I just discovered that TNS names in Oracle stand for "Transparent Network Substrate".
I feel so happy that I need to share this "secret" with the rest of the universe.

Hybris setup issue: Unsupported major.minor version 52.0
Thu, Mar 23rd 2017 3:49p   Francesco De Collibus
While I was typing the final "ant all" command for hybris, it miserably failed with the following exception hybris/bin/platform/resources/ant/antmacros.xml:123: java.lang.UnsupportedClassVersionError: de/hybris/ant/taskdefs/DbDriverValidator : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) Even though a "java -version" gave me back version 8, ant is still using $JAVA_HOME variable. So you have to change it into the script. My suggestion is that y

If you can't install Oracle Express XE 11g 2 on Windows...

I spent the whole afternoon trying to set up a Oracle Express instance without any success. I had the drivers installed, but I could not uninstall them. It looked like the main instance was not correctly set up. After looking around, I noticed that even after complete uninstall of Oracle XE still the ORACLE_HOME environment variable was still there. I tried again manually removing it from System Variables and then reinstalling... and it finally worked!

How could I be so stupid using hibernate criteria with timestamp?
Wed, Aug 31st 2016 8:06p   Francesco De Collibus
I needed to make a query to find all records valid today for columns with effectiveFrom and effectiveTo range I spent a couple of hours trying to understand why criteria.add(Restrictions.ge("effectiveFrom",currentDate.getTime())); criteria.add(Restrictions.le("effectiveTo",currentDate.getTime())); was giving no results. After many trials and attempts with other criteria tricks, I remembered that hibernate is not comparting if currentDate.getTime is greater than ef

Java ALWAYS passes by value (and it is ALWAYS an interesting discussion)
Thu, Jun 23rd 2016 4:47p   Francesco De Collibus
Always good as a refresher. So, when calling a methodFor primitive arguments (int, long, etc.), the pass by value is the actual value of the primitive (for example, 3).For objects, the pass by value is the value of the reference to the object. http://stackoverflow.com/questions/40480/is-java-pass-by-reference-or-pass-by-value

How I ran Gradle with cntlm
Wed, May 25th 2016 7:20a   Francesco De Collibus
I was behind a corporate firewall and had to run gradlew (gradle) from Cygwin. The system was running a cntlm authentication proxy. I ran the following command export http_proxy=http://127.0.0.1:3128/ export https_proxy=$http_proxy Then I ran ./gradlew -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3128 -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 I hope it helps

UNION makes ALL the strength
Tue, Apr 5th 2016 1:47p   Francesco De Collibus
Following the advice from a very expert consultant, I changed my views from an UNION between two select from the same table to UNION ALL and the performance improvements were simply amazing. Before doing so, I had verified that the query were returning different results with the INTERSECT command before doing so. The difference is that UNION verifies that records are unique, while UNION ALL doesn't. The performance gain is very remarkable
