HTTP-sessions without user or application - How to find basic cause? (Discussion)

294 Views

Hi community,

for some weeks I/ we follow a kind of strange behaviour and couldn´t figure out the basic cause for this until now. Maybe you can share your ideas or have had a similar case and could solve it.

On a Netweaver 7.4 / EHP7 FOR SAP ERP 6.0 System (ABAP) we see observe entries with no "User Name" and no "Application" information. All of this entries have client 000, session type "HTTP", priority "Medium" and memory 111. Logon location is the same for all of them too, it´s the address of one of our SAP Web Dispatcher instances.

The number of this entries varies over the day. Normally the sessions vanish after around three hours. It seems like something is causing bursts of this sessions sometimes. Unfortunately the reason for this bursts is not clear until now too.

The system mostly runs a bunch of ABAP reports and ITS Services our developers made. Because of this the cause might be somewhere there, maybe with in connection with some functions Netweaver offers.

Enable tracing has not brought up any useful information until now. If there might have been anything useful in the trace files it was well hidden between other information. The Problem is that we don´t know the source so we can not reproduce this logon´s/ session´s.

Do you have any idea how we can track down the reason for this to find a solution?
