oracle - Getting Repository dependencies -

-

i'm using informatica oracle rdbms. lately i've been struggling bit.

i got assignment query dependencies between each model/workflow , desired result this:

grand_model | grand_workflow | wait_4_model | wait_4_workflow  dwh_model1     wf_workflow1    dwh_model3      wf_workflow3_1  dwh_model1     wf_workflow1    dwh_model4      wf_workflow4_1  dwh_model2     wf_workflow2_1  dwh_model1      wf_workflow1

which means, wf_workflow1 in model dwh_model1 waits workflow wf_workflow3_1 in model dwh_model3 etc....

we have 3 types of workflows , delta (will contains word delta) dwh (same here) , calc(same here). workflow waits uses event contain both of models names, , workflow flags contain cmd contain grand_model name.

so far we've come this:

select distinct oa.subj_name grand_model,                 ol.subj_name wait_4_model_name,                 rep.workflow_name wait_4_workflow_name,                 a.flag_name,                 case                   when instr(upper(a.flag_name), 'dwh') > 0                    'dwh'                   when instr(upper(rep.workflow_name), 'delta') > 0                    'delta'                   else                    'calc'                 end connection_name   opb_subject@to_informatica_admin ol,        opb_subject@to_informatica_admin oa,        opb_task@to_informatica_admin t,        opb_task@to_informatica_admin tl,        opb_task_inst@to_informatica_admin ti,        rep_session_instances@to_informatica_admin rep,        (select t.task_id,                substr(t.attr_value,                       length(t.attr_value) + 2 -                       instr(reverse(t.attr_value), '/')) flag_name           opb_task_attr@to_informatica_admin t          t.task_type = 60            , instr(reverse(t.attr_value), '/') > 0) a,        (select t.task_id,                t.subject_id,                substr(t.pm_value,                       length(t.pm_value) + 2 -                       instr(reverse(t.pm_value), '/')) flag_name           opb_task_val_list@to_informatica_admin t          instr(reverse(t.pm_value), '/') > 0) l  ol.subj_id = l.subject_id    , a.task_id = t.task_id    , t.subject_id = oa.subj_id    , a.flag_name = l.flag_name    , ol.subj_name <> oa.subj_name    , l.task_id = tl.task_id    , tl.task_id = ti.task_id    , ti.workflow_id = rep.workflow_id

this query works! problem is, i'm getting worklets workflows well, of times last joins fails. don't know how avoid it..

Sass watch command compiles .scss files before full sftp upload -

-
i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...

filehandler - java open files not cleaned, even when the process is killed -

-
there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...

gridview - Yii2 DataPorivider $totalSum for a column -

-
i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...
