Track Progress of the emmDistributor With the emmlst Utility
Overview
Introduction
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
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.
Restricted to SR 1.5.x Systems
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.
