Load the session statistics such as Session Start & End Time, Success Rows, Failed Rows and Rejected Rows etc. into a database table for audit/log purpose.

Scenario:

Load the session statistics such as Session Start & End Time, Success Rows, Failed Rows and Rejected Rows etc. into a database table for audit/log purpose.

Solution:


After performing the below solution steps your end workflow will look as follows: 

START => SESSION1 => ASSIGNMENT TASK => SESSION2

SOLUTION STEPS

SESSION1 
This session is used to achieve your actual business logic. Meaning this session will perform your actual data load. It can be anything File Table.àFile or TableàTable, File à 

WORKFLOW VARIABLES 

Create the following workflow variables. 

=> $$Workflowname 
=> $$SessionStartTime 
=> $$SessionEndTime 
=> $$TargetSuccessrows 
=> $$TargetFailedRows 


ASSIGNMENT TASK 

Use the Expression tab in the Assignment Task and assign as follows: 

$$workflowname = $PMWorkflowName 
$$sessionStartTime = $ SESSION1.StartTime 
$$SessionEndTime = $ SESSION1.Endtime 
$$ TargetSuccessrows = $ SESSION1. TgtSuccessRows 
$$ TargetFailedRows = $ SESSION1. TgtFailedRows 

SESSION2 

This session is used to load the session statistics into a database table. 
=> This should call a mapping say ‘m_sessionLog’ 
=> This mapping m_sessionLog should have mapping variables for the above defined workflow variables such as $$wfname, $$Stime, $$Etime, $$TSRows and $$TFRows. 
=> This mapping m_sessionLog should use a dummy source and it must have a expression transformation and a target => database Audit table) 
=> Inside the expression you must assign the mapping variables to the output ports 
workflowname=$$wfname 
starttime=$$Stime 
endtime=$$Etime 
SucessRows=$$TSRows 
FailedRows=$$TFRows 
=> Create a target database table with the following columns 
Workflowname, start time, end time, success rows and failed rows. 
=> Connect all the required output ports to the target which is nothing but your audit table. 

PRE-Session Variable 

=> Session 2: In the Pre-session variable assignment tab assign the mapping variable = workflow variable 
=> In our case 
$$wfname=$$workflowname 
$$Stime=$$sessionStartTime 
$$Etime=$$sessionEndTime 
$$TSRows=$$TargetSuccessrows 
$$TFRows=$$TargetFailedrows
