Products

• DX Unified Infrastructure Management (Nimsoft / UIM)
• CA Unified Infrastructure Management On-Premise (Nimsoft / UIM)
• CA Unified Infrastructure Management SaaS (Nimsoft / UIM)

Issue/Introduction

Need details on what happens when the nas reorganize process is run.

Environment

Release: Any
Component: nas, any version

Resolution

The reorganize command will take the NAS into maintenance mode, stopping all service modules and performs a VACUUM of the database.db and the transactionlog.db. All services are started upon completion.

The database size is supposed to reduce the file size after vacuum has been run. Vacuum (i.e. SQLLite terminology) is only run if there is a quiet period where there aren't any alarms to log.
