How can SQL Relay be used with replicated or clustered databases?
If you have replicated or clustered databases, SQL Relay can be configured to maintain connections to some or all of the database servers and distribute sessions over them. SQL Relay can even be configured to maintain more connections to more powerful machines and fewer connections to less powerful machines, enabling a heterogeneous mixture of machines to be used in the database server pool. Note that SQL Relay cannot be used to replicate databases or keep replicated databases synchronized. If you are using SQL Relay to access replicated databases then it is assumed that there is some means by which the databases are kept synchronized external to SQL Relay.
