My customer migrated from a 9672 with OSA/2 to a z9 with OSA Express and DS8000 dasds. Today, I observed that TCPIP consumed constantly about 30% to 40% CPU during three periods of 8 to 20 minutes. The application probabl y is remote access to DB2/VM over TCPIP (surely no FTP, NFS, nor SMTP). I do realize that the new OSA is much faster, so more data can be transfe red per second by TCPIP, but 30% of a z9 engine is much.
Should we consider this as normal, or do we have to start digging? Kris Buelens
