[OCI BM LBaaS] How to Increase Request Header Size to 16K in the OCI Load Balancer (Doc ID 2554138.1)

A "414  Request-URI Too Large" error is thrown when trying to access reports through a OCI Load Balancer as a Service (LBaaS).  If the load balancer is bypassed and the Oracle HTTP Server (OHS) hosting the reports is accessed directly, the report is seen.  In the Oracle HTTP Server (OHS) "httpd.conf" configuration file, the parameters "LimitRequestLine" and "LimitRequestFieldSize" are set to 16k.

Even when those parameters are set to 8k in the OHS configuration, going through the load balancer yields the same "414 Request-URI Too Large" error. This confirms that the OCI LBaaS is rejecting the request.  Setting the request header size to 16k in the load balancer should correct the issue.
