Running CODA

Startup the processes

Start the following programs in the order below and in different xterm windows

1.)msqld
2.)minicom (telnet roc1)

cntrl-A P E to setup communication speeds

reboot to be sure ROC is alive

3.)et_start -v -s 70000 -n 200

you may need to delete the old memory file /tmp/et_sys_DAQ

error message

~ >et_start
et_netinfo: error in gethostbyaddr
et_udpreceive: bind error
et SEVERE: et_listen_thread: problem opening socket

The above error message happened when I took the DAQ system to the IAC. The solution is to add the new IP addresss for the DAQ machine to the /etc/hosts file

For example

192.168.40.150  daq1.physics.isu.edu    daq1

4.)rcServer

5.) coda_eb -i -s DAQ -n eb1 -t CDEB

6.)coda_er -i -s DAQ -n LDS_ER -t ROC

7.) runcontrol

Select run configuration

Creating run Configurations

The following describes how to make a run configuration file

use cedit to save a configuration to the data base (best to copy an old configuration)

Then

1.) lauch dbedit application

>dbedit

2.) select "localhost"

3.)click on "localhost" tab

4.) select "LDS" data base

5.) now start copying other tables into a new tabl

a.) SIS3610 copy to table SIS3610gem b.) SIS3610_option copy to table SIS3610gem_option c.) SIS3610_pos copy to table SIS3610gem_pos

6.) go to new copy and change location of executable code to a new directory (row 1 column "code")

The tables won't reload if you jsut stop runcontro. restarting the msql server didn't work

how to get the new runconfiguration to show up in runcontrol?

Th library for the ADC needs to be downlaoded by hand into the ROC. On the ROC terminal window type

ld < v792Lib.o

Using local network card

I decided to connect the ROC directly to the second 1 Gigabit ethernet card on the host in order to avoid setting up a firewall which makes our sys admin guys happy and allows CODA to work.

I had to tell the ROC to alias the new host names in the boot script

so in the file CODA/bootscripts/roc1.boot

I added the line

hostAdd "daq1","10.1.1.1"

You can do this on the roc as well and then on the ROC you can check the lookup tables using the command

-> hostShow                                                                     
hostname         inet address       aliases                                     
--------         ------------       -------                                     
localhost        127.0.0.1                                                      
roc1             10.1.1.2

I had incorrectly connected my EB to my ER system

ROC won't load VxWorks Kernel

If you have anout output to stdout from a .cshrc or .tcshrc login script then the ROC will have trouble loading the kernel.

I ran into this one when I deciced to "source CODA/setup" in order to define my CODA environmental variables when I log in. The setup script did a "echo" and this caused the ROC to stop loading the kernel. When I was watching via minicom all I saw was the word "Loading...".

coda_eb constructor faile

~ >coda_eb -i -s DAQ -n eb1 -t CDEB constructor failed : Couldn't setup listening socket on any port: Cannot assign requested addressNS_ServerInit (dp_MakeRPCServererror : Couldn't setup listening socket on any port: Cannot assign requested address ) Segmentation fault

coda_eb couldn't resolve the name server address

change /etc/hosts file so it has the right IP number for daq1.

et_start Segmentation fault

Solution: Try removing the file /tmp/et_sys_DAQ.
