Question 4: An end-user indicates that the DRDA client application accessing DB2 for z/OS is very slow.
However, other local applications accessing the same tables are running fine. What would
indicate that this could be a DB2 problem?
A.Calculate the non-nested CLASS 1 CPU time minus non-nested CLASS 2 CPU time. If the value is high,
it suggests a problem in the DDF address space.
B.Investigate the CLASS 3 suspension time. As class 3 time includes the time that DB2 spends
sending/receiving network messages, a high value is a possible indication that the network is
experiencing a slow-down.
C.Calculate the non-nested CLASS 1 Elapsed time (ET) minus non-nested CLASS 2 ET. If the value is
high, this can only be caused by spending most time in the application, and therefore the application
should be investigated.
D.Check to see if the DB2 remote connection can become inactive at commit (Type 2 inactive). If not, this
leads to a high non-nested CLASS 1 ET and is likely the cause of the performance problem. Inactive
connections will use less CPU than threads that stay active all the time.
