Variables in config Files

JensAernouts

Hello,

I have the following configuration file what I use multiple times in my application:

TopicManager.Proxy=TestIceStorm/TopicManager:default -p 40001 -h 192.168.2.2
OSLInterface.Proxy=TestInterface/Query:default -p 40003

CalculatorAdapter.AdapterId = CalculatorAdapter
CalculatorAdapter.Endpoints = tcp -h 192.168.2.2 -p 10000
Identity = Calculator

Ice.Default.Locator = IceGrid/Locator:tcp -h 127.0.0.1 -p 4061
Ice.MessageSizeMax = 32768

I'd like to know if it's possible to change the ip address '192.168.2.2' by a variable, for example 'TestIP' so that I only have to change this IP once. My config file should look like this then:

TestIP = 192.168.2.2
TopicManager.Proxy=TestIceStorm/TopicManager:default -p 40001 -h TestIP
OSLInterface.Proxy=TestInterface/Query:default -p 40003

CalculatorAdapter.AdapterId = CalculatorAdapter
CalculatorAdapter.Endpoints = tcp -h TestIP -p 10000
Identity = Calculator

Ice.Default.Locator = IceGrid/Locator:tcp -h 127.0.0.1 -p 4061
Ice.MessageSizeMax = 32768

Kind regards

Hi Jens,

There is no such thing as a "variable" with Ice configuration files. There are however other options you may want to consider:

- since you're using IceGrid, and this is the configuration for a server, you should write a 'server descriptor' and let IceGrid generate this configuration file for you. You can use variable with IceGrid descriptors, e.g. here it may want to use a 'server template' with a TestIP parameter.

- you can use DNS names instead of IP addresses in stringified proxies and endpoints. Probably not a great option here as you may not want "TestIP" to resolve to different IPs on different hosts.

Best regards,
Bernard

Hello

Thanks for the help, I'm gonna try to change the xml file so I can add all the properties in it. That should make my program a bit more simple.

Kind regards
