识别内存问题,包括较低的缓冲池命中率、较低的目录缓存命中率和较低的包缓存命中率。
Identify problems with memory, including low buffer pool hit ratios, catalog cache hit ratios, and package cache hit ratios.
包与目录缓存,以及工作空间(如包高速缓冲区命中率)。
Package and catalog caches, and workspaces (for example, package cache hit ratio)
可使用下列公式计算包缓存器的命中率。
The package cache hit ratio can be calculated using the following formula.
perl packhitratio . pl dbrun. snap——该脚本提供了包缓存器的命中率。
Dbrun.snap - This script provides the hit ratio for the package cache.
perl packhitratio . pl dbrun. snap——该脚本提供了包缓存器的命中率。
Dbrun.snap - This script provides the hit ratio for the package cache.
