First, assume your schema is called ‘D’. To see the cursor parameters: <pre lang="sql"> show parameter cursor; See this faq for the meaning of these parameters: http://www.orafaq.com/node/758 To check the amount of “open” and “closeable” run: <pre lang="sql"> select a.value, s.username, s.sid from v$sesstat a, v$statname b, v$session s where a.statistic# = b.statistic# and s.sid=a.sid and b.name = 'opened cursors current' AND username = 'D'; To find the session which is having the largest number of cursors:...

I guess nobody is still using flex, but I still have to debug legacy code and I run into this nice compiler error: [mxmlc] Error: null [mxmlc] [mxmlc] java.lang.NullPointerException [mxmlc] at flex2.compiler.util.QName.hashCode(QName.java:131) [mxmlc] at java.util.HashMap.hash(HashMap.java:366) [mxmlc] at java.util.HashMap.getEntry(HashMap.java:466) [mxmlc] at java.util.HashMap.get(HashMap.java:421) [mxmlc] at flex2.compiler.util.QNameMap.get(QNameMap.java:46) [mxmlc] at flex2.compiler.as3.reflect.Class.getVariable(Class.java:194) [mxmlc] at flex2.compiler.as3.binding.DataBindingFirstPassEvaluator.findEvents(DataBindingFirstPassEvaluator.java:702) [mxmlc] at flex2.compiler.as3.binding.DataBindingFirstPassEvaluator.findEvents(DataBindingFirstPassEvaluator.java:662) [mxmlc] at flex2.compiler.as3.binding.DataBindingFirstPassEvaluator.watchExpression(DataBindingFirstPassEvaluator.java:959) [mxmlc] at flex2.compiler.as3.binding.DataBindingFirstPassEvaluator.evaluate(DataBindingFirstPassEvaluator.java:635) [mxmlc] at flash.swf.tools.as3.EvaluatorAdapter.evaluate(EvaluatorAdapter.java:85) [mxmlc] at macromedia.asc.parser.QualifiedExpressionNode.evaluate(QualifiedExpressionNode.java:43) [mxmlc] at flex2.compiler.as3.binding.DataBindingFirstPassEvaluator.evaluate(DataBindingFirstPassEvaluator.java:436) [mxmlc] at macromedia....

The problem consist of creating a timelapse made of photos which have been taken with a camera which has been removed and attached to a tripod during a few months thus creating a lot of shaking. Solution, use hugin to align photos: <pre lang="bash"> #!/bin/bash align_image_stack -v -a$1 -s 2 *.jpg mkdir base for i in $(find . -maxdepth 1 -name "*.tif"); do n=".$(echo $i | cut -f2 -d".").jpg"; convert $i $n && mv $n base; done rm *....

After Oracle 11g very good experience with installing on Ubuntu I had high hopes for 12C also. They crumbled down quite fast. This is the summary of almost 2 days lost trying to install oracle on Ubuntu with the ups and downs. Conclusion First the conclusion: my personal conclusion is that oracle 12c does not work, with an acceptable amount of effort, on Ubuntu 14.04. It should be possible to install it following a guide but it’s by no means comparable to an 11g install....

After upgrading from 3.4 to 3.6 my JGroups code stopped working.

Migrating from ojdbc14.jar to ojdbc6.jar is not, as one might think, completely seamless.
