Track Progress of the emmDistributor With the emmlst Utility 

6-1 

The camAuditor process in the DNCS keeps EMMs from expiring and stores newly 

encrypted EMMs in the DNCS database. The DNCS then uses the emmDistributor 

process to refresh DHCTs with their EMMs. The emmDistributor process runs 

continuously. It constantly cycles through the database, assigning EMMs to the 

appropriate DHCT. 
With DNCS version 1.5, it typically takes several days for the emmDistributor 

process to cycle through a database with more than 100,000 DHCTs. System 

operators and Cisco engineers may want to know how far through the database the 

emmDistributor process is at any given time. Cisco engineers developed the emmlst 

utility to keep track of the progress made by the emmDistributor process as it cycles 

through the DNCS database. 

The emmlst utility is only useful at sites that support version 1.5.x of DNCS 

software. The emmDistributor process at sites running DNCS software later than 

version 1.5.x is multi-threaded. When the emmDistributor process is multi-threaded, 

there is no single point in the database from where EMMs are read and distributed. 

For multi-threaded systems, the cycle time of the emmDistributor process is far 

shorter; hence the utility is no longer useful.
