Environment

Release : 21.2.8 & 21.2.10

Component : NQRAHV - NETQOS RA HARVESTER

Cause

In 21.2.8 and higher, the MySQL anonymous user has been removed. Customers running NFA Harvester with a revision history that dates back to NFA 9.x will have MySQL procedures which refer to the anonymous user. We changed the definers to use the root user in more modern versions which did fresh installs. 

Resolution

1. Download the patch to the effected harvesters.

2. Extract the patch.

3. Read the readme to apply the patch.

4. Repeat on each harvester with the issue.

Additional Information

These mySQL changes will be included in the NFA 21.2.12 release.
