1. Install glance Pak (the measureware tool included in glance Pak For performance analysis) Check whether glance Pak has been installed. Check the two license files/var/opt/perf/gkey and mwakey. We recommend that you back up these two files, you can avoid the problem that codeword cannot be installed when you reinstall glance. You can directly install the trial version and copy the two original files to overwrite it to the official version. In addition, when you reinstall glance Pak, you need t

as WIO only when the CPU is changed in Aix 4.3.3. When only a small number of threads are performing I/O and other parts of the system are idle, this method can report much lower WIO time. For example, a system with four CPUs and a thread in the I/O process will report a maximum of 25% WIO time. The system with 12 CPUs and a thread in the I/O process only reports the maximum WIO time of 8%. The NFS client reads/writes data through vmm.

Use AWR auto load repository performance reports in Oracle 10g/11g to ensure that snapshots are collected for about 30 days. The interval between snapshots should be 30-60 minutes; then, you can use the dbms_swrf_internal.awr_extract sto
