ARERR Messages: Understanding and Troubleshooting Common Errors in BMC Remedy and Helix
If you’ve spent any time working with BMC Remedy or its successor, BMC Helix ITSM, you’ve undoubtedly encountered them: ARERR messages. These cryptic alphanumeric codes are the silent (or sometimes not-so-silent) communicators of issues within the AR System (Action Request System) engine that powers these solutions. For IT professionals, especially those involved in administration, development, or support, understanding ARERR messages is not just helpful; it’s essential for keeping your systems running smoothly.
Think of ARERR messages as the system’s way of saying, “Something’s not quite right here, and here’s a hint about what it is.” They can range from minor annoyances that are easily fixable to critical errors that can bring operations to a halt. This article aims to demystify these messages, providing practical explanations, real-world examples, and actionable troubleshooting steps. We’ll also touch upon their relevance in interviews for IT roles.
What Exactly Are ARERR Messages?
ARERR messages, short for Action Request System Error messages, are generated by the BMC AR System server when it encounters a problem during its processing of user requests, workflow execution, data operations, or internal system functions. These errors are typically logged in the AR System server’s API logs, SQL logs, and the general AR System logs. Each message follows a specific format, usually:
ARERR [] : numberDescription of the error
- ARERR: The prefix indicating an Action Request System error.
- [
]: A unique numerical identifier for the specific error condition. This number is crucial for pinpointing the exact problem.number - Description: A brief, human-readable explanation of what went wrong.
These messages are invaluable for diagnosing problems because they provide a starting point for investigation. Without them, troubleshooting would be like searching for a needle in a haystack.
Why Are ARERR Messages Important?
The importance of ARERR messages cannot be overstated for several reasons:
- System Stability: Identifying and resolving ARERR messages prevents system failures, data corruption, and service disruptions.
- Troubleshooting Efficiency: They provide direct clues to the root cause of issues, significantly reducing the time and effort required for diagnosis.
- Performance Optimization: Some ARERR messages can indicate performance bottlenecks, allowing administrators to tune the system for better efficiency.
- User Experience: By resolving errors that impact end-users, you ensure a smoother and more reliable experience for everyone using the BMC Remedy or Helix platform.
- Security: Certain errors might hint at security vulnerabilities or unauthorized access attempts.
Common ARERR Message Categories and Examples
While there are hundreds of ARERR codes, many fall into common categories. Understanding these categories can help you anticipate potential issues. Here are some frequently encountered ones:
1. Database Connectivity and Operation Errors
These are some of the most critical errors, as they directly impact the system's ability to store and retrieve data.
- ARERR [350] : Database Error: This is a generic database error. The accompanying message will often provide more specific details from the database itself (e.g., SQL error codes). This could be due to incorrect SQL syntax in a filter or active link, a problem with the database server, or insufficient permissions.
- ARERR [340] : Database query execution error: Similar to the above, this indicates a problem with executing a SQL query. It might be a syntax error, a missing index, or a lock issue on the database table.
- ARERR [8756] : Database query interrupted: This often signifies that a database query took too long to execute and was timed out by the AR System server or the database itself.
Real-world Example: A user reports that they cannot save a new incident. You check the AR System logs and find `ARERR [350] : Database Error` followed by specific SQL error codes related to constraint violations or duplicate key entries. This indicates that the data being entered violates a database constraint, likely on a unique key field.
2. Workflow and Business Logic Errors
These errors occur when workflows (filters, active links, escalations) encounter logical issues, incorrect configurations, or try to perform invalid operations.
- ARERR [382] : Deadline is in the past: This often appears with escalations that are configured to run at a specific time, but the server's time or the escalation's scheduled time is misconfigured, leading to an attempt to schedule something that has already passed.
- ARERR [108] : Cannot perform this operation on a hidden field: This happens when a workflow tries to manipulate a field that is hidden from the user's view in the current form context.
- ARERR [339] : The syntax of the query is incorrect: This error points to a problem within a qualification or query string used in a workflow. It could be missing quotes, incorrect operators, or invalid field references.
- ARERR [71] : The value(s) for this field do not match the field's type: This indicates a data type mismatch. For instance, trying to store text in a numerical field or vice-versa.
Real-world Example: An administrator is building a new workflow for ticket reassignment. They write a qualification to find tickets assigned to a specific user but mistakenly use a field that isn't indexed, or a typo in a field name. The system throws `ARERR [339] : The syntax of the query is incorrect` when the workflow tries to execute, preventing the reassignment.
3. User and Security Permissions Errors
These errors relate to user authentication, authorization, and permissions to perform actions.
- ARERR [100] : Cannot establish a connection to the AR System server: This is a critical error indicating that the client application (like the User Tool or Mid Tier) cannot connect to the AR System server at all. It could be due to the server being down, network issues, or firewall problems.
