TOP TEN: Most viewed KBA for General Performance in August
A useful bridge KBA that takes your step by step how to troubleshoot High RFC time in ST03n. Although the root cause is often difficult to locate, this KBA will most definitely assist.
- Network performance issues
The result of communication and high data volume issues
- Slow running jobs between different SAP systems (for example ERP and BW)
Indicated by high roll wait time in the ST03 monitor.
In this scenario a job that is running between SAP systems can take a long time to complete on the target system.
This can be an application, hardware or database specific issue.
- Unavailable RFC resources
Individual RFC resources are overutilized on the target system which can generate high wait time.
- A misreported response time which is not related to an actual performance issue, but is bug related in manner.
In this case the response time will be unrealistically high.
