which config/parameter is responsible to ICM naming convention

Hi

In my customer's environment.when I request ICM log by the following SQL

SELECT 'ICM_LOG_NAME=' || fcp.logfile_name
FROM apps.fnd_concurrent_processes fcp, apps.fnd_concurrent_queues fcq
WHERE fcp.concurrent_queue_id = fcq.concurrent_queue_id
AND fcp.queue_application_id = fcq.application_id
AND fcq.manager_type = '0'
AND fcp.process_status_code = 'A';

the resuslt is as following

ICM_LOG_NAME=F:\12.1.1\PROD\inst\apps\ACPROD_acoraprod\logs\appl\conc\log\CM_ACPROD_acoraprod.log

generally speaking,the ICM log should shows as the following format.
<SID>_<date>.mgr

Could you please tell me which config/parameter is responsible to ICM naming convention
