Frequently Asked Questions
Q.
How do I check the Streamer static ARP table?
A.
Log in to the server as root and enter the following command:
# cat /arroyo/test/ArpTable
ip 192.168.2.42 mac 000000000002
ip 192.168.2.43 mac 000000000002
Q.
How do I view the ARP Table dump file?
A.
Log in to the server as root and enter the following command:
# echo 1 > /proc/calypso/test/arp_dumpstate
Q.
How do I recover the system from the kernel debugger (KDB) after a reboot?
A.
If the server starts the KDB tool instead of rebooting, modify the /etc/grub.conf file as follows:
kdb=off panic=1
kernel /boot/vmlinuz-2.4.32avs ro root=/dev/hda1 console=tty0 console=ttyS0,115200
kdb=off panic=1
Q.
What do I do if the KDB prompt is displayed when the server restarts after a failure?
A.
Boot into single user-mode (see the “Kernel Crash” section on page A-16).
Q.
How do I destroy an individual ISA stream?
A.
Use the Delete button on the Stream Monitor page. See the “Stream Monitor” section on page 5-16
for more information. Alternatively, you can enter the following commands:
# su - isa
# cd ~/IntegrationTest
# ./list_all_streams
# cd ~/Streaming/client
# ./run_client
2 -> Stream
<name – as retrieved above>
24 -> Destroy
If this does not work, for example, the stream just restarts, then the problem is not in the ISA
subsystem.
Q.
How do I identify any holes in the content?
A.
Log in to the server as root and enter the following commands:
# echo 2 > /proc/calypso/tunables/cm_logserverinfo
# cat /arroyo/log/serverinfo.log.01132009
Look at the last two lines of output. If there are no holes, the last two lines should be the following:
BeingDeleted=0 HasHoles=0 CopyHoles=0 SectorHoles=0
Object Status Check Complete.
Q.
How do I clear cached video blocks (data cache) on the Streamer?
A.
Log in to the server as root and enter the echo 1 > /proc/calypso/test/clearcache command.
Q.
How do I clear the data cache in memory?
Log in to the server as root and enter the echo 1 > /proc/calypso/test/clearmem command.
