c# - Unable to begin a distributed transaction using Entiy Framework -


i'm having following error executing piece of code:

private bool _updatelist(sysinfo _sysinfo, list<plist> _plist) {     try     {          foreach (var p in _plist)         {             _context.spupdateplistapprovalflow(p.countryid, _sysinfo.user.jobroleid, p.src, p.id, p.status, _sysinfo.user.username);         }          return true;     }     catch (exception ex) //debug     {         throw; //throws error main try catch     } }

error

the operation not performed because ole db provider "msdasql" linked server "as400_linkedsrv" unable begin distributed transaction.

however, works fine when run stored procedure in sql management studio:

exec [dbo].[spupdateplistapprovalflow]         @countryid  = 123456,         @usertypeid = 23456,         @src = 1,         @id = '123456789',         @status = 30,         @username  = 'username'

i'm tired of digging answer nothing works... few things i've tried:

  • set transaction isolation level read uncommitted
  • insert multiple transactions in stored procedure

this sp has 2 sub stored procedures on it. 1 writes table of application's database, , updates table in as400.

ok, after half day trying solve i've solved it.

resolution

downgraded entity framework 6 entity framework 5 , distribuited transactions error has gone.

just pay attention, if you're going this, have change usings in code. ( in auto generated code in data model well)

ef 6 uses

using system.data.entity.core.objects

ef 5 uses

using system.data.objects;

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
