Please forgive what is probably a "newbie" question

The first of my OES2 servers is about to have its SSL certificates expire.

I've done the following:

- issued new certs via iManager
- namconfig -k
- namconfig restart

Here's where I get stuck..... what else do I need to do to ensure that all services are using the new certificates eg Tomcat/Apache/etc - on NetWare I simply used tckeygen and restarted these services!

I've done a google on this topic and don't find to find any single conclusive document (perhaps I need new glasses). I would appreciate it very much if the community could point me in the right direction.

Thanks in advance
