Alert Notifications: Mastering Workflows in BMC Helix ITSM

In the complex landscape of IT Service Management (ITSM), timely and accurate communication is paramount. Whether it’s notifying a support agent about a critical incident, alerting a manager to a pending SLA breach, or informing an end-user about a service update, effective alert notifications are the lifeblood of efficient operations. At the heart of these notifications within BMC Helix ITSM (and its predecessor, BMC Remedy Action Request System) lie powerful automation tools known as Workflows.

Workflows are more than just scripts; they are meticulously designed sets of processes that automate business operations. They leverage a combination of active links, filters, and escalations to trigger specific actions based on predefined conditions and execution options. Understanding how these components interact is crucial for anyone involved in customizing, managing, or troubleshooting an ITSM environment.

The Building Blocks: Understanding Workflow Objects

At their core, workflows in BMC Helix ITSM are built upon three primary object types. Each plays a distinct role in how and when actions are executed:

1. Active Links

Think of Active Links as the user-facing or client-side orchestrators. They are designed to react to user interactions or the information currently displayed on a screen. When a user clicks a button, navigates to a new form, or performs an action within the BMC Helix ITSM interface, an Active Link can spring into action.

• When they trigger: Client operations (user actions) or information on the current screen.
• What they do: They can perform a wide array of tasks directly impacting the user experience or data manipulation. This includes displaying informative messages, dynamically changing the appearance of fields (like highlighting a critical field in red), or facilitating data transfer between different forms by pushing, inserting, or fetching records.

Real-world Example: Imagine a Service Desk agent is updating a ticket. An Active Link could be configured to automatically populate the ‘Resolution’ field with a predefined template if the ‘Status’ field is changed to ‘Resolved’. Another example: clicking a custom button on an Incident form might trigger an Active Link to open a new window displaying related knowledge articles.

2. Filters

Filters operate on the server side, acting as gatekeepers and processors during data transactions. They scrutinize changes being made to records or forms before they are permanently committed to the database. Filters are essential for enforcing business rules, data integrity, and triggering server-side processes.

• When they trigger: Server-side processing of form transactions. This typically happens when a record is submitted, modified, or deleted.
• What they do: They analyze the data in transit. Based on specific conditions, filters can validate data, update related records, generate notifications, or initiate other server-side processes.

Real-world Example: When a new Incident is submitted, a Filter might check if the ‘Urgency’ and ‘Impact’ fields have been populated. If not, it could trigger a message back to the user (via an Active Link) to provide this information before allowing the submission. Another common use is to automatically assign an Incident to a specific support group based on the selected ‘Categorization’ fields.

3. Escalations

Escalations are the time-based workhorses of BMC Helix ITSM workflows. While Active Links and Filters react to immediate events, Escalations proactively scan the database at predetermined intervals to identify and act upon records that meet specific criteria over time.

• When they trigger: Regularly scheduled checks against records in the database.
• What they do: Similar to Filters, they can execute actions based on conditions met by records. However, their power lies in their ability to address situations that might otherwise go unnoticed if they solely relied on user interaction or immediate transaction.

Real-world Example: An Escalation can be set up to monitor Incidents. If an Incident’s ‘Status’ remains ‘In Progress’ for more than 48 hours without any activity (e.g., no notes added or field changes), the Escalation could trigger a notification to the assigned support group manager, or automatically increase the priority of the ticket to ensure it gets addressed.

The Mechanics: Workflow Actions

Each workflow object (Active Link, Filter, Escalation) can be empowered with a variety of actions to perform specific tasks. The table below provides a comprehensive overview of common workflow actions and their availability across these object types:

Common Workflow Actions

Actions Exclusive to Specific Workflow Types

• Only in Active Links (AL): DDE, Open Window, Run Macro, Commit Changes, OLE Automation, Wait.
• In Filters (FLR) & Escalations (ESCL) but not in AL: None explicitly listed in the provided reference, indicating a strong server-side focus for these combinations.
• In FLR but not in ESCL: None explicitly listed in the provided reference.
• Common to AL, FLR & ESCL: Distributed Server Option, Direct SQL, Push Fields, Run Process, Service. These are versatile actions that can be employed across different operational contexts.
• In AL & FLR but not ESCL: Call Guide, Exit Guide, Go to Guide Label, Goto, Message, Notify. These actions are primarily for client-side interaction and guiding user workflows, or for immediate user feedback.
• In FLR & ESCL but not AL: None explicitly listed in the provided reference.

Understanding Filter Execution Options

Filters have a crucial set of execution options that dictate precisely when they will be invoked during a transaction. This granular control is vital for ensuring that business logic is applied at the correct stage of a data lifecycle:

• Submit: This is arguably the most common execution option. The filter runs when a new record is submitted to the server. This is the perfect place to enforce initial data validation or set default values. Example: When a new Incident is submitted, a filter might automatically set the ‘Status’ to ‘New’ and assign a default support group.
• Modify: The filter executes when an existing record is modified. This is ideal for actions that depend on changes to specific fields. Example: If the ‘Assigned Group’ on an Incident is changed, a filter could send a notification to the new assignee.
• Delete: The filter runs when a record is deleted. This is useful for auditing or cleanup operations. Example: Before a record is permanently deleted, a filter could log the deletion event or prompt for a confirmation.
• Get Entry: This option triggers the filter when a record is retrieved or searched for. This is less common for direct user-facing actions but can be used for logging or populating related information that isn’t directly displayed on the primary form.
• Merge: This option is triggered when a record is merged into the database, often through bulk import processes like BMC Remedy Data Import. It allows for post-import processing or validation. Example: After a bulk import of assets, a filter could run to update their status or assign them to specific owners based on imported data.
• Service: This option is a bit more nuanced. It’s typically triggered by a specific “Service” action within an Active Link. This allows an Active Link to pass data to a Filter for server-side processing without directly modifying the database itself. The Filter can then perform complex calculations or data manipulations and potentially update the database or trigger other actions.

