探查 JDBC Multipool 问题
| 负载平衡算法 采用负载平衡算法的 MultiPool 以 Round Robin 方式提供其连接，各连接在为其定义的所有 JDBC 连接池之间均匀分布。如果对某个连接的连接测试失败，MultiPool 会尝试从列表中的下一个池中提供连接。以下位置提供了更多详细信息：http://e-docs.bea.com/wls/docs81/jdbc/programming.html#1023962 (English)。 因此，负载平衡既具有在若干个池间分配负载的长处，又能够在其中一个池不可用时提供一定程度的 Failover 能力。不过，如果采用负载平衡算法，将无法控制 MultiPool 响应来自其列表中不同池的连接请求的顺序及其 Failover 的目标池。 MultiPool 的限制 若要为 MultiPool 启用高可用性算法，需要考虑一些限制和前提条件。http://e-docs.bea.com/wls/docs81/jdbc/programming.html#1068130 (English) 中提供了详细信息。下面是对上述要点的总结：

Using Multi Data Sources with Oracle RAC - 11g Release 1 (10.3.6)
Attributes of a Multi Data Source
The multi data source may have the following attributes, depending on the role of Oracle RAC in your system—load balancing or failover:
-
AlgorithmType="Load-Balancing"orAlgorithmType="Failover"With the Load-Balancing option, connection requests are distributed among available data sources; with the High-Availability option, connection requests are served by the first available pool in the list. When a data source becomes defunct, connection requests are served by the next data source in the list.
-
FailoverRequestIfBusy="true"With the Failover algorithm, this attribute enables failover when all connections in a data source are in use.
-
TestFrequencySeconds="120"This attribute controls the frequency at which WebLogic Server checks the health of data sources previously marked as unhealthy to see if connections can be recreated and if the data source can be re-enabled. For more details see Chapter 5, "Configuring JDBC Multi Data Sources."
For fast failover of Oracle RAC nodes, set this value to a smaller interval, for example,
10(seconds).
