STOPSAP Problems on DoubleStack Systems

Hello together,

for a long time we have problems during the shutdown of double stack systems.

We stop our DoubleStack systems with the following command as <SID>OFR or <SID>ADM:

STOPSAP SID('<sid>') INSTANCE(*ALL)

Now the main instance DVEBMGS<nn> is stopped. But the SCS is still running.

Only a STOPSAP command especially for the SCS helps to shutdown the SCS:

STOPSAP SID('<sid>') INSTANCE(<numer of SCS>)

We are running sap on IBM i V7R1 with a Kernel version 7.20.

The problem ocurrs on different systems with different versions of Kernel 7.20.

Maybe someone knows the problem and can help us.

Thanks in advance.

Tobias
