EM12c Utilizing After Hours Notification Schedule- Part II

Now that we learned in Part I how to create a notification schedule for a specified user so that it will only page one individual on an oncall rotation, I’ll now show you how to use this in conjunction with rulesets to complete the process of modernizing and automating

OEM After Hours Notification Schedule Option- Part I

I came across a discussion on Oracle-l on how after hours paging was handled for many companies and was kind of surprised how many DBAs still carry around a secondary pager/cell phone or are just expected to be woke up if on call or not.  I’m not one to go back to sleep once I’m woke, so I’ve been a proponent of EM notification schedules for after hours paging.

WordPress 3.8.3 – Auto Update

WordPress 3.8.3 came out yesterday. It’s a small maintenance release, with the downloads and changelog in the usual places. For many people, this update will happen automatically and they’ll just receive and email to say it has been applied.

I’m still not sure what to make of the auto-update feature of WordPress. Part of me likes it and part of me is a bit irritated by it. For the lazy folks out there, I think it is a really good idea, but for those who are on their blog admin screens regularly it might seem like a source of confusion. I currently self-host 5 WordPress blogs and the auto-update feature seems a little erratic. One blog always auto-updates as soon as the new a new release comes out. A couple sometimes do.

EM12c Auditing
