This property specifies the algorithm that determines how operations are distributed to the data sources attached to a data source pool.
This property can take the following values in addition to the default.
failover
Requests are distributed exclusively to the data source with the highest weight. If that data source fails, requests are distributed exclusively to the data source with the next highest weight.
saturation
Requests are distributed to the data source with the highest weight until the data source approaches its saturation level. Requests are then sent to the data source with the next highest weight .
When the data source with the highest weight drops below its saturation level, Directory Proxy Server resumes sending requests to that data source.
proportional
Requests are distributed to data sources in proportion to the weight of a data source and its cumulative load.
operational-affinity
Requests are allocated a hash value according to the type of the request and the properties of the request. Hash values are allocated to data sources in proportion to the weight of a data source and its cumulative load.
fastest-server
Requests are distributed to the data source with the quickest response time.
adaptive-failover
Requests are distributed to N active data sources with the highest weights so that the sum of the active data sources weights reach the configured processing power value.
This property is used to configure the following features:
ldap-data-source-pool
One or more data sources are attached to a data source pool for load balancing and failover.
