multithreading - Multi threading in SSIS 2008 using Script Component with referenced custom DLL for SSRS Report Generation -


we have requirement in our project need generate reports our clients. these reports done using ssrs.

we having sql 2008r2 report server , ssis packages created done using 2008.

the report selection , format done based on business logic.the reports generated , saved common folder on server.

all logic have implemented within class library , created dll , registered gac.

we created 4 oledb source , script componenet whcih run paralled each other script component processes orders , generate report

all these 4 script component having the same dll referenced gac. when run ssis package, reports few orderd not getting created. when checked error log found below errors different orders.

error 1:

error 2 :

we wanted achieve multi threading functionality having different components create reports, above error not able make out needs corrected in order achieve desired output.

below code block generating error.

private static byte[] renderreport(list<reportparameter> param, string reportformat, string reporturl)     {         string[] streamids;         warning[] warnings;         byte[] reportoutput = null;         string mimetype, encoding, extension, deviceinfo;              using (reportviewer rptstandardreport = new reportviewer())             {                 rptstandardreport.serverreport.reportserverurl = new uri(settings.default.reportserver);                 rptstandardreport.serverreport.reportservercredentials.networkcredentials = new networkcredential(settings.default.reportserverusername, settings.default.reportserverpassword);                 rptstandardreport.serverreport.reportpath = reporturl;                 rptstandardreport.serverreport.setparameters(param);                 deviceinfo = "<deviceinfo><simplepageheaders>true</simplepageheaders></deviceinfo>";                 reportoutput = rptstandardreport.serverreport.render(reportformat, deviceinfo, out mimetype, out encoding, out extension, out streamids, out warnings);             }        }

any suggestion or appreciated.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
