当我尝试部署一个新的虚拟数据库（Teiid9TestConnection_DS 是数据源名称，用于测试的本地 MySQL 数据源）时，我总是收到以下错误，即使在第一次部署尝试时也是如此：
ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 8) WFLYCTL0013: Operation ("enable") failed - address: ([

我尝试了不同的配置，总是出现这个错误，这不允许我部署 VDB：
- Teiid 设计器 11.0.0 + Teiid 运行时 9.0.6（WildFly AS + Teiid 从 9.0 下载包下载 · Teiid）+ Eclipse 4.6 Neon + Java 1.8。
- Teiid Designer 10.1 + Teiid runtime 9.0.6（WildFly 9.0.6 AS 从 Teiid 单独下载，然后在解压缩时合并）+ Eclipse 4.5 Mars + Java 1.8。
在此主要错误之前，日志还显示Unable to select any database object(s) that match root.
谁能帮我理解和克服这个问题？提前致谢。
