我正在AS400服务器上运行的Java应用程序上工作。
try {
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
String doTrace = AppProp.getInstance().getProperty("trace.enabled");
if("true".equals(doTrace)){
Trace.setTraceAllOn(true);
String tracefile = AppProp.getInstance().getProperty("trace.file");
new File(tracefile).createNewFile();
Trace.setFileName(tracefile);
Trace.setTraceOn(true);
log.warn("Trace Enabled");
}
} catch (Exception e) {
log.error(e.getMessage(), e);
throw new ExceptionInInitializerError(e);
}
还有这个
try {
if ("true".equals(local)) {
user = "*CURRENT";
password = "*CURRENT";
}
connection = DriverManager.getConnection(url, user, password);
} finally{
//do something here...
}
使用url beeing jdbc：as400：//10.65.1.31/QSYS.LIB
在连接到AS400的Windows服务器上运行时，我工作正常，但是在AS400上本地运行时，出现异常：

从跟踪日志中，我现在发现了这一点：

您知道可能是什么问题吗？
我们在AS400版本R610上运行
由于某种原因，程序试图使用Kerberos验证用户-即使我提供了参数AuthenticationMethod = client
现在，我试图启动和运行一些远程调试，因此我们将CL命令修改为：
RUNJVA CLASS('com.df.info2000.wscom.MainExtract')
CLASSPATH('/DFWSCOM/config/')
OPTIMIZE(*JIT) INTERPRET(*JIT)
PROP(
(os400.xrun.option 'jdwp:transport=dt_socket,address=8000,
server=y,suspend=y')
(java.security.krb5.conf
'/QIBM/ProdData/OS400/NetworkAuthentication/krb5.conf')
(java.ext.dirs
'/DFWSCOM/lib/')) GCHINL(240000000)
GCHMAX(*NOMAX) JOB(WSCOVFC) OUTPUT(*NONE)
但这以以下消息结尾：
信息 。 。 。 。 ：* SRVPGM的JVM_OnLoad处理期间发生错误
JDWP15。错误代码是3。
Årsag。 。 。 。 。 ：* SRVPGM的JVM_OnLoad函数未完成
JDWP15由于出现错误代码3。错误代码定义如下：1-
JVM无法找到服务程序。 2-JVM无法执行
激活服务程序。 3-JVM无法找到
JVM_OnLoad函数。 4-从JVM_OnLoad返回错误代码0
我的AS400员工说它不了解os400.xrun.option-有人能看到我们在做什么吗？
好吧-现在我们将程序移至产品环境中，看看它是否可以在此处运行-神奇地它将在那里运行，因此我们的测试AS400出了点问题。所以现在它可以在产品中使用，并且我们可以在测试服务器上解决这个问题。
最佳答案
其实我不知道您到目前为止已经尝试了什么，但是只需遵循以下代码并验证自己即可解决... !!!
Connection con = null;
try {
Class.forName("com.ibm.as400.access.AS400JDBCDriver);
} catch(ClassNotFoundException e) {
System.out.println(e);
System.exit(0);
}
try {
con = DriverManager.getConnection("jdbc:as400://yourserver", "yourUserId", "yourPassword");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM YOURLIB.YOUR_PF_FILE");
while (rs.next()) {
String field1 = rs.getString(1);
String field2 = rs.getString("fieldname");
.....
} catch(Exception e) {
.....
}
我希望这能帮到您
