Verify the crontab Entries 
Verifying the crontab Entries 
After upgrading, inspect the crontab file to verify that it contains an entry for 
dbOptimizer, and that it contains no entry for camEmmDeleter. Follow these 
instructions to inspect the crontab file. 
1  From the dncs remote terminal window, type 
cd
 and press Enter. The home 
directory of /export/home/dncs becomes the working directory. 
Type 
crontab -l
 and press Enter. The system lists the entries in the crontab 
file. 
Note: The 'l' is a lowercase L. 
3  Does the crontab file include an entry for dbOptimizer
 
If yes, go to Examining the CED.in Entry (on page 64). 
 
If no, call Cisco Services for assistance. 
 
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.  
The /dvs/dncs/bin/CED.in file in the EC contains a value that represents a number 
of days. The dbOptimizer program is designed to delete unneeded EMMs that are 
older than the number of days specified in the CED.in file.  
In this procedure, you will examine and change, if necessary, the number of days 
specified in the CED.in file. 
Note: Our engineers recommend the default value of 90 days. 
From the root remote terminal window on the EC, type the following command 
and press Enter. The system displays the number of days that EMMs will be 
retained. EMMs that are older than this number of days will be deleted by the 
dbOptimizer program when it runs each Saturday. 
cat /dvs/dncs/bin/CED.in
  
2  Are you satisfied by the number of days specified by the CED.in file? 
 
If yes, go to Adding Custom crontab Entries (on page 65). 
 
If no, go to step 3 to edit the CED.in file.
