我正在使用 JDBC 连接到 DB2 并执行 SQL 语句。运行一个简单的:
SELECT * FROM myview
我得到一个:
State : 24501
Message: [SQL0501] Cursor CRSR0001 not open. Cause . . . . . : The cursor CRSR0001 was specified in a FETCH or CLOSE statement, but the cursor is not open. Cursor CRSR0001 has one of the following conditions: -- Cursor CRSR0001 was never opened. -- The cursor CRSR0001 was opened in another program or another call of this program and the program was created with CLOSQLCSR(*ENDPGM). -- The cursor CRSR0001 was opened in another module or another call of this module and the module was created with CLOSQLCSR(*ENDMOD). -- The cursor CRSR0001 was opened in another call of this program and programs which have run SQL statements have ended and the program was created with CLOSQLCSR(*ENDSQL). -- The cursor CRSR0001 was opened in another call of this module and the activation group ended between calls. The module was created with CLOSQLCSR(*ENDACTGRP). -- The cursor was closed by a CLOSE, COMMIT, or ROLLBACK statement. -- The cursor CRSR0001 was opened under a transaction which is different than the current transaction. Recovery . . . : Do one of the following and precompile again: -- Make certain that cursor CRSR0001 is opened in the same program or module call prior to using the cursor in an FETCH or CLOSE statement. -- Specify either CLOSQLCSR(*ENDSQL), CLOSQLCSR(*ENDJOB), or CLOSQLCSR(*ENDACTGRP) when precompiling the application. -- If the cursor was closed by a COMMIT or ROLLBACK, specify HOLD on the COMMIT or ROLLBACK statement to preserve any open cursors, prepared statements, and locks on tables.
Error : -501
当我调用时从结果集中获取最后一行后，就会发生这种情况
rs.next()
如果我向 select 语句添加一个 where 子句，它可能会也可能不会出现相同的错误(取决于我要过滤的内容)。但似乎与任何特定行无关。
我已经能够通过以下方式规避这个问题: * 将连接字符串中的“ block 大小”参数更改为 2 的任意幂，32(默认值)除外
或者通过更改语句的初始创建方式:
// Get a statement from the connection
stmt = conn.createStatement(); // doesn't work
stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY); // doesn't work
stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE); // works
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE, ResultSet.CLOSE_CURSORS_AT_COMMIT); // works
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE, ResultSet.HOLD_CURSORS_OVER_COMMIT); // works
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY); // works
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); // works
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE); // works
stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY, ResultSet.CLOSE_CURSORS_AT_COMMIT); // doesn't work
stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY, ResultSet.HOLD_CURSORS_OVER_COMMIT); // doesn't work
我测试了 JT Open 的各种 JDBC 版本(6.4、6.6、7.4)。所有这些都显示相同的问题，因此这可能不是驱动程序问题。
此外，最奇怪的部分可能是，如果我使用相同的底层 SQL 创建另一个 View (不同的名称)，那么它每次都能正常工作。删除旧 View 并重新创建它并不能解决问题。
最后，AS400 机器最近已修补(大约是我们开始注意到问题的时间)。这段代码之前已经运行良好很长时间了。
有什么想法吗？
PS。代码:Driver d = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(d);
conn = DriverManager.getConnection("jdbc:as400://1.1.1.1/MYLIB;prompt=false;keep alive=true;errors=full", "user", "pass");
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
while (rs.next()) {
System.out.println(rs.getString(1));
}
PS:跟踪的输出:

最佳答案
我建议运行跟踪以获取更多信息。
请参阅 IBM 软件技术文档:The All-In-One Toolbox Tracing Guide。
<小时/>另请检查连接作业日志中的诊断消息。您可以从跟踪中或使用连接对象上的 getServerJobIdentifier() 方法获取作业编号、用户和名称。
String serverJobIdentifier =
((AS400JDBCConnection)conn).getServerJobIdentifier();
一些可能有用的附加信息:
- 这是本地运行还是远程运行？
- 您使用的是哪种 JVM？
- 您检查过精液和群体 PTF 水平吗？
- 您可以包含
WRKPTFGRP命令的输出吗？