- ARERR [109] : Security Error: This is a broad category indicating an authorization failure. The user might not have the necessary permissions to perform the requested action (e.g., modifying a record in a restricted form, accessing a specific view).
- ARERR [345] : The specified user or group does not exist: This error typically occurs when a workflow or an administrator attempts to assign a ticket or grant permissions to a user or group that has been deleted or misspelled in the system.
Real-world Example: A new employee joins the IT service desk but cannot log in to the Remedy client. The ARERR message might be `ARERR [109] : Security Error` when they try to access a form, indicating that their assigned group does not have read access to that form, or `ARERR [100] : Cannot establish a connection to the AR System server` if their account isn't properly configured in the AR System user form.
4. AR System Server Internal Errors
These are errors originating from within the AR System server's own processes.
- ARERR [9204] : Server group communication problem: In a server group environment, this indicates a failure in communication between the primary and secondary AR System servers. This could be due to network latency, firewall rules, or issues with the server group configuration.
- ARERR [7001] : Internal Error: This is a very generic internal AR System server error. It often requires deeper investigation into AR System logs and possibly contacting BMC support.
- ARERR [303] : An error has occurred processing the incoming request: This suggests that the AR System server received a request that it couldn't process due to an internal anomaly or an malformed request.
Real-world Example: During peak usage, users start reporting intermittent application slowness and occasional errors. The AR System logs reveal `ARERR [9204] : Server group communication problem`. This signals a potential issue with how the servers in the server group are coordinating, which could lead to load balancing failures or inconsistent data access.
Troubleshooting ARERR Messages: A Practical Approach
Encountering an ARERR message can be daunting, but a systematic approach makes troubleshooting manageable.
Systematic Troubleshooting Steps
- Identify the Specific ARERR Code and Message: The first and most crucial step is to note down the exact ARERR code (e.g., ARERR [350]) and the accompanying description.
- Check AR System Logs: This is your primary source of information. Key logs to examine include:
- AR System Log (
armonitor.log,arerror.log): Contains general server-side errors and events. - API Log: Logs all API calls made to the AR System server. This is invaluable for tracing the execution of workflows and identifying where an error occurred.
- SQL Log: Records all SQL queries executed against the database. Essential for diagnosing database-related ARERR messages.
- Mid Tier Logs: If the error occurs via a web browser, these logs are crucial for understanding client-side issues and communication with the server.
You can enable these logs through the AR System Administration Console under the "Server Information" -> "Log Files" tab. Be cautious when enabling detailed logging in production environments as it can impact performance.
- AR System Log (
- Reproduce the Error: If possible, try to reproduce the error under controlled conditions. This helps confirm the steps that trigger the ARERR and provides a consistent test case for your troubleshooting.
- Contextualize the Error:
- Who encountered the error?
- When did it occur?
- What action were they performing?
- Which form or application was involved?
- Search BMC Knowledge Base and Documentation: BMC provides an extensive knowledge base (KB) and documentation. Searching for the specific ARERR code and description can often yield pre-existing solutions or workarounds.
- Troubleshooting AR System server errors
- BMC Helix ITSM Documentation
- Common errors and troubleshooting in AR System
- Analyze Workflow/Configuration: If the error is related to workflow, carefully review the filters, active links, escalations, and other configurations involved in the user's action. Look for:
- Syntax errors in qualifications or workflow logic.
- Incorrect field references.
- Data type mismatches.
- Missing or incorrect permissions assigned to users/groups involved in the workflow.
- Check Database Health and Permissions: For database-related errors, verify the database server's status, check for any active locks, and ensure the AR System database user has the necessary permissions.
- Network and Server Health: For connectivity errors or server group issues, check network connectivity between servers, firewall rules, and the overall health of the AR System server and its underlying infrastructure.
- Consult BMC Support: If you've exhausted all other options and cannot resolve the issue, it's time to open a case with BMC Support. Provide them with all the relevant ARERR messages, log files, and a detailed description of your troubleshooting steps.

ARERR Messages in the Context of BMC Helix
While the core AR System engine remains the foundation, BMC Helix ITSM and its related components (like BMC Helix Innovation Suite) introduce new layers of complexity and new potential error sources. The principles of troubleshooting ARERR messages largely remain the same, but you'll also need to consider:
- Cloud-Specific Issues: In a cloud environment, network latency, managed services, and cloud infrastructure can play a role.
- Containerization (Kubernetes): If you are managing Helix on-premises using containers, errors related to pod health, service discovery, and resource allocation can manifest as ARERR messages.
- Integration Points: Helix often integrates with other systems. Errors might arise from faulty integrations rather than the core AR System itself.
- Microservices Architecture: Helix is moving towards a microservices architecture, meaning errors can originate from various independent services.
The core ARERR codes are still relevant, but you might see them in conjunction with other cloud-native logging and monitoring tools. The BMC Helix documentation is an excellent resource for understanding these specific environments.
