sql server - How to execute a Java task on a scheduled basis, and on demand? -

-

my task dump large mssql table csv file uploaded elsewhere. task needs run nightly (or on scheduled basis), , should executable on demand (from web page). csv conversion must done in java.

this i've never implemented, seems common need. google research, came 2 options. have no idea if these have obvious pitfalls, or if there obvious (and superior) implementation options unaware of. use informed feedback/advice on how approach this.

  1. execute java application in web services container, apache tomcat. application run , it's business logic on whatever schedule, , tomcat make accessible web page. seems overkill, setup , maintain tomcat installation.

  2. package java program jar, , setup jenkins job (i have access jenkins server installation) execute main class on whatever schedule. , create jenkins jobs (in php or something) needed on demand executions. seems clean , easy option, there obvious pitfalls i'm missing?

there many tools job, no idea how pick right one.

also, general advice on how convert table csv in memory safe , time efficient manner appreciated.

the common way handling running job on schedule cron.

as accessing via webpage perhaps operated webservice, using somekind of rest or soap api. webservice run java logic , deliver csv either response or generate on file system on server.

as dumping data - should possible export csv mysql directly: dump mysql database plaintext (csv) backup command line

if there no requirement in java suggest simple webpage submit button calling mysqldump command. php script wrapper system call run mysqldump csv , dump location on http server.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