Deep Dive into Specific Actions

Let’s explore some of the more specialized workflow actions in detail:

1. Direct SQL Action

This powerful action allows you to execute raw SQL commands directly against non-AR System databases. While immensely useful for integrating with external systems or performing complex data operations, it must be wielded with extreme caution.

• Availability: Active Links, Filters, Escalations.
• Use Case: Imagine you need to update a custom configuration table in an external database whenever a specific event occurs in BMC Helix ITSM. Direct SQL is your go-to.
• Caution: Incorrect SQL syntax or logic can lead to data corruption in either your external database or, more critically, in the AR System database itself. Always test thoroughly in a non-production environment and ensure you have robust error handling.

Official Documentation Reference: For detailed guidance on SQL integrations and best practices, consult the BMC documentation for BMC Helix ITSM or BMC Remedy Action Request System.

2. Push Fields Action

This is one of the most frequently used actions for automating data management. Push Fields allows you to copy values from fields in the current request to corresponding fields in another request, which can be on the same form or a different form.

• Availability: Active Links, Filters, Escalations.
• Use Case: When a Change Request is approved, a Push Fields action in a Filter can copy key details (like the Change Request ID, summary, and planned start/end dates) to the associated Incident record, ensuring all related tickets have up-to-date information. It can also be used to create new records in another form.
• Modes: Push Fields can be configured to update existing records or create new ones.

3. Set Fields Action

Similar to Push Fields but simpler, Set Fields allows you to set the value of a field directly within the current record or a target record based on a specified value, calculation, or another field’s value.

• Availability: Active Links, Filters, Escalations.
• Use Case: If an Incident’s ‘Impact’ is set to ‘High’, a Set Fields action in a Filter could automatically set the ‘Urgency’ to ‘High’ as well, enforcing a business rule.

4. Notify Action

The Notify action is the direct mechanism for sending alert notifications to users or groups. It’s the culmination of many workflow processes.

• Availability: Active Links, Filters.
• Use Case: When an Incident is assigned to a new group, a Filter can use the Notify action to send an email or a system notification to the members of that group, informing them of the new assignment. The content of the notification can be dynamically populated using field values.

5. Run Process Action

This action allows you to execute external programs or scripts on the client or server. It’s a gateway to more complex automation scenarios.

• Availability: Active Links, Filters, Escalations.
• Use Case: You might use Run Process to trigger a custom script that performs advanced data validation, calls an external API for information enrichment, or initiates a system backup. The distinction between “Commit Changes” and “Run Process PERFORM-ACTION-APPLY” is important here: “Commit Changes” is typically logged, whereas “Run Process PERFORM-ACTION-APPLY” offers more flexibility for dynamic workflow generation and its logging behavior is less explicit regarding the action type itself. For dynamic workflows, “Run Process” is often preferred.

6. Commit Changes Action

This action is crucial for managing how data is saved. Its behavior depends on its context:

• With a dialog box: It captures data entered in a dialog box and pushes it to fields on the parent form but does not save it to the database. This is useful for temporary data collection or staging.
• With a regular form: It applies the changes made to the form and performs the major form action (Submit, Search, Modify), effectively saving the data to the database.

Cache Modes: A Performance Consideration

The way BMC Helix ITSM manages its data cache can significantly impact the performance of your workflows, especially Escalations, which run at scheduled intervals. Understanding the two cache modes is essential for optimizing performance:

• Production Cache Mode: In this mode, application user operations are not delayed by administrative tasks. The server creates a separate, administrative copy of its cache. This is the default and generally preferred mode for production environments as it ensures a smoother user experience.
• Development Cache Mode: Here, administrative operations (like workflow changes, escalations, or server configuration updates) can lock out other users from the shared cache. The system waits for these administrative tasks to complete before allowing other operations. This mode can lead to significant delays, particularly for long-running tasks like complex escalations that might need to access and modify cache data frequently. It’s more suited for development and testing environments.

Impact on Escalations: If an Escalation needs to process a large number of records or perform resource-intensive operations, running it in Development Cache Mode can cause noticeable slowdowns for all users.

The `arsignal` Utility: Forcing a Refresh

Sometimes, after making changes to workflows, configurations, or user information, you need to ensure that the AR System server reloads this information. The `arsignal` utility is a command-line tool that allows you to send signals to the AR System server to force these reloads. This is especially useful when you suspect that the server is still operating with outdated cached information.

Here are some common `arsignal` flags relevant to workflows and alerts:

• -e: Recaches and reloads escalation definitions. Essential after modifying or creating escalations.
• -r: Recaches definitions from the database. A more general reload that can encompass various definitions.
• -c: Reloads information from the configuration file.
• -u: Reloads user information.
• -g: Reloads group and data dictionary information.

Example: After deploying new escalation rules, you would typically run the `arsignal` command with the `-e` flag to ensure the server picks up these changes immediately. For instance, on a Linux server, it might look like: `/opt/bmc/arsystem/bin/arsignal -e`.
