Error -27740: Overlapped transmission of request to "www.url.com" for URL "http://www.url.com/ProdApp/" failed: WSA_IO_PENDING

 

What is WSA_IO_PENDING? WSA_IO_PENDING 997, is a Windows Socket error that is returned by the WSAGetLastError function. It is non-LoadRunner error like "Error -27728: Step download timeout (999 seconds) has expired when downloading non-resource(s)" or "Connection to load generator failed. Error: Process "lr_bridge.exe" was not created. Reason: - communication error. [MsgId: MERR-29996]", etc. The error means the overlapped operations will complete later. From Windows Socket perspective, the application has initiated an overlapped operation that cannot be completed immediately.

The NoClassDefFoundError for Java-RMI protocol. There are several possibilities that this error occur such as (a) incomplete configuration of the Java environment requirements (refer to "Working with RMI-Java"), (b) incomplete reference to the Java libraries (usually located in {loadrunner-installation}\classes and {loadrunner-installation}\classes\srv after the required copy of the application's Java classes are placed in them) and (c) incorrect -Xbootclasspath to inform VUgen to point to the Java libraries for recording.

The error message that is thrown upon when the bootclasspath was not specified in the recording options is shown below:

Background information: I'm monitoring 4 WebLogic servers using WebLogic (JMX) Monitor in LoadRunner and adding their JMX stats into Controller. Upon adding the subsequent server, the error appeared after entering the username and password to the Controller. I'm using LoadRunner 9.0 and Weblogic 8.1 in this context.
