When sites are being upgraded, the dhctStatus utility may occasionally be in the 
process of polling DHCTs. Additionally, the signonCount utility may be active in 
system memory. Cisco engineers have discovered that upgrades proceed more 
smoothly when the dhctStatus utility is not actively polling DHCTs and when the 
signonCount utility is not active in system memory. The instructions in this chapter 
guide you through the steps to terminate polling associated with the dhctStatus 
utility and to remove the signonCount utility from system memory. 

 

Follow these instructions to determine whether the dhctStatus utility is actively 
polling DHCTs, and then to terminate the polling operation, if necessary. 
1  If necessary, open an xterm window on the DNCS. 
2  Type dhctStatus and press Enter to display the dhctStatus menu. 
3  To terminate the polling operation, follow these instructions. 

a  Type p and then press Enter. The system displays a polling menu. 
b  If applicable, type t and then press Enter. The system terminates the polling 

operation. 

c  Press Enter to return to the main menu. 
d  Press q and then press Enter to exit the menu. 

4  Type ps -ef | grep dhctStatus and then press Enter to determine if all of the 

processes are terminated. 
Example: 

dncs 12514 12449 0 13:50:27 pts/3 0:00 /bin/ksh /dvs/dncs/bin/dhctStatus 
dncs 12556 12514 0 13:50:28 pts/3 0:01 /usr/local/bin/perl 
/dvs/dncs/bin/DhctStatus/dhctStatus.pl 
dncs 12681 12632 0 13:50:54 pts/10 0:00 grep dhct 

5  Type kill -9 <processid> and then press Enter for each process ID displayed in 

step 4. 
Example: Kill -9 12556  

6  Repeat steps 4 and 5 for any process that continues to display active. Once 

completed the system should only display the grep process. 

 

1  If necessary, open an xterm window on the DNCS.
