Happy birthday to …. well … us :-)

Last year on September 1, the AskTom site was resurrected under Apex 5 with myself and Chris Saxon manning the fort to deliver as much value to the Oracle community as the esteemed previous custodian of the site did in the many years preceding us.

In the last year, we have

  • answered ~2,500 questions
  • taken and followed up on ~3000 reviews

It’s great fun and very rewarding working on the AskTom site.  We get to participate in the ever growing Oracle community, and it is like “free training” for Chris and I – we get to learn new things every day.

So I hope you’re getting as much value out of the site as we are.  We have plans to continue the site’s evolution to yield even more value in future.

Thanks!

After OpenWorld…

Don’t forget that there’s lot of great content still to come your way throughout the rest of the year.

I’ll be part of the OTN Tour in Bangalore, Sydney and Brisbane.

And for a change of pace… I’ll be doing a keynote  at UKOUG !  (I’m the person in the list below who isn’t a senior director or vice president Smile)

Hope to see you at some or all of these events.

 

Started at Amazon! … want to join me?

How important is "up to date" to you ?

I wrote a post a while back showing how one of the options with an Oracle Text index is to keep that index perfectly updated with its underlying table.  (Long termers with Oracle may know that this is a relatively recent addition to Text indexes, which historically were updated with calls to CTXSYS.CTX_DDL.SYNC_INDEX, either on demand or via the scheduler).

I also said that there is “no such thing as a free lunch”, as refreshing that index for every single commit introduces overheads.  So let’s explore that a little more thoroughly

Oaktable World 2016 Sept 19 & 20 is on !!

Having take a new job at Amazon just two weeks ago and moving to Seattle (!)  I didn’t have the time nor was it practical to set up Oaktable World  this year. Luckily Kellyn Pot’vin has taken over the mantel !

Denial of Service (DoS) attacks continue

It’s frustrating to have to spend time jumping off into web security and wordpress configurations when there are so many other things that are important to be doing. Today the DoS continued and the Jetpack solution didn’t seem to work. The other two solutions from Digital Ocean didn’t seem reasonable. One was to re-install wordpress with there install version. Nice that they offer a better security protected version but I didn’t feel like re-installing my wordpress. TH other option basically eliminated all access to xmlrpc.php. Looking around I found a plugin that does firewall work and had just added functionality for the xmlrpc.php problem, called ninjafirewall.

Problem is after I installed it I was getting 500 ” Internal server error” errors trying to access this blog.

Turns out the solution is to add a few lines to /etc/apache2/apache2.conf

such as

Denial of Service (DoS) attack on this site

This site had been running for a years with no big issues.
I had performance and system saturation issues about 3 years ago and then move the site to DigitalOcean.com.

DigitalOcean.com is inexpensive and the performance is awesome.

Then last Monday and every day since the site had been going down.
Simplest “solution” for me was just to get on and bounce the machine.

That cleared it up.

After this went on for a few days I contacted DigitalOcean saying I didn’t see how it could be an issue with them, but I’d asked anyway.

Sure enough they had identified the issue, which had nothing to do with them, and gave me the solution.

Read their solution page for more information.

OOW16 – The Park Central

Some of my sessions this year at OpenWorld are at the Park Central.

So…you’ve arrived at the Moscone Center, and you’re wondering “How do I get to the Park Central ?  After all…that’s where all of the hot talks will be” Smile

Here’s my simple guide:
