Question

我正在使用IBM DB2 for LUW v10.5。 webapi（ASP.NET应用程序）是IIS上托管的应用程序的名称。调用webapi方法时遇到以下错误。

有关SQL1159N的详细说明，请参见以下URL：

SQL1159N用于.NET的IBM数据服务器提供程序初始化期间发生错误。原因码：原因码。
https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.5.0/com.ibm.db2.luw.messages.sql.doc/com.ibm.db2.luw.messages.sql.doc-gentopic5.html#sql1159n

这是说明的片段：

您可以使用.Net的IBM数据服务器提供程序访问IBM数据库系统。

数据库产品安装出现问题时，将返回此消息。当启用Windows扩展安全性功能并且用于启动Internet信息系统（IIS）服务的ID不属于DB2ADMNS组或DB2USERS组时，也可以返回此消息。

此消息的原因码仅适用于IBM支持人员。

希望这会有所帮助。
