loadrunner - Simulating huge Json data in web_custom_request -


i need check performance of excel file upload in .net application mongodb. facing issue how fix this. here when excel file uploaded recorded in json format in web_custom_request. file content converted json format @ ui level , parsed server. have tried adding multipart/form data , file path no success. captured requests using fiddler same requests recorded.

below script recorded 2 records of data in body.

web_custom_request("import",     "url=http://www.neoint.ai/neointapidbqa/api/definitiondata/import/?isdefinition=true",     "method=post",     "targetframe=",     "resource=0",     "reccontenttype=application/json",     "referer=http://www.neoint.ai/neointwebdbqa/upload/enterprise%20sales%20area",     "snapshot=t16.inf",     "mode=html",     "enctype=application/json;charset=utf-8",     "body=[[{\"neointid\":\"\",\"definitionneointid\":\"\",\"esa_level_2\":\"ap\",\"esa_level_1\":\"hyderabad\",\"esa_level_3\":\"hyderabad\",\"esa_level_4\":\"secunderbad\"},"     "{\"esa_level_2\":\"ap\",\"esa_level_1\":\"vizag\",\"esa_level_3\":\"vizag\",\"esa_level_4\":\"vizag\"}],"     "[{\"\":\"\",\"templateid\":\"f854f762-a77e-4bb3-8945-07aefce52e36\",\"fileid\":\"62670\"}],\"mliquidateenterprise sales areaprofiles.xlsx\"]",     extrares,     "url=/neointapidbqa/api/getfailedprofiles/2", "referer=http://www.neoint.ai/neointwebdbqa/upload/enterprise%20sales%20area", enditem,     last);

logic implemented in application:

var file = $scope.selectedfile;             if (file) {                  var reader = new filereader();                  reader.onload = function (e) {                     var data = e.target.result;                     var dataobjects = [];                     var workbook = xlsx.read(data, { type: 'binary' });                     (var = 0; < workbook.sheetnames.length; i++) {                         var first_sheet_name = workbook.sheetnames[i];                          dataobjects.push(xlsx.utils.sheet_to_json(workbook.sheets[first_sheet_name]));                     }                     debugger;                     dataobjects.push($scope.selectedfile.name);                     if (dataobjects.length > 0) {                          var currentdate = $filter('date')(new date(), "mm/dd/yyyy / hh:mm:ss");                         var uplaodedfile = {                             "filename": $scope.selectedfile.name,                             "datetime": currentdate,                             "failedcount" : 0,                             "uploadstatus": "inprogress"                         };

i have check huge no of records in excel file , check performance.

can 1 advice me how solve this.

here basic structure, not accounting escaped quotes (backslash+double quote). have added line feeds ease reading 

 [     [         {         “neointid":"",         "definitionneointid":"",         "esa_level_2":"ap",         "esa_level_1":"hyderabad",         "esa_level_3":"hyderabad",         "esa_level_4":"secunderbad"         }         ,""         {         "esa_level_2":"ap",         "esa_level_1":"vizag",         "esa_level_3":"vizag",         "esa_level_4":"vizag"         }     ]     ,""     [         {         "":"",         "templateid":"f854f762-a77e-4bb3-8945-07aefce52e36",         "fileid":"62670"         }     ]     ,"mliquidateenterprise sales areaprofiles.xlsx" ]

record several different examples, 1 single row, 2 rows, ten rows. should find repeating pattern associated rows can build using foundation skills in c string construction. fileid looks unique identifier. suspect correlated value, need handle correctly well.

be wary of having heavy file i/o on load generators. find once above 10-15 virtual users going start waiting on read head virtual users contend access drive. same thing happens when have log level high , users have wait on write access. net result file system becomes drag anchor behind speed boat, slowing down load generator.

have considered placing values need in parameter file , using loadrunner functions associated advancing loadrunner parameter row pull in additional data in loop? large advantage here the loadrunner parameter files loaded ram @ beginning of test there no disk contention amongst virtual users on read. explains why cannot write parameter file virtual user , have new value read automatically virtual user b during same test....because file being written not being used - copy in ram being used test.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
