Catalog Overview
This section provides information about catalog updates available with every release.
Managing the infrastructure
After you complete the initial configuration of BigFix Inventory, learn how to manage components of its infrastructure: VM managers, server, database, and data sources.
- Software Scan Status
- Computer statuses
  Computer statuses provide information about the condition of the computers that are monitored by BigFix Inventory. To properly discover the installed software and measure its license metric utilization, ensure that computers in your environment work correctly.
- Managing VM managers
  VM managers are pieces of software that create, manage, and monitor virtual machines. You configure connections to VM managers so that BigFix Inventory can gather data that is required to calculate utilization of license metrics in virtual environments.
- Administering the server
  Perform administering tasks on your server to configure advanced settings, or restart its services.
- Administering the database
  Perform administering tasks on your database to keep it in good condition, protect your data, or configure additional settings.
- Datasource deletion process for DB2
  This section provides step-by-step instructions for database administrators to compile, execute, monitor, and troubleshoot the DB2 datasource deletion stored procedure using standard DB2 CLI commands.
  - Step 1: Pre-Execution Environment Setup
    Step 1 includes the process for the pre-execution environment setup.
  - Step 2. Executing DBO.DELETE_DATASOURCE_DATA via DB2 CLI
    Step 2 includes the deletion process.
  - Step 3: Live Monitoring via DB2 CLI
    Step 2 includes live monitoring using the DB2 CLI.
  - Step 4: Post-Execution Verification and Cleanup
    Step 4 includes the post-execution verification and cleanup of the database.
  - Step 5: Risk Mitigation & Rollback Strategy
    Perform a full restoration using the database backup generated during Step 1, point 3. Use the procedural guidelines for recovery: Inventory/admin/t_db2_restore.html.
  - Step 6: Common CLI Errors & Resolution Checklist (Troubleshooting)
    Check the list of common CLI errors and their resolutions.
- Removing inactive computers
  When you decommission a computer in your infrastructure, it continues to report to BigFix Inventory. The data is still collected from this computer, and displayed on the metric reports. To ensure that all infrastructure changes are reflected in BigFix Inventory, you should remove each decommissioned computer from BigFix. If you cannot remove this computer from BigFix for a valid reason, you can use an alternative solution, and decommission the computer in BigFix Inventory.
- Managing data sources
  Computers in an organization can be divided into organizational units, and can be monitored by multiple BigFix infrastructures. Each infrastructure is referred to as a data source. Data from multiple data sources can be imported to one instance of BigFix Inventory.
Software inventory and license utilization
You can classify the discovered software so that reports in BigFix Inventory reflect your entitlements and properly show utilization of license metrics by particular products.
Managing security threats
Learn how to use BigFix Inventory to manage security threats in your environment. You can view whether any of the installed components is prone to any Common Vulnerability and Exposure (CVE).
Tutorials

Step 2. Executing DBO.DELETE_DATASOURCE_DATA via DB2 CLI

Step 2 includes the deletion process.

Overview and parameters

CALL DBO.DELETE_DATASOURCE_DATA({param1}, {param2}, {param3})


Parameter	Type	Description	Recommended Default
param1	INTEGER	The ID of the BFI Datasource to delete (matches dbo.datasources.id).	Target DataSource ID (e.g., 1)
param2	INTEGER	Row chunk size per transaction commit. Defaults to 5000 if <= 0 or NULL.	5000
param3	INTEGER	Controls Foreign Key constraint handling. Set to 0 to disable/enable FKs, or 1 to bypass FK toggling.	0 (Normal) / 1 (Testing) Note: Choose this to default as 0.

Optimization & Operational Tips

Batch Size Optimization: The default size of 5,000 rows per transaction commit is optimized for environments with up to 35,000 endpoints. For larger datasets, for example ~105,000 endpoints, increase the batch size to 10,000 to improve execution performance.

The procedure invokes complete removal of the data associated with the selected datasource.

The operation consists of the following stages:

Disable Foreign Keys: Alters FK constraints to NOT ENFORCED.
Staging: Populates batch numbers in dbo.batch_delete_staging.
Batched Execution: Loops through batches in committed chunks.
Metadata Cleanup: Purges sub-dimensions & standalone tables.
FK Enforce & Check Integrity: Restores referential integrity.

Execution of the Stored Procedure

Standard Execution (Full FK Disable/Enable Handling)

Runs all stages, safely disabling FKs at the beginning and re-enforcing/checking integrity at the end.
