Troubleshooting issues with BMC Helix CMDB

Here are some common problems that can arise in  BMC Helix CMDB implementations:

• Import and reconciliation take significant time
  Make sure that only business-critical information is stored in the BMC Helix CMDB . Use federation for access to real-time or secondary information. Make sure that the database server is connected to  AR System through a 100MB or 1GB network link. If you add custom workflow to BMC Helix CMDB  forms, test it with high data-load scenarios and confirm that you do not see time-outs.
• Reconciliation Engine cannot identify instances
  Make sure that proper discovery options are used so identification attributes have non-null unique values.
• Configuration items have multiple instances (duplicates)
  Make sure that import datasets have accurate data and that identification rules are working correctly for each dataset.
• Class Manager changes are left pending 
  Only change the class model if absolutely required. Restrict access in the Class Manager to a single user. Make attribute changes one at a time and wait for changes to complete before proceeding. Changes to BMC_BaseElement can take two hours or longer.
• Class model is out-of-sync with underlying AR System  forms
  Except for the look and feel, do not use BMC Remedy Administrator to edit BMC Helix CMDB -related forms in AR System . Always use the BMC Helix CMDB  user interface instead.
• Adapter.OpenConnection completed with errors issued StartDataHandlers: Vendor Data Handler failed to start
  Verify that you specified the correct  AR System server user name and password. Also test the external data store connection by using the Test Connection button on the Connection Settings tab before you trigger the data exchange.
• Filter/escalation 'set fields' process timed out before completion. Set fields active link running a process failed
  From the AR System Administration Console, click System > General > Server Information > Timeouts. Also increase the Process Timeout setting for AR System server . The default value for the Timeout setting is 5 seconds.
• Cannot run the requested process. Set fields active link running a process failed
  Verify whether the installer copied the aiexfer utility in the  AR System installation Directory. If not, verify whether BMC Atrium Integration Engine was successfully installed.
• Required field cannot be reset to a NULL value PCT:Product Catalog
  Product Categorization Tier 1" - Ensure that following fields Category, Type, Item and Manufacturer Name are mapped. Dataset which you are using for Data transfer should be selected as Trusted in Dataset form.
