w3ServerPool is a synonym for (and has replaced) w3HostName. In this document, all w3HostName references have been changed to w3ServerPool.
A server pool is the naming and grouping of one or more FlashCONNECT connections spanning one or more database servers that are connected to one or more Web servers. FlashCONNECT allows one or more database servers to connect to one or more FlashCONNECT enabled Web servers. Server pools are optional, but there must be a default server pool defined to access the online manual.
Server pools enable the distribution of an application across several systems.
The system administrator specifies which server pool a system supports using the WWW-START command.
The programmer specifies which server pool should be used to service a request by setting the w3ServerPool variable.
Ensure that the server pool name is not an attribute-defining item (ADI) or data level in the w3lines file or the ADI will be overwritten by the server pool state.
FlashCONNECT assigns the connection to any database server that supports the requested server pool. If no server pool is chosen, the default server pool is used.
Server pools also allow load balancing and tighter control of resource allocation. For more information about server pools, see the FlashCONNECT Administrator’s Guide.
Server Pool names are case sensitive. FlashCONNECT maintains the original casing of the server pool name as entered in the w3config file. The FlashCONNECT server pool name can be a maximum of 14 alphanumeric characters and must include at least one letter in the name.
