When you configure the workflow to run concurrently with the same instance name, the Integration Service creates logs for each instance. Each log file name includes a run ID and time stamp by default:
<workflow_name>.<runID>.<timestamp>
<session_name>.<run ID>.<timestamp>
For example if the workflow log file name is wf_store_sales.log, and the run ID is 845, the Integration Service creates the following log file names for the binary workflow log file and the text workflow log file if workflow runs on July 12, 2007 at 11:20:45:
wf_store_sales.log.845.20070712112045.bin
wf_store_sales.log.845.20070712112045
When you configure the workflow to run concurrently with the same instance name, and you also define instance names, the Integration Service appends the instance name and the time stamp to the log file name. For example:
<workflow_name>.<instance_name>.<run ID>.20070712112045.bin
<session_name>.<instance_name>.<run ID>.20070712112045.bin
The Integration Service writes the instance name and run ID to the workflow log. For example:
Workflow wf_Stores started with run ID[86034], run instance name[Store1_workflow]
