I found the "mental ray bump" and inserted a pic using hte "file" maya node.
I uped the Alpha gain value but saw no result...

Use mia_material_x or _passes instead.

can you add details about the workflow (especialy the bump part) ? what are the steps

there is no workflow really, just pick an mia_material_x as mentioned scroll down to the bumps tab you will find 2 slots an overall bump and a standart bump just plug the file into one of them.

I've done a lot of research on this for my current animation project. I would recommend using mia_material_x which supports bump by default. Just drag and drop your texture over your mia_material_x and choose standard bump. It will create a bump map and you can adjust the depth there.

With mia_material (the older shader) I had to use misss_normal to get the same thing done.

If you wish to use mia_roundcorners to have some objects appear a little more natural in your scene, plug that into overall bump.

if you already have your material looking good but just want to add bump to a normal mia_material (for example). scroll down the the bottom of the materials attribute editor and find upgrade shader. here you need to upgrade the shader to an mia_material_x that supports bump. a bump drop down menu will appear in the attribute editor for the material and you can plug a bump or normal map into the standard bump node, the overal bump node can be used for plugin in the mia_roundcorner node to add bevel any object which has th material applied to.
