month-end closing performance issue
We have met the serious performance issue during month-end closing. It takes more than 48 hours to run CON2 and 30 hour to run CO88. However, there is no any performance issue at the daily system operation. Our basis engineer collects the system information as below:
SAP component version: EHP4 FOR SAP ERP 6.0 / NW7.01
Operation system: AIX
DB version: 09.01.0009
We have only one server for our production system. This server plays both roles as database server and application server.
