这个是Apache DS/conf/server.xml中一段 systemPartition:A very special ContextPartition used to store system information such as users, the system catalog and other administrative information. This partition is fixed at the ou=system context. JdbmPartition:Creates a store based on JDBM B+Trees. JdbmIndex:A Jdbm based index implementation. attributeId:Sets the attribute identifier set at configuration time for this index which may not be the OID but an alias name for the attributeType associated with this Index CacheSize:Sets the size of the index cache in terms of the number of index entries to be cached.
