CODA restart instructions

If CODA has crashed or if there is some reason to restart CODA (such as one of the crates is causing reset errors) then perform the following steps:

• Open a terminal and switch users to a-onl (execute "su a-onl" without the quotes
• The computer should now have a prompt like a-onl@adaql2 ~]$
• From here type "startcoda" without the quotes
• The startcoda script will kill the previous version of CODA and then start a new one
• Once the Run Control interface comes up, clock on menu, then connect
• You should now have the option to click on the configure botton (The button that looks like a wrench crossing a screwdriver)
• After that is finished CODA should operate as normal

Further CODA troubleshooting

Below are possible errors and their solutions

If CODA says it can't connect to the msql database

• Go back to your terminal and type "kcoda" without the quotes
• Type "startcoda" without the quotes
• This should resolve the problem.
• The reason is sometimes the kcoda script will not kill all the processes and some escape

If a pop up says that a component is needing or creating a reset

• Try resetting CODA (the button that has two backward arrows)
• Before you resume normal operations of the DAQ, go to each of the component windows (the windows that open after you execute startcoda) and hit enter
• You should now have a prompt that looks like -&62; If this is correct type "reboot" without the quotes
• If the prompt looks like [VxWorks]: you should hit ctrl+x on the keyboard
• After doign this for all the components and waiting for them to boot, startcoda coda as listed earlier in this section

This is the newest version of CODA and as such there may be issues. If there are any issues please e-mail lselvy@jlab.org and report them so that this page can be updated.

BigBite and RHRS Lecroy High-voltage (HV) GUI

• Login as adev@adaqlX (any machine) and run:
  • hvgui_bb -- for the BigBite/HAND group of three crates
  • hvgui_hrs -- for the RHRS bottom HV crate
• (The backend servers run under the adev account, but you can actually bring up the gui from adaq@adaqlX too.)

  You should always try the above command first.

• If the backend is killed/dead then you need to ssh to the appropriate host and run start_hvgui_XXX where XXX is 'bb' or 'hrs'.
  • The above 'hvgui_XXX' command will prompt you with what to do if the GUI doesn't pop up. Follow those instructions first since the machines in use may have changed.
  • As of this writing, you need to login as adev@adaql5 (for BB/HAND GUI), or adev@adaql9 (for the LHRS GUI) and run 'start_hvgui_XXX', where XXX is 'bb' or 'hrs':
    • adev@adaql5 % start_hvgui_bb -- for the BigBite/HAND group of three crates
    • adev@adaql9 % start_hvgui_hrs -- for the RHRS bottom HV crate

==============================================================================

Scaler GUI Control

To Open the scaler GUI in the Counting House here are the steps:

• Make sure you are in an a-onl account
• If you are not ssh to a-onl@adaqln where n is 1 - 9
• Once there, type HANDscaler or BBscaler for the HAND or BigBite scaler GUIs respectively

==============================================================================

CAMAC Threshold Control

To Check the Thresholds for the bbite Weldment here are the steps:

• Make sure you are in an a-onl account
• Type the following command `~/bbite/bin/threshold_LeCroy -g ****`
• Where **** is:

Value of ****	Threshold Values for:
E	Layer E of the BB Trigger Plane
dE	Layer dE of the BB Trigger Plane
dEtrigger	The dE Trigger Thresholds
ND_veto	The Veto Layer of HAND
ND_N1	Layer 1 of HAND
ND_N2	Layer 2 of HAND
ND_N3	Partial Layer 3 of HAND
ND_N3N4	Partial Layers 3 and 4 of HAND
ND_N4N5	Partial Layers 4 and 5 of HAND
ND_N6	Layer 6 of HAND
ND_AllU	All Planes of HAND in BBCAMAC2 (upper crate)
ND_AllD	All Planes of HAND in BBCAMAC3 (lower crate)

• An example is as follows.
• To Check the threshold values for the E plane:
• type `~/bbite/bin/threshold_LeCroy -g E`

To Set the thresholds it is similar to the top except the flag g is replaced with s and values follow

Example Below

• To Set the thresholds for the E plane to 10mV
• type the command `~/bbite/bin/threshold_LeCroy -s E 10mV

==============================================================================

EVe Tracking GUI

Make sure you start the analyzer from /adaqfs/home/adaq/e07006/HallATest as the rootlogon.C is there.

The rootlogon.C loads in the necessary libraries for HAND, BBite, and the EVe tracking gui.

Once in the analyzer the proper syntax is:

• EVe *sim = new EVe(gClient->GetRoot(),400,700)
• Where 400,700 are the sizes of the window
• Then point your newly instantiated EVe at your rootfile as follows:
• sim->initRun(filename)
• Where filename will be rootfiles/your-root-file.root

Once the GUI is open just follow the on screen directions

==============================================================================

N->Delta Charge Sum

The script ~adaq/extract_ndelta_charge.sh sums up the BCM U3 and D3 charges
collected for a range of runs. The information is taken from the end-of-run records.

Usage

  ~adaq/extract_ndelta_charge.sh startrunnumber endrunnumber

Problems with the ROCs Booting

If you're having trouble with one of the bigbite weldment ROCs (bbts1, 5, 8, 9, 10) booting please make sure the following parameters are correct

In the Component window if the prompt is '->' then:

• Type bootChange in the component window
• Note backspace doesn't work here, but ctrl+h replaces backspace
• Be careful and hit return (enter) and until you are returned to the prompt
• Check the parameters above against the file /adaqfs/home/a-onl/boot_param_bb
• If there is a problem, type bootChange and hit enter until you get to the line where the problem occurs
• Type the correct value and hit enter
• Reboot the ROC by typing "reboot" at the prompt or by hitting ctrl+x

If the prompt looks like [VxWorks] do the same as above except type c (lower case) instead of bootChnage

==============================================================================

Moving the spectrometer

To move the spectrometer go to the Hall A Tools screen of the shift leader computer

• Go to the tooldbox menu at the bottom of the screen
• Select the bogies_N where N is the spectrometer you wish to move (left or right)
• On the screen in the upper left box there are four switches
• Click the PSM Enable box and wait until the indicator in the section to the right says "YES"
• Click the DM Enable box and wait until the indicator in the section to the right sats "YES"
• Click the Brake release box and wait until the indicator in the section to the right sats "YES"
• Click the Clamp release box and wait until the indicator in the section to the right sats "YES"
• In th upper right box set the velocity to a number &60;= 600
• The volecity works as follows:
• &60;0 is Clockwise (LHRS smaller angle RHRS greater angle)
• &62;0 is Counter Clockwise (LHRS greater angle RHRS smaller angle
• Then use the vernier to align with the 31 degree mark for the LHRS or the 34 degree mark for the RHRS
• Once it is almost in position click the clamp release box, followed, by the brake release, then DM enable, PSM enable
