64位tomcat的c3p0

我们有 Sybase 的 c3p0 连接池。它在 32 位服务器上的 Tomcat 7.0 上运行良好。一旦我们在 64 位服务器上运行它，tomcat 和 jre 都安装在 64 位下，它会抛出：

Caused by: com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could not acquire a resource from its primary factory or source.
    at com.mchange.v2.resourcepool.BasicResourcePool.awaitAvailable(BasicResourcePool.java:1319)

    at com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource.getConnection(AbstractPoolBackedDataSource.java:128)

我们已经设置了 64 位系统 DSN。使用指定的 DSN 成功创建数据源。当它在数据源上调用 getConnection() 时抛出错误。

有什么建议吗？

原文

We have c3p0 connection pooling for Sybase. It works fine on Tomcat 7.0 on a 32-bit server. Once we run it on a 64-bit server with tomcat and jre both installed under 64-bit , it throws:

We've set up a 64-bit System DSN. The dataSource is created successfully with the DSN specified. The error was thrown when it calls getConnection() on the dataSource.

Any suggestions?
