Many of the LoadRunner users with Oracle NCA will face this error in their daily usage.Lets take a look at this error and concept behind it and how to resolve this.
Concept:
When the client send a request to Server,in general it process that request immediately.But in case or Oracle NCA it takes more time to process the requests and meanwhile client is waiting to receive the response.to maintain the handshake during this time, Server send messages to the client that starts with IfError#00 saying the time to process your request takes some time and maintain handshake meanwhile.
But The client waits certain period of time to receive the response, if not it will fail to proceed further and throws the error message ifError during the replay of the script.
Solution:
Go to Oracle NCA protocol, under Runtimesettings->OracleNCA->Client Emulation, there you will see a mode called Pragma mode ”
Oracle NCA recording can be in Two modes : normal recording with Oracle NCA and web(http/Html) and second mode is Pragma mode.
to record the script in pragma mode, please read the Vugen user guide to tune the settings in recoding options.
UseHttpConnect mode should be 1 Servlet mode is set to 2.
Find the options :
1.Max retries
2.Retry interval (ms)
Increase these two values to the avoid the ifError expires message.
let me know if you need any other assistance in solving this issue
