DC mean test

Test Objectives

Check for potential memory corruption in datacondAPI by monitoring the mean value of the ADC data for a channel H1:LSC-AS_Q.

APIs affected by this test

All APIs are exercised via a dataPipeline command.

Setup

ligotools package is required for running this test. Check that it is mounted

Install the following tests script in a directory on the ldas system
- onejob.tcl - driver scrpt to submit condition data job

S2 raw frame files or S2 RDS L1 data must be mounted on ldas system and known to diskcacheAPI:


        dc mean test is usually run as part of the dataPipeline Loops
        where there is built in checking for
        the memory value. The test passes if the value is within the expexcted limits.
        
        
Test Execution

		cd <your scripts directory>

		
        Usage: onejob.tcl [options] -f dcmean.rds >& dcmean.log & 

        

            
                Option
                Description
			

                <-s>
                ldas site e.g. dev, lho, ldas-suntest3
        
e.g.

            onejob.tcl -s dev -f dcmean.rds >& dcmean.log &
            onejob.tcl -s dev -f dcmean.cmd >& dcmean.log &
        
		
		
Test Validation:
        
        The conditionData job should complete successfully. 

        
The result ilwd from the dataPipeline has the mean value for 
        Adc Data of channel H1:LSC-AS_Q
        
        e.g. 
        
            
                -2.2270608572370154e-03
        
        
        If this value is -2.2270608572370152e-03, the test passes.
