CODA Summary

Mott DAQ iocmdaq1

There are two ways to access the Mott DAQ ioc: 

1. From an accelerator machine: telnet iocmdaq1
2. From an accelerator machine: ioc_concole iocmdaq1. Here you need to enter a password to this cannot be done with the idaq account.

The startup file: idaq@opsmdaq0:/cs/op/iocs/iocmdaq1/startup

The CODA boot file: idaq@opsmdaq0:/opt/coda/boot/mott_roc1.boot

cefdmp/xcefdmp

The event dump utility (cefdmp) can display, in a readable ASCII format, events from the data files.

Syntax

% cefdmp [filename] [-o object] [-t tag] [-u uniquetag] [-s start] [-e end] [-d dictionary] [-x] 
% xcefdmp [same] 

Options

o specify the source object name (CODA component name) 
t select specified tag number or name (full path in event structure) 
u select specified unique tag, independent of location in the event 
s number of first record in file to dump 
e number of last record in file to dump 
d specify dictionary for obtaining tag names and titles 
x hex dump of integers (default is decimal) 

cedit and dbedit

Use cedit and/or dbedit to modify CODA database.

Issues and FAQ

• RunNumber: if the in the msql is different from the one in cool database, coda doesn't work. To solve it open dbedit => localhost => sessions and change the RunNumber
