Running CODA
Startup CODA's processes
2.6.2
Startup CODA programs in separate xterminal sessions
type the following to setup the CODA environmental variables
source CODA/2.6.2/setup
start up msqld, et_start, rcplatform
coda_eb_rc3 -i -s DAQ -n eb1 -t CDEB
coda_er_rc3 -i -s DAQ -n LDS_ER -t ER
login to the ROC (rocdaq1) and start the process
ssh root@rocdaq1
coda_roc_rc3 -t ROC -n rocdaq1
now startup the runcontrol GUI
rcgui
2.6.1
Start the following programs in the order below and in different xterm windows
(need to do: source CODA/setup)
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
The following fixed the above message
add the line
10.1.1.1 daq1.physics.isu.edu daq1
to /etc/hosts file
According to Dave Abbott:
In looking at the ET code it seems that the ET system is checking all active network ports on a particular host and it gets a list of valid IP addresses (in your case 10.1.1.1 and 130.50.3.210). However it then attempts to get a hostname associated for each IP address (using gethostbyaddr). In your case 130.50.3.210 returns "daq1" but 10.1.1.1 returns <null> hence the error. In principle the hostname is not required for anything in particular, but the ET system does not start up because of this.
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
Download configuration to ROC
- Click COnfigure in the Runcontrol GUI
- select V775_TDC from the pull down menu
- click the download button in the runcontrol GUI
You should see message appears on several of the open windows. You should see information in the ROC window. If you see error messages check that you loaded the libraries with the commands -> ld <v792Lib.o -> ld < v775Lib.o
Prestart
Clicking the "Prestart" button in the GUI will begin initializing modules for the run
You should not see any error messages in the terminal windows.
Run
Click "Go" in the runcontrol GUI will start a data acquisition
debug FAQ
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 localdaq 10.1.1.1 daq1 value = 0 = 0x0
Incorrect number Argument when downloading
daLogMsg: Downloading configuration "SIS3610" Incorrect number of Arguments passed for ROL = 1 daLogMsg: Incorrect number of Arguments passed for ROL = 1
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 couldn't resolve the name server address
change /etc/hosts file so it has the right IP number for daq1.

Solution: Try removing the file /tmp/et_sys_DAQ.

Download run failed (UDP?) =

The above was because the computer name was not correct
changed
host name : localdaq
to
host name : daq1
now
