Avoid HTTP server down time for certificate renewal

With the looming prospect of certificate renewal every 47 days after 15 March 2029 in mind, it will become a burden if this requires an HTTP to be restarted.
This is about adding functionality to "refresh" a certificate when it is being renewed, to prevent down time. Especially since the use of IBM webservices servers has grown on IBM i.
As there are a lot of IBM i LPARS out there, who do not IPL within the 47 days windows, this will be undesired side effect of adding more security to certificates.

No idea if this is even possible, but my mother told me: if you do not ask the question, you are sure you do not get an answer.

    Thanks for your feedback. This idea was based on the IBM support case mentioned when creating this idea. After asking IBM support for a confirmation, that this functionality already existed, they confirmed thsi.

    For that reason please disregard this idea.

    This function already exist and have been available for long time for the Apache HTTP server, however for some reason the function is not called refresh or reload, it is called restart and the name is somewhat misleading.


    The easiest way to use this, after a new certificate have been assigned in the DCM, is from the IBM HTTP Web Admin GUI. Select an active http server from the HTTP Servers tab and then choose the Restart button between the Start and Stop buttons.

    You should be able to use commands as well, but for me the command has not always worked, the new certificate have not been loaded, so sometimes, I had to fall back to the HTTP Web Admin GUI and do it again from there.
    STRTCPSVR SERVER(*HTTP) RESTART(*HTTP) HTTPSVR(<HTTP_Server_Instance>).

    Liberty based Application servers and Integrated Web Service server should be able to pick up the new certificate instantly without ending/starting the service when the certificate have been assigned, either with the HTTP Web admin GUI or the Navigator.

    Sadly, the IBM ADMIN* servers do not pickup the certificate, at least not all of them, but most likely the ADMIN* servers can be restarted without impact of the users applications.

    I have previously made a comment about this in the following IBM idea: https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-4563
