Amazon announces Performance Insights

December 2nd, 2016
Excited to see the announcement of Amazon RDS Performance Insight feature for database performance monitoring and tuning. Having met the team for this project I can say from my personal view point that the importance and future success of this feature is clear as day to me. The team is awesomely sharp, the architecture is super impressive, and this is by far the most exciting performance monitoring and feedback system I've been involved with,  surpassing the work I've been involved in on Oracle's performance monitoring and tuning system and Embarcadero's DB Optimizer and Quest Foglight and Spotlight. Not only does the feature ...

SQL*PLus on Mac

December 1st, 2016
I would think installing SQL*Plus on the Mac would be point, click download, point click, install bam it works. Nah It did install mostly straight forward on my old Mac. Got a new Mac and no dice. Tried installing myself guessing at the downloads. First of all why isn't there just one download? Downloaded instantclient and instantclient with SQL*Plus which turns out to be correct, but no dice. Still got errors. Got errors. Gave up. Came back again to look at it yesterday and followed this: https://tomeuwork.wordpress.com/2014/05/12/how-to-install-oracle-sqlplus-and-oracle-client-in-mac-os/ worked like a charm. Then I ran a shell script that used SQL*Plus oramon.sh and get the error dyld: Library not loaded: /ade/dosulliv_sqlplus_mac/oracle/sqlplus/lib/libsqlplus.dylib Referenced from: ...

Started at Amazon! … want to join me?

August 29th, 2016
(Disclamer: any opinions expressed here are fully my own and not representative of my employer) photo by alvaroprieto  (cc 2.0) Super excited to be working at Amazon on my passion which is performance data visualization and database monitoring. Suffice it to say this is the most excited I've been about work in my career and I've had ample opportunity to work on database performance in the past such as at Oracle (where I helped design the performance pages and designed Top Activity page), at Quest (now Dell) on Spotlight, on my own free tools ( ASHMon, S-ASH, W-ASH, Oramon etc)  and at Embarcadero ...

Denial of Service (DoS) attacks continue

August 24th, 2016
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 ...

Denial of Service (DoS) attack on this site

August 22nd, 2016
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 ...

Evolution of Masking Vendors

April 25th, 2016
Masking with Delphix (where duplicate blocks are shared making a new copy almost free storage wise and almost instantaneous) has 4 big advantages Instant data, no copying Ease of Use Consistent across data centers and databases vendors Master/Slave Virtual Data Masking Delphix masking and virtualization is the most advanced solution in the market place, because Delphix doesn't provision data. Instead of provisioning data, Delphix sets up pointers back to existing data for a new clone. When that new clone tries to modify data, the existing data stays unchanged, and the changed data is stored elsewhere and only visible to the clone that made the change. This allows Delphix to ...

Delphix replication and push button cloud migration

April 22nd, 2016
Someone just asked on the Delphix Forums whether they could test Delphix replication with the free version of Delphix called Delphix Express. I'd never tried, so I sat down to try and was amazed at how easy it was. One of the coolest things about Delphix replication is that it makes it super easy to migrate to the cloud and also to fall back to in house if need be.  For cloud migration, I just set up a Delphix engine in house and one in a cloud, for example Amazon EC2. Then I just give the in house engine the  credentials to replicate ...
