java - How can I auto select a webservice? -

-

my application needs connect web service xml data. have primary , secondary web service.

what best way failover secondary web service if primary fails respond? how set timeout waiting primary?

thanks

the best solution set vip web service, , have failover automatically. way application cares 1 endpoint , doesn't need worry details.

if want handle java code, depends on libraries using connect web service. if using core java, might this:

try {    url primaryurl = new url(web_service_endpoint);   httpurlconnection con = (httpurlconnection) primaryurl.openconnection();   con.setconnecttimeout(5000); //set timeout 5 seconds    //try retrieving xml  } catch (java.net.sockettimeoutexception e) {   //try connecting secondary web service   //maybe recursive method call different url or }

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
