Configuring the cache programmatically

Question

I'm trying to find out if there is a way to configure the cache programmatically. I know that we can configure it via command line parameters (main problem is that this can only be used at VM startup, but we may want to shutdown the cache and start it up again with a different configuration, without restarting the web app or the VM), or via tangosol-coherence-override.xml (main problem is that this is problematic to change in a deployed war/jar, partly because the it would be destroyed/overwritten with a new release of our software). The ideal facility would allow our application to supply Coherence with the XML configuration data, programmatically, at runtime; that is, we would build the XML data ourself (e.g., from our own database that includes configuration data) and pass that to Coherence as a startup parameter. Is there any way to accomplish this kind of programmatic configuration at startup?
Thanks!

Hi Trygve,
You can use {system-property-name default-value} xml-override syntax, for example, you can create tangosol-coherence-override.xml which looks like this:
<code>
<coherence xml-override="{my.override}">
</coherence>
</code>
and then specify an actual file name in your code:
<code>
System.setProperty("my.override", file_name);
</code>
