Yeah, I think he's working on his CCIE and wants no distractions.

TIL I hate programming with MYSQL.

On that note, there's developers, and then there's that sub-variant of developer known as DBAs.
We need a new animated GIF for them alone. And the even more irritating sub-sub-variant, the MS-SQL DBA who believes that a stretched layer 2 domain is the only possible way of building DR, because that's what his preccccious MS SQL cluster requires. I'm pretty sure they're even worse than *spits* Oracle developers.

Oracle DBAs: :oracle:

MSSQL DBAs: :mssql:

Network admin's reaction after a DBA cons helpdesk into an emergency change request: :whatudo:

Nope, Oracle is the worst. Somewhere in their documentation for 11g it states that you should turn off spanning-tree on the network because the latency introduced will cause the heartbeat to fail. This came up during a deployment meeting during an Oracle RAC deployment. They wanted layer two adjacency, and no spanning-tree.

Turn off spanning-tree?

TIL (well technically yesterday) that M$ documentation is to never be trusted. Our data storage system is Microsoft's StorSimple which is actually a really neat product IMO. M$ support told us that we needed to do an upgrade to our primary storage system. The support engineers and the upgrade documentation said this was a non-disruptive upgrade that could be ran during normal production hours. They were wrong! I started the upgrade yesterday morning at about 9:30AM. We regained access to the over 25TB's of data on that storage system (with the help of previously mentioned M$ support engineers) at 1:30PM. The upgrade still needs to be done but M$ is trying to figure out what went wrong first before we attempt that again lol.

:whatudo:

I am now of the opinion that there is no upgrade that can be done without disruption during normal business hours.

Zero downtime upgrade of an HA pair? Great. Then we will have zero downtime during the upgrade after normal business hours.

With this new job I have discovered that when you are global with more non-US locations than US locations there isn't really a "after business hours" window. The philosophy here is schedule a maintenance window and just make sure it is announced to everyone. Unfortunately you have days like yesterday where your 1 hour "scheduled" window turns into 4 hours lol.

I get what you are saying though. At my previous job being in a service provider environment upgrades even if "non-disruptive" they were always done after that clients business hours.

Here at Worldwide Global Multinational, we can schedule site work pretty well, since there will be staff at other locations in their normal work day that can do work remotely for a site after its business day. For upgrades that affect the global deployment, when the USA goes home on Friday night, it's time to start the upgrades. The Mideast might get a few bumps on Saturday and Sunday, but as long as everything is working before the guys in the corporate HQ in Europe go online on Monday, it's a good upgrade.

We don't have the luxury of IT staff in all locations. We do have staff in other time zones but they are more setup computers and plug stuff in kind of techs. Our only senior level staff are all located in the US.

We have senior staff on three continents, and are able to follow the sun. By that, I mean that Asia shifts to an 1100-2000 schedule so that they can cover most of the Europe hours. We may pick up a few more support locations, but not with senior IT staff in them.
