Synchronizing stored procedures in mysql -

-

i have 2 applications, both of them using same stored procedure in mysql. procedure synchronized, while 1 applications calls it, other 1 has wait.

is there way without altering codes of applications (that modifying stored procedure)?

thanks, krisy

you can absolutely within stored procedure without changing application code, bear in mind you're introducing locking issues , possibility of timeouts.

use get_lock() , release_lock() take care of synchronization. run get_lock perform synchronization @ start of stored procedure, , release_lock once you're done:

if (get_lock('lock_name_for_this_sp', 60))    .... body of sp    release_lock('lock_name_for_this_sp'); else    .... lock timed out end if

you'll need take care application timeouts longer lock timeout don't incur other problems.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
