I created a proc and in the source command I have taken the filename. there can be around 500 file names. In the target command I used below command.
OdiStartScen "-SCEN_NAME=LOAD_JSON_FILE_PARALLEL" "-SCEN_VERSION=001" "-LOG_LEVEL=6" "-SYNC_MODE=2" "V_INSTANCE_ID=V_INSTANCE_ID" "V_FILE_NAME=#FILE_NAME" "V_SESSION_NO=V_SESSION_NO"

When I execute this, I can see this executes 500 sessions. But this triggers only 5 sessions at a time. I have not seen this configuration in ODI. Can someone please help me how I can increase this from 5 to 500. Attached is the screenshot
