[opencms-dev] Fwd: Re: Is there a way to add a new site server without a restart?

[Stephan Hartmann]

Hi Olaitan,

My experience refers to OpenCms 6.2.3. but for 7.x it might be quite the
same.
If you patch the CmsSiteManagerImpl#initialize() to not freeze and not
change the configured maps into unmodifiable maps, you can add new sites at
runtime.
Also, the logic for writing out the changed configuration to
opencms-system.xml is already there, as it is used e.g. when you lock the
workplace or set a login message:

org.opencms.main.OpenCms#writeConfiguration(CmsSystemConfiguration.class);

HTH,
Stephan
