Examining the CED.in Entry
Our engineers developed the dbOptimizer program to delete EMMs that are no
longer needed by DHCTs. Most EMMs are assigned to DHCTs during the staging
process when DHCTs are prepared for deployment in the homes of subscribers.
These EMMs are also stored in the database of the EC. When a DHCT has been
successfully staged, those EMMs associated with the staging process are no longer
needed and should be removed from the EC database. The dbOptimizer program is
configured to run by default each Saturday at 4 AM.
