Identify the Authoritative MDRs

Identify the authoritative MDRs in your CMDB environment. For example, you want to allow updates to CIs from CA Configuration Automation that you identified as MDR1. You consider updates from Web Services that you identified as MDR2 as unauthoritative, and you want to send those requests to the TWA.

Follow these steps:

1. Open the NY Server IP Addresses policy, click Edit.
2. Enter MDR1 as the MDR Name Pattern.

   Note: If you want to exclude an MDR named MDR2, but you want to allow MDR1, MDR3, and so on, enter !MDR2 as the pattern.

3. Create a separate verification policy, such as MDR2 NY Server.
4. Enter the same information as in the previous policy except the following fields:
   1. Enter MDR2 as the MDR Name Pattern.
   2. Select Always Cancel the Entire Transaction as the Update Behavior.
   3. Select Always from the Write Data to TWA drop-down list.
5. Click Save.
