Verify the crontab Entries
After upgrading the DNCS, 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 If necessary, open an xterm window on the DNCS.
2 Type cd and then press Enter. The home directory of /export/home/dncs
for dbOptimizer, and that it contains no entry for camEmmDeleter. Follow these
instructions to inspect the crontab file.
1 If necessary, open an xterm window on the DNCS.
2 Type cd and then press Enter. The home directory of /export/home/dncs
becomes the working directory.
3 Type crontab -l and then press Enter. The system lists the entries in the crontab
file.
Note: The 'l' is a lowercase L.

4 Does the crontab file include an entry for dbOptimizer?
If yes, go to Examining the CED.in Entry (on page 85).
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 DNCS. When a DHCT has been
successfully staged, those EMMs associated with the staging process are no longer
needed and should be removed from the DNCS database. The dbOptimizer program
is configured to run by default each Saturday at 4 AM.
The /dvs/dncs/bin/CED.in file in the DNCS 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.
1 From an xterm window on the DNCS, type cat /dvs/dncs/bin/CED.in and then
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.

1 From an xterm window on the DNCS, type cat /dvs/dncs/bin/CED.in and then
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.

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 87).
