► DB2 Network Stats ABAP report (see Figure 5-16) This report shows network statistic information for a defined time frame, but requires the collection to be enabled. Some of the data can also be aggregated to obtain an overview. Among other information, the number of round trips, round-trip time and server time, and data transfer is shown for an interval. Figure 5-16 Network statistics (aggregate) For example, in the ITSO lab environment (see Figure 4-13 on page 76), application server p5503p2 has a performance problem. The system response is slow. Because the hardware setup is identical between both AIX systems in the lab environment, it might be a network issue. We use the DB2 Network Stats report (Figure 5-16) to analyze the network performance and compare the ratio of all application servers, by using the equation: (roundtrip time – server time)/roundtrips This equation gives of the ratios for the following servers: ► lnxsu11: 167.71 (microsecond / roundtrip) ► aixsu11: 298.28 (microsecond / roundtrip) ► p5503p2: 968.18 (microsecond / roundtrip) The value of server p5503p2 is high compared to the other servers. Therefore, the performance problem of this server seems to be network-related. Looking at the network configuration shown in Figure 5-17 on page 97, it is clear that the performance problem is based on the slow network connection. 96 Running SAP Solutions with IBM DB2 10 for z/OS on the IBM zEnterprise System

The performance toolkit monitors z/VM and z/VM users, among other things. Configuring z/VM monitoring We used the default configuration of the Performance Toolkit. The configuration file is FCONX $PROFILE. We completed the following steps: 1. Log on to z/VM as user perfsvm. 2. Define the monitoring by using the monitor control program (CP) command. Chapter 5.
