Ignite Configuration file modify

[kay <go...@gmail.com>]

Hello, 
Is there a way to modify the configuration file after Ignite Node starts?
Should I use FTP directly to create a page to modify configuration file?

I know I can add cache in ignite run time but after restart, There is not
exist cache add in runtime.
So I need to find a way modify configuration file..

Thank you so much

Ok, well modifying the configuration might not be a good solution, what 
if you have multiple nodes and the configurations files no longer match, 
I guess you could create a service that runs on all nodes and have that 
updating the XML configuration files when you add caches, there is no 
need to "reload" the configuration while Ignite is running as you create 
the caches manually from code AND update the XML configuration, and on a 
restart the caches will be in the modified configuration.

Any chance you could enable persistence on the system cache ? that would 
keep your created caches on restart.

The reason you cannot reload configuration while running is that many 
settings cannot be changed on a running instance, page size, off heap 
memory region sizes and so on.

Hello!

You can implement this yourself if you really need it.

Such as, you can watch an XML file, when it changes, do
Ignition.loadSpringBin(file, bean name), and then call
ignite.getOrCreateCache() on all cache configurations found in that bean.

Regards.

Hello :)

Because If I add cache by code, the cache disappears when the node is
restarted 
so I want to modify the configuration file directly.

Thank you!

Hi!

No, you need to restart Ignite if you change xml configuration as far as 
I know.

But you can add caches after Ignite is started without any problems, 
both from code and from SQL, is there any reason you cannot use one of 
these methods ?
