Service Manager Connector Bug: Uninstalled Software Relationships Persist. Learn How to Fix!

Table of Contents

The effective management of IT assets is a cornerstone of any robust IT infrastructure. Microsoft System Center plays a pivotal role in this, offering a suite of tools designed to streamline various aspects of IT operations. Among these, System Center Configuration Manager (SCCM) excels in endpoint management, including software deployment and inventory, while System Center Service Manager (SCSM) provides capabilities for IT service management, often acting as the authoritative Configuration Management Database (CMDB) for critical asset data.

The seamless integration between SCCM and SCSM through connectors is essential for maintaining a unified and accurate view of the IT environment. This integration ensures that asset information, including installed software, flows from SCCM’s discovery processes into SCSM’s CMDB, supporting various ITIL processes such as incident, problem, and change management. However, a specific issue has been identified where the Service Manager connector to Configuration Manager fails to accurately reflect the uninstallation of software, leading to persistent, outdated relationships within SCSM. This article delves into the intricacies of this bug and provides a comprehensive solution to restore data integrity.

Symptoms: The Tangible Impact of Data Discrepancy¶

Organizations relying on the integration between SCCM and SCSM may encounter a significant data discrepancy. Software that has been successfully deployed and subsequently uninstalled from client machines, as confirmed by Configuration Manager’s inventory, continues to be listed as “installed” in Service Manager. This leads to a scenario where the source of truth (SCCM) accurately reports the absence of software, while the CMDB (SCSM) holds stale and incorrect information.

The implications of such inaccurate data are far-reaching for IT operations. From a licensing compliance perspective, an inflated count of installed software can lead to over-licensing and unnecessary expenditure, or conversely, make it challenging to audit actual license usage effectively. For service desks and incident management, understanding the true software landscape on a user’s machine is crucial for efficient troubleshooting and resolution. Imagine an IT technician attempting to troubleshoot an application issue, only to find the application no longer exists on the user’s computer, as the CMDB data provided false information.

Furthermore, inaccurate software relationships impact change management processes. If a change is planned based on the premise that certain software is installed, but it isn’t, the change might fail or lead to unexpected outcomes. Reporting also suffers, as management reports generated from SCSM will present a skewed view of the enterprise’s software estate, hindering strategic decision-making. The core problem is a breakdown in the synchronization mechanism that should effectively remove these software-installed relationships in SCSM once the software is uninstalled and the change is inventoried by SCCM.

Delving into the Root Cause: The Missing Deletion Records¶

At the heart of this persistent data issue lies a breakdown in how Configuration Manager communicates software removal to Service Manager. The Service Manager connector relies on specific “software-deletion records” generated by Configuration Manager to trigger the removal of corresponding software-installed relationships in the SCSM CMDB. This mechanism is designed to ensure that the CMDB accurately reflects the current state of assets as reported by SCCM’s comprehensive inventory processes.

Prior to a particular update, Configuration Manager would reliably generate these deletion records whenever software was uninstalled from a managed client. These records acted as explicit instructions for the SCSM connector, informing it that a previously reported software installation was no longer valid and should be purged from the CMDB. This established a robust feedback loop, maintaining data consistency across both platforms.

However, a critical change was introduced in System Center 2012 Configuration Manager Service Pack 1 (SP1). This alteration, while likely intended to optimize or refine other aspects of Configuration Manager’s functionality, inadvertently affected the generation of these crucial software-deletion records. Specifically, it prevented the underlying database triggers responsible for writing these records from activating correctly. Without these deletion records being written to the SCCM database, the Service Manager connector had no signal to act upon. Consequently, even after Configuration Manager successfully identified and removed the software from its own inventory, Service Manager remained unaware of the change, leaving the outdated software-installed relationships intact. This architectural oversight created a silent but significant disconnect in the integration, leading to the data integrity issues observed.

The Comprehensive Resolution: Re-enabling Critical Triggers¶

The resolution to this persistent data synchronization issue involves directly addressing the root cause within Configuration Manager: re-enabling the database triggers responsible for generating software-deletion records. By restoring the functionality of these triggers, Configuration Manager can once again properly inform Service Manager about software uninstallation events, allowing the connector to perform its intended cleanup actions. This process typically requires administrative access to the Configuration Manager site database and careful execution to ensure the integrity of your SCCM environment.

Crucial Pre-Fix Steps¶

Before attempting any modifications to the Configuration Manager database, it is paramount to follow best practices for database management:

1. Backup the SCCM Database: This is the most critical step. A full backup of your Configuration Manager site database ensures that you can revert to a stable state if any unforeseen issues arise during the trigger re-enablement process.
2. Test in a Lab Environment: Whenever possible, thoroughly test the resolution steps in a non-production lab environment that mirrors your production setup. This allows you to validate the procedure and observe its effects without risking your live systems.
3. Understand SQL Permissions: Ensure that the account used to execute the database commands has the necessary permissions (e.g., db_owner or equivalent) on the Configuration Manager site database.
4. Coordinate with Database Administrators: If you operate in an enterprise environment, collaborate with your database administration team. They can provide expertise, assist with backups, and ensure proper change control procedures are followed.

Conceptual Steps for Identifying and Re-enabling Triggers¶

While specific SQL commands might vary slightly based on your exact SCCM version and database configuration, the general approach involves identifying the specific database tables and their associated triggers that manage software inventory and deletion records. The process will typically involve:

1. Connecting to the SCCM Database: Use SQL Server Management Studio (SSMS) to connect to the SQL Server instance hosting your Configuration Manager site database.
2. Identifying Affected Triggers: You will need to query the database to list the triggers associated with software inventory-related tables. The original KB article (2874780) typically provides the exact trigger names or tables to focus on. These triggers are usually designed to log changes, including deletions, into specific views or tables that the SCSM connector monitors.
3. Enabling the Triggers: Once identified, you will execute SQL ALTER TRIGGER statements to enable any triggers that are currently disabled or have been inadvertently altered. For example, a command might look conceptually like ALTER TRIGGER [TriggerName] ON [TableName] ENABLE;
4. Verifying Trigger Status: After execution, re-query the database to confirm that the target triggers are now in an enabled state.

Post-Fix Verification¶

After successfully re-enabling the triggers, it’s essential to verify that the fix is working as intended:

1. Trigger a New Hardware Inventory: On a few test client machines where software was previously uninstalled but persisted in SCSM, initiate a new hardware inventory cycle from the Configuration Manager client. This will ensure SCCM re-evaluates the software state.
2. Run the SCSM Connector Synchronization: Manually initiate a full synchronization cycle for the Configuration Manager connector within Service Manager. This will prompt the connector to process any new deletion records generated by SCCM.
3. Verify in SCSM: Navigate to the Configuration Items in Service Manager and check the affected computers. Confirm that the previously uninstalled software relationships are now correctly removed. You might also check related views or reports in SCSM.
4. Monitor for Any New Issues: After implementing the fix, monitor your SCCM and SCSM environments for a few days to ensure no new, unforeseen issues have been introduced and that synchronization continues to function correctly.

By carefully following these steps, you can successfully re-establish the critical link between Configuration Manager’s inventory and Service Manager’s CMDB, ensuring accurate and up-to-date software asset information.

Leveraging SCCM and SCSM for Superior IT Asset Management¶

The resolution of this bug significantly enhances the accuracy and reliability of your IT asset management processes. A precise CMDB is not merely a database; it is a strategic asset that underpins efficient service delivery, robust compliance, and informed decision-making. Understanding the complete lifecycle of software, from installation to uninstallation, is crucial for maintaining a healthy and manageable IT environment.
