Frequently Asked Questions
A.
After starting the database, you should see two sockets (listening and non-listening) connecting to
the database on each of the remote servers on port 9999. You can check them by using the netstat
-an | grep 9999 command.
For example, the following output of the netstat command shows that the server (172.22.97.194) has
both the listening and non-listening sockets binding on port 9999 to echo the four remote servers
(172.22.97.192, 172.22.97.193, 172.22.97.195 and 172.22.97.191).
# netstat -an|grep 9999
tcp 0 0 172.22.97.194:9999 172.22.97.195:48652 ESTABLISHED
tcp 0 0 172.22.97.194:9999 172.22.97.191:42732 ESTABLISHED
tcp 0 0 172.22.97.194:54563 172.22.97.195:9999 ESTABLISHED
tcp 0 0 172.22.97.194:39342 172.22.97.191:9999 ESTABLISHED
tcp 0 0 172.22.97.194:9999 172.22.97.192:40207 ESTABLISHED
tcp 0 0 172.22.97.194:41815 172.22.97.192:9999 ESTABLISHED
tcp 0 0 172.22.97.194:9999 172.22.97.193:33196 ESTABLISHED
tcp 0 0 172.22.97.194:43269 172.22.97.193:9999 ESTABLISHED
tcp 0 0
If you can not see both listening and non-listening sockets binding on port 9999 for each of the
remote servers, the database is not running properly. Check that you have the correct replication
group members in your /home/isa/.arroyorc file.
Serviceability and Manageability
Q.
How do I check the calypso server status?
A.
Log in to the server as root and enter the cat /proc/calypso/status/server_settings command.
Q.
How do I check central processing unit (CPU)?
A.
Log in to the server as root and enter the cat /proc/cpuinfo command.
Q.
How do I check the ISA server status?
A.
Log in to the server as root and enter the /home/isa/IntegrationTest/show_calypso_services
command.
Q.
How do I check the kernel network driver version?
A.
Log in to the server as root and list the e1000.ko file to check the date and time it was created using
the following command:
ls -l /lib/modules/<current running kernel name>/kernel/drivers/net/e1000/e1000.ko
The following example shows that the e1000.ko file is based on the kernel
2.5.18-53.el5.kernel.2_6_18.2009.01.08.01.
# ls -l /lib/modules/2.6.18-53.el5.kernel.2_6_18.2009.01.08.01/kernel/drivers/net/e1000/e1000.ko
-rw-r--r-- 1 root root 2617502 Jan 8 18:13
/lib/modules/2.6.18-53.el5.kernel.2_6_18.2009.01.08.01/kernel/drivers/net/e1000/e1000.ko
Q.
How do I stop, start, and, restart the Apache server on the CDSM?
A.

# /arroyo/www/bin/apachectl start
# /arroyo/www/bin/apachectl restart
