What should service class be for PXNPRC XNET?
DB2 V12 11 & 12 Release 19 & 20.
Its recommend that you assign Xmanager a dispatching priority that is higher than DB2 DBM1, DIST or WLM address spaces, any allied address space such as CICS, IMS, or WebSphere, or any other address space executing SQL. The same considerations apply if you are using WLM in goal mode. However, the Xmanager address space should be assigned to a service class with velocity and importance equal to or higher than the service class assigned to the DB2 system regions and your DB2 applications.This holds true for PXNPRC XNET as well.
