Entry Caching

In Oracle Internet Directory, 10g (9.0.4), the directory server entry cache is supported only in the single directory server instance. The benefits of entry caching are maximized when the entry cache hit ratio is very high. Oracle Corporation recommends that the entry cache be used for small-to-medium-sized directory deployments where:

• The working set of directory entries can be completely cached

• The concurrency of clients can be handled by a single directory server instance

Internal benchmarks indicate that, for directory deployments where the working set of entries is a few hundred thousand entries, the entry cache doubled the throughput of operations for up to 1000 concurrent clients.

For directory deployments with a larger working set of directory entries and a higher concurrency of clients, it is using the multiprocess directory server instance and the Oracle buffer cache results in greater scalability.
