NIM crates are NOT checked by software. If they fail you might notice problems with the trigger etc. So wonder through the various barracks, look at crates and listen to a possible sound of alarm. If a NIM crate is faulty (dead or alarming) the fan unit might be bad and the power supply ok. If you want to change the fan unit and cables are in the way, LABEL them before you disconnect them!

In general:

• Log on to hh (any of h2,....,hg), account onl
  from the online Workstations: type "hhterm"
• Everything (including the logon) MUST be lowercase unless stated otherwise.
• Type "all top -I" to find out which machine is most idle and logon there to run the task.
• It IS possible to run a given task on more than 1 machine, but usually this will be UNREASONABLE. So check on whether your task already runs on one of the riscs.
• Global sections: They MUST be viewed by pawX11 on the machine the task runs.
• HBOOK files: they can be viewed from any machine
• To stop the task:
  ps -x shows you the current tasks : read its id
  kill -9 id stops it

True shared pawc for HBOOK/pawX11

• With the new library $NEWCERNLIBA we can now map PAWC directly into shared memory (as on VAX/VMS). This means: no copying, no extra copy of pawc, no bookkeeping needed anymore, and you can see your histos grow in real time (event by event) WITHOUT overhead in time or memory!
• To use the new shared memory feature:
  • remove all CALLs to ICOPGL !!!!
  • remove all CALLs to ICREGL and IMAPGL (if used for hbook!) (The calls above are NOT compatible with the new feature)
  • remove your "COMMON/PAWC/.... " line EVERYWHERE
  • remove CALL HLIMIT and replace it by CALL HLIMAP(100000,'NAME'), 100000 would be your size limit as previously in HLIMIT, NAME is your global section name. (The maximum size for HLIMAP is 1 Million words) (Only UPPERCASE for NAME) CALL HLIMAP must be done BEFORE any other HBOOK call!
  • start pawX11 glo name maps you to your global section greset id clears histo id (immediately), id=0 clears all
  • There is no need to change to //pawc !
• Note: The global sections will be deleted automatically when not used. The Deletion can take up to 15 minutes. If you want to delete the section manually: "gsshow" lists allocated global sections "gsdelete name" deletes the global section "name" (verify with another gsshow. If sections does not get deleted: It is attached by a program or pawX11)
• Note: If you increase your shared PAWC (by increasing the size in HLIMAP) and use the same name: You must FIRST delete the section BEFORE you start the program
• Note: Global sections can be attached only at the machine that created them!
• IMPORTANT: BEFORE choosing the name of your global section: edit the file /us0/onl/global.sections (h*) choose a name that doesn't exist yet and enter this name into the file

Testbeam, load frontends and DAQ after power up

1. Switch on Fastbus crate (make sure the "BH" LED is OFF)
2. Boot my (if it has been booted with FB crate off) To test this: "mt -f /dev/CHIP rewind" if it says" no such device" you must boot
3. load of SVX CHI

        On my:                              On any terminal server:
        connect_CHISVX              connect CHITEST4
   
        ctrl C                      ctrl C
        host 9600                   host 9600
        tra                         tra
                          	       	 
        ... login as chip pw ********       ... login as chip pw ********
        ctrl A                              ctrl A
        lo,p='get svx'              lo,p='get svx'
        ... wait until loaded               ... wait until loaded
        go 30000                    go 30000
        Ctrl-\ C                            ... BREAK
                                            ... DISCONNECT
        

4. load of primary CHI

        On my:                              On any terminal server:
        connect_CHIMAIN             connect CHITEST3
   
        ctrl C                      ctrl C
        host 9600                   host 9600
        tra                         tra
                                    
        ... login as chip pw ********       ... login as chip pw ********
        ctrl A                              ctrl A
        lo,p='get fblib'              lo,p='get fblib'
        ... wait until loaded               ... wait until loaded
        go 30000                    go 30000
        Ctrl-\ C                            ... BREAK
                                            ... DISCONNECT
        
        daqstart.com
        
        ... logoff from my and logon again only to start a run on tape
   
    to switch off the FB crate (rarely needed)
        
        on my/onl/run:   suspendevtbld.com
        to continue:     continueevtbld.com
        
   
    REMOTE procedures (if you cannot go to the west hall
        or if you are at DESY)
   
        on my: "connect_CHIMAIN"  or "connect_CHISVX"
   
        also connects to the CHIs, terminate with CTRL \ , then "c"
   
        to press the RESET button by software (careful, once
        the primary CHI is RESET, you cannot reset the secondary
        anymore), (only AFTER suspendevtbld.com !!!):
   
        
        on my: "/us0/wbr/testbeam/chiboot2"  (resets the svx CHI)
               "/us0/wbr/testbeam/chiboot"   (resets the primary CHI)
