由于 jdbc preparedstatement execute WCS，WAS 挂起 WSVR0605W
WAS gets hung WSVR0605W due to jdbc preparedstatement execute WCS
我正在尝试在一个函数内执行三个不同的准备语句，该函数基本上在三个不同的表中执行插入操作。

createConnection 方法 - 我正在使用 ojdbc6.jar
private Connection createConnection() throws SQLException, Exception

当我从本地 RAD 或本地环境中的网页调用 regPoints 函数时，它工作得很好。但是当它在测试环境中为 运行 时，同样不起作用。当我检查日志时，我可以在 SystemOut.log 中看到以下警告，并且我也检查了数据库。它从不插入任何数据，因为初始插入是它挂起的地方

这与jdbc版本有关吗？或者我们对此问题有任何具体原因吗？
下次，当您想知道 JDBC 版本时，只需执行“java -jar ojdbc8.jar”。另外，按照建议，最好使用最新的驱动程序。如果你至少有 JDK8，那么即使你的数据库是 12c，你也可以使用 19.7。您可以从 [Central Maven] or can download them from here.
获得 JDBC 个驱动程序
➜ lib **java -jar ojdbc8.jar**

我设法从连接池中获取连接而不是创建连接以避免上述问题。默认情况下，WCS 不允许使用 serverjdbchelperaccessbean 执行批处理语句。所以我从 basejdbchelper class 获取了数据源并获得了连接。
DataSource ds = BaseJDBCHelper.getDataSource();
Connection dbConn = ds.getConnection();

这与jdbc版本有关吗？或者我们对此问题有任何具体原因吗？
下次，当您想知道 JDBC 版本时，只需执行“java -jar ojdbc8.jar”。另外，按照建议，最好使用最新的驱动程序。如果你至少有 JDK8，那么即使你的数据库是 12c，你也可以使用 19.7。您可以从 [Central Maven] or can download them from here.
获得 JDBC 个驱动程序➜ lib **java -jar ojdbc8.jar**
Oracle 19.7.0.0.0 JDBC 4.2 compiled with javac 1.8.0_241 on Tue_Feb_11_04:20:00_PST_2020

我设法从连接池中获取连接而不是创建连接以避免上述问题。默认情况下，WCS 不允许使用 serverjdbchelperaccessbean 执行批处理语句。所以我从 basejdbchelper class 获取了数据源并获得了连接。
DataSource ds = BaseJDBCHelper.getDataSource();
Connection dbConn = ds.getConnection();
