (for example; Notepad++).

Delete Duplicate Policies from the GE Digital APM Database

About This Task

If you are upgrading from any version V4.0.0.0.0 through 4.3.0.7.0, 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 any 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 Alternative Query for the Policy Designer Overview Page

  9. In the same row, select .
    The Catalog Item Properties window appears, displaying the properties of the alternative query.
  10. In the Name box, delete the existing value, and then enter Policy Overview – Policies.
  11. Select Done.
    The alternative query is configured for the Policy Designer Overview page.

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 preference for server load balancing, you can configure these servers 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 and ActiveMQ.

Global Load Balancing

In global load balancing, you configure all GE Digital APM Servers to process policy executions in a single load-balanced cluster. In this scenario, an increase in policy execution demand can be absorbed across all servers in your system architecture.

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 this scenario, the policy execution processes are isolated from other GE Digital APM Server processes, therefore preventing an increase in policy execution activity from negatively impacting other processes.

In this scenario, you must:

  • Configure and start the Policy Trigger service on at least one GE Digital APM Server.

  • Configure and start the Policy Execution Service on only the GE Digital APM Servers that you want to use to process policy executions.
