Application process are not killeg after DB crash

Hi all,

We have Oracle 11g RAC with 3 DB nodes and 4 SAP Application servers. One node crashed due to network issue. The sessions are then relocated to other node due to high availability of oracle. After the node came up. We can see many application sessions which were running on the node. It is not automatically killed. I went through alert log of SAP instances. But still no luck. Kindly suggest on it.

Regards,
