SOLVED Facing issue while configuring WLSDM

Stuck on Monitoring and Diagnostic screen while configuring

[wlsdmsupport]

Hi,
We analyzed the problem with futher investigation and logs; that realized it is because of getting below error on WebLogic:

Request-URI Too Long

The requested URL's length exceeds the capacity limit for this server.

Cause:
Accesing to WebLogic WLSDM console through a webserver (OHS, Apache… etc.) can cause above error while at the last step on WLSDM wizard screen when clicking on save button.

Solution:
Accessing WebLogic WLSDM wizard console directly (bypassing webserver redirection) will solve the problem. We recommend not to use Webserver proxy while setting up WLSDM wizard at first. After the wizard completion you can use webserver proxy freely.

Webservers have limitations about posting data bacause of security issues. The limit can be increased on the configuration files.

Kind Regards…

Under Apache, the limit is a configurable value, LimitRequestLine. Change this value to something larger than its default of 8190 if you want to support a longer request URI. Extremely long URLs are usually a mistake. If you keep URLs under 2000 characters , they’ll work in virtually any combination of client and server software. URI actually have a character limit depending on several things. Chrome limits url length of 2MB for practical reasons and to avoid causing denial-of-service problems in inter-process communication. On most platforms, Chrome’s omnibox limits URL display to 32kB (kMaxURLDisplayChars ) although a 1kB limit is used on VR platforms. IE - 2083 characters, Firefox - 2047 characters, Safari 80000 characters and Opera 190,000 characters.

To resolve the problem :

• By POST request: Convert query string to json object and sent to API request with POST

• By GET request: Max length of request is depend on sever side as well as client side. Most webserver have limit 8k which is configurable. On the client side the different browser has different limit. The browser IE and Safari limit to 2k, Opera 4k and Firefox 8k. means the max length for the GET request is 8k and min request length is 2k.

If exceed the request max length then the request truncated outside the limit by web server or browser without any warning. Some server truncated request data but the some server reject it because of data lose and they will return with response code 414.
