我遇到以下异常:
db2jcct2, java.lang.UnsatisfiedLinkError: db2jcct2 (C:\IBM\SQLLIB\BIN\db2jcct2.dll is not a valid Win32 application. ): ERRORCODE=-4472, SQLSTATE=null DSRA0010E: SQL State = null, = -4 472
尝试使用 com.ibm.db2.jcc.DB2XADataSource 作为数据源连接到 DB2，但使用 com.ibm.db2.jcc.DB2Driver 连接正常很好。
com.ibm.db2.jcc.DB2XADataSource 在 WebShpere 8.5.5 上创建
注意
1>was8.5.5 是 64 位 db2 64 位操作系统是 64 位 windows7 - com.ibm.db2.jcc.DB2XADataSource 失败 db2jcct2，java.lang.UnsatisfiedLinkError: db2jcct2 (C:\IBM\SQLLIB\BIN\db2jcct2.dll 不是有效的 Win32 应用程序。):ERRORCODE=-4472，SQLSTATE=null DSRA0010E:SQL State = null，= -4 472
com.ibm.db2.jcc.DB2Driver 也失败了与上面相同的异常。
2> was8.5.5 是 64 位 db2 32 位操作系统是 64 位 windows7 - com.ibm.db2.jcc.DB2Driver 可以工作 –
com.ibm.db2.jcc.DB2XADataSource 失败并显示

最佳答案
这根本不是一个明显的问题；你的 dll 可能没有任何问题。我已经看到了这个问题，并通过切换到类型 4 数据源来修复它。
关于java - 类型 2 驱动程序的 DB2 连接错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23680750/
