三台ColdFusion服务器中仅一台Snowflake JDBC数据源无法工作

问题描述 #

两台ColdFusion服务器上的Snowflake JDBC数据源配置正常且可执行查询，但第三台配置相似的服务器上相同配置无法工作，提交数据源详情时返回错误：

Connection verification failed for data source: snowflake_jdbc
java.sql.SQLException: null.

该数据源曾短暂可用一个下午，无任何修改的情况下突然失效。

环境信息 #

• Windows Server 2019 Datacenter
• ColdFusion 2021 Update 12
• Snowflake JDBC驱动 3.14.4（也曾尝试回滚至3.13.32）
• Java JDK 11.0.21（64位）

数据源配置（ColdFusion管理页面） #

• JDBC URL: jdbc:snowflake://*ACCOUNT-IDENTIFIER*.snowflakecomputing.com/?JDBC_QUERY_RESULT_FORMAT=json
• 驱动类: net.snowflake.client.jdbc.SnowflakeDriver
• 用户名: *USERNAME*
• 密码: *PASSWORD*

已尝试的操作 #

• 删除并重建数据源
• 删除替换JDBC驱动文件
• 将驱动版本从3.14.4回滚至3.13.32
• 每次修改后均重启ColdFusion 2021 Application Server服务
