i have need execute 5000 select statements on datasource , pull results , insert 5000 values table of different data source. for 5000 select statements(all different sqls) exeuting 1 one (this taking more time) for 5000 inserts doing jdbctemplate.batchupdate() the above job needs executed every 30mins. have configured spring batch job triggered every 30 mins cron. once method called complete 5000 select statements it's taking more 300s complete websphere throwing timeout exception. says global transaction time exceeded 300s. i know can increase timeout in websphere can't since in production server profiles configured default. can suggest me better way handle this. you can increase transaction timeout on current thread using transaction.settransactiontimeout(int seconds) on usertransaction before calling transaction.begin() http://docs.oracle.com/javaee/6/api/javax/transaction/usertransaction.html

what data type should use store json encoded array in mysql version 5.6 json data type not available? far i'm thinking store text or varchar. how have store it? it depends on length of json data going store. if it's not long can use varchar, have limit of 64k: manual says: length can specified value 0 65,535. effective maximum length of varchar subject maximum row size (65,535 bytes, shared among columns) , character set used. so if expect have huge objects, use text. since mysql 5.7.8 you're able use native json data type, though.

in java possibility string.valueof(float) format float number differently based on operating system code run on, version of java and/or operating systems locale. for example, float number 4.5 ever formatted "4,5" instead of "4.5"? string.valueof(float) calls float.tostring() . float.tostring() calls intern sun.misc.floatingdecimal.tojavaformatstring(float) the result string never contain sign , bacause of hard-coded '.' (ascii: 46) inside binarytoasciibuffer.getchars(chars[]) you can see if decompile sun.misc.floatingdecimal class (in case java 8 jdk) or see (similar) implementation in openjdk.

if babel translates es6 es5 , outputs es5 file why browser need include polyfill file if app output file contains es5 code ? babel translates es6 (and newer) code es5 code. example, rewrites arrow functions ( () => {} ) es5 functions ( function() {} ). however, es6 more new syntax. https://babeljs.io : since babel transforms syntax (like arrow functions), can use babel-polyfill in order support new globals such promise or new native methods string.padstart (left-pad). uses core-js , regenerator. check out our babel-polyfill docs more info. all new functions need implemented polyfill. , these polyfills must included globally project. otherwise every usage of es6 function replaced implementation of function in es5 code. if use e.g. array#findindex ten times, transpiled code contain implementation ten times. why polyfills have added globally , not added transpilation step.
