iis - multiple users accessing wcf, stalls service -

-

we have setup:

1) web site fronts functionality user, 1 of modules connect separate web service (wcf) reference.

2) internal web service visible within network provides separate functionality public website. render , return data , rdlc reports byte array.

when tried running web service's application pool under network system, website failed access it. when set web service local system works.

the issue left whenever more users try access web service website, somehow, web service stalls , pool refresh required make running again. i've checked settings of iis web service , connections set unlimited.

help!

as said in comment, serious work typically recommend against using iis application host. has several drawbacks (it dictates service address, has deal app pools , recycling etc.)

instead, production services in self-hosting manner, e.g. inside windows nt service. gives me lot more flexibility: i'm in full control of aspects, including addresses, , can start/stop services @ will, , i'm not @ mercy of app pools being recycled.

basically, need create instance of servicehost wcf runtime, , give service class host, , optionally 1 (or multiple) base addresses service exposing endpoints at.

servicehost svchost = new servicehost(typeof(mywcfservice));  // optionally set additional properties here, if needed  svchost.open();  // now, host open , accepting

when want stop listening requests, call svchost.close() , service host gone.

when package nt service, typically setup , .open() of service host in onstart method, , handle svchost.close() in onstop method of nt service.

this app contains servicehost doesn't have nt service - testing, it's easy put servicehost console app, start , bring wcf service life, test/debug/enhance, , close console app again. easier mucking around iis, virtual directories , stuff that, in opinion.

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.
