i trying write deadlock proof stored procedure. based on following concept. i have been trying write stored procedure based on following concept. procedure try drop constraint on table , if in case detects deadlock situation, wait time before trying again. important thing should retry in case of deadlock or nowait error, other errors handled via exceptions. procedure test begin <<label>> drop constraint on table if (deadlock(ora-00060)/nowait error (ora-0054)) detected sleep 60 seconds goto label exception when others. it great if of experts please me this. similar example highly helpful. thank help. while people harbour irrational aversion goto remains true can implement same logic without using construct. true here: simple while loop necessary: create or replace procedure drop_constraint_for_sure ( p_table_name in varchar2 , p_constraint_name in varchar2 ) x_deadlock exception; pragma exception_init(x_deadlock, -60); x

i developed simple bash script ( s3perf ) measures required time carry out different object-based storage service operations. tool creates bucket, uploads , downloads set of files , afterwards removes bucket. consumed time per operation measured , printed out on command line. my script uses tools s3cmd , mc , swift client interaction storage services. does simple way exist eliminate data transfertime measurements? idea 1: measure first network speed iperf , calculate required time upload/download files. these values substracted time values when interacting storage services. idea 2: upload , download files (e.g. scp or wget) first steps , measure required time. these values substracted time values when interacting storage services. both ideas not result in exact values because each operation individual , data transfertime (at least little bit) different. wiki

reshift newbie here - greetings! trying unload data s3 redshift, using java program running locally issues unload statement on jdbc connection. @ point jdbc connection appears lost on end (exception caught). however, looking @ s3 location, seems unload runs completion. true unloading rather small set of data. question is, in principle, how unload supposed behave in case of lost connection (say, firewall kills or kill -9 on process executes unload)? run completion? stop senses connection lost? have been unable find answer neither rtfm'ing, nor googling... thank you! the unload run until completes, cancelled, or encounters error. loss of issuing connection not interpreted cancel. the statement can cancelled on separate connection using cancel or pg_cancel_backend . http://docs.aws.amazon.com/redshift/latest/dg/r_cancel.html http://docs.aws.amazon.com/redshift/latest/dg/pg_cancel_backend.html wiki
