When the weighted least connection routing algorithm is chosen, the active connection count to weight ratio is computed for each managed server. The server with the lowest ratio is selected and if multiple servers have the same value, one among them is selected randomly. Due to this random nature of selecting servers, slight deviations occur which is more pronounced in the case of a small number of requests. But as the number of requests increases, we expect it to level out and make the distribution more even.

In the WebServer Logs, errors similar to the following example are observed.

Error reading POST data from client - Total length of data currently processed is : 1073741824
. . .
IO error reading client POST data;
. . .

Workaround

As per the Apache specifications, by default the LimitRequestBody value is considered as 1073741824 bytes. In order to allow a large request size, you need to use higher values. You can use 0 to allow unlimited data. However, using 0 is not recommended.

For more information, see Apache Core Features.

An error message is displayed during Upgrade Assistant Readiness check if the current version is not supported for a direct upgrade to the 14.1.2.0.0 version.

Workaround

The only supported starting point for upgrade to 14.1.2.0.0 is 12.2.1.4.0. You must first perform an upgrade to the 12.2.1.4.0 version and then try to upgrade to the 14.1.2.0.0 version.

In Oracle HTTP Server 14c, for each SSL enabled Virtual Host an export_wallet program is called to export content of the wallet configured for that Virtual Host. This is true for both SSLWallet and SSLProxyWallet that mod ossl handles. In a configuration that has 100 Virtual Hosts, the export_wallet program is called 100 times before OHS can startup which results in the Oracle HTTP Server slow startup.
