whenever

问题 I don't know what can be a reason and I spent already hours on the Web trying to figure out what's wrong in my case. I've checked official documentation and some thought from Tom Kyte on this and surely topic on stackoverflow about it. I use following code: .. < <(sqlplus -s /nolog <<EOF set errorlogging on WHENEVER OSERROR EXIT FAILURE WHENEVER SQLERROR EXIT FAILURE connect ${use}/${pwd}@${database} @$SCRIPTS_PATH/script.sql EOF ) echo Exited with $? I've emulated different failure scenarios

问题 I'm having problems deploying the Whenever gem to my production environment using Capistrano. The problem is stemming from a bundle exec whenever command that's triggering some 'missing gem' issues (yet running bundle install from the shell shows that everything is in fact there!). My feeling is that one of two things is happening: that Bundler isn't fully loading before bundle exec is being called, or that somehow there's a path issue that's running it in the wrong place. Here's what's going

问题 delayed_job is at http://github.com/collectiveidea/delayed_job Can delayed_job have the ability to do cron task? Such as running a script every night at 1am. Or run a script every 1 hour. If not, what are the suitable gems that can do that? And can it be monitored remotely using a browser, and have logging of success and error? 回答1: I worked on a project that tried to use DelayedJob to schedule future items. It sucked. Instead I recommend you use the whenever gem: http://github.com/javan

问题 We have a large deployment of around a dozen servers. We'd like to use the Whenever gem but I can't figure out a way to say which machine the cron jobs should go on! We only want these jobs to run on our server that does background jobs. Is there a way to specify this? 回答1: If you deploy the project with Capistrano and you use the default Whenever recipe, you can create a new Capistrano role role :whenever, "192.168.1.1" and set the role in your deploy.rb file set :whenever_roles, "whenever"

问题 This is my first processing jobs asynchronously I am implementing Sidekiq for background processing in my app. I will use it for reminder emails and in-app notifications. I am confused as to whether I should use Active Job to create a job that sends an email or a Sidekiq Worker to send an email. They seem to do the same thing and Rails 4.2 Active Job seems very new…is it replacing the need for a Sidekiq Worker? Below is the same sending a mailer code using an Active Job job and a Sidekiq

问题 Sorry quick question here from a relative Rails newbie. I'm trying to use the Whenever gem to schedule a number of rake tasks. I can't for the life of me get it to actually begin running the cron jobs on my development machine. Judging from other stackoverflow threads, it appears I should add this: set :environment, "development" to my schedule.rb file. But then what? And then how do I stop the cron jobs once they've started? Using Rails 3.2.3 in OSX UPDATE: the answer is to run $ whenever -w
