After upgrading and attempting to set maxMessageBodySize via iControl REST, you get an error indicating the command is not implemented: {"code":400,"message":"onPut Not implemented","originalRequestBody":"{\"maxMessageBodySize\": \"111111111\"}","referer":"","restOperationId":216941,"kind":":resterrorresponse"}


Command fails, unable to set maxMessageBodySize.


This occurs when upgrading from v11.6.1 to v12.1.0, v12.1.1,or v12.1.2, and applying the UCS from the 11.6.1 release. The error is generated because new defaults were added but they are not set on UCS restore.


If you encounter this after an upgrade and UCS restore, you can run the following commands from the BIG-IP command line: 1. curl -X DELETE http://localhost:8100/shared/storage?key=shared/server/messaging/settings/8100. 2. bigstart restart restjavad.

Fix Information

You can now set maxMessageBodySize via iControl REST after upgrading.
