Assign resources (CPU, Memory) to interfaces

Hello Experts,

We are in the process of developing many new interfaces in SAP PI, recently we had an issue that one of interfaces due to change on indexes in Oracle database was running 1 hour instead of usual few seconds and caused a few memory dumps (other interfaces scheduled later started to work parallel). We have a few critical interfaces that has to run and we are looking for some way of assigning resources so "less critical" interfaces won't cause them to run slowly, by taking resources.

Is there any way to assign CPU cores, memory to given Interface/Integration ?

Maybe something like Execution groups in WebSphere Message broker ?

I would be very grateful if someone point me in the right direction.

Best
