i have ssis package uses sql statements pull data 10 postgres databases identical schemas different data. package written job 10 tasks, each task has hardcoded values indicating server pull data from. source sql doesn't change, , db schemas across 10 source servers identical, data different. basically, we're running data extract against 10 instances of app's backend on loop. we use 32-bit odbc driver connect postgres sql server 2008 r2 via system dsn connections. don't use fetch because works larger reports fails smaller ones. on target sql server side, after each run result data each sql statement gets appended same table source id. way can query single table or of 10 sources' data. each day package runs, gets truncated , reloaded. on source side, data staged via backup/restore around 6 am; our jobs start around 8 am. ssis etl dumps data intake bucket, , actual final insert user-facing tables happens via stored procedure. to summarize, we have p...

i using code: my code to output table. question how possible updating in page without reloading? thank you either use ajax requests or if feel good, try html5 websockets : add trigger table update / insert / delete , , keep clients up-to-date. ajax means you'll doing request client server every few seconds, check if have changed , if so, you'll download new data (usually devs use json), , update table using javascript data. with websockets , event starts server side : whenever db table updated, send request server clients tell them update table new data. you'll find plenty of examples on web, searching either ajax or websockets . if don't know are, i'd recommend go ajax , setting-up websockets server php might tricky.

in current implementation of doorkeeper, when access_token refreshed doorkeeper sends new refresh_token.this valid implementation becomes problematic when there concurrent apis calls client side (ios, android) calling refresh access token @ same time. means there @ least 1 thread ending expired tokens cant refresh. anyone has solution race condition? we've solved before (not doorkeeper) couple of different ways. request queue : on our mobile apps we've implemented request queue, , before request made check if token needs refreshed pause queue, refresh token, unpause again. no changes server required in case this has tradeoffs (you need sync request threads etc), pretty reliable @ stopping refresh contention without needing modify server. refresh jitter , jwt : since using jwt (where access_token expiry written token , not revoked @ server end), can add random number of "jitter seconds" refresh expiry each time check. decreases likelihood of 2...
