Am using EP 7.01EP8. Am new for the Portal.In Production PortalActivityTrace is not updating properly for the past two weeks. Before that it updates properly. I did stop/restart the services activitydatacollector and activityreport.core. and restart the system and did many events like open the reports,iviews etc. The new file itself not created in the path /usr/sap/OPP/JC02/j2ee/cluster/server0/portalActivityTraces. Help me to solve the issue.
