A cache system stores a number of different datasets. The cache system includes a number of cache units, each in a state associated with one of the datasets. In response to determining that a hit ratio of a cache unit drops below a threshold, the state of the cache unit is changed and...
If the current hit ratio is below the target for the plan cache and no other storage constraints exist, the system will automatically increase (up to the Maximum Plan Cache Size for Auto-sizing) the size of the plan cache. The plan cache will grow incrementally, allowing more plans to be...

In general, accessing data through a cache hit is faster than through a cache miss. Thebuffer cache hit ratio measures how often the database found a requested block in the buffer cache without needing to read it from disk. The database can perform physical reads from either a data file ...
In such cases, the byte hit ratio trade-off is complicated by the fact that aggressive cache prefetching also requires aggressive cache eviction. Eviction of prefix segments may adversely affect playout latency for future requests, whereas over dedication of resources to prefixes may result in play...
Calculates the overall hitrate, that is right from the start of the liveCache until now and gives you the ratio in percent. And as I could see on your system in the transaction /nLC10 ->liveCache:Monitoring -> Current Status -> Memory Areas -> Caches : for the catalog cache ...

4. The method of claim 1 wherein: the method further comprises incrementing, during a hit in the cache, a cache hit counter; the adjusting is further based on the cache hit counter. 5. The method of claim 4 wherein the adjusting is further based on at least one of: a ratio of the...
12A, process 1200 may include analyzing a cache hit ratio for each IP address in the watch list (block 1215), and adding an IP address to an intercept list when the cache hit ratio of the IP address exceeds the threshold (block 1220). For example, in an implementation described above ...
