[Mondrian] JUnit tests suite - recommended changes. #625

[Julian Hyde]

I've not seen that cognos test failing with out-of-memory. Maybe, as you
suspect, 64 bit uses 2x the memory. Try doubling to 512Mb.
 
What database are you running against? There have been 6 errors against
Oracle for some time. I emailed Matt Campbell about them earlier today.

Hi all.



I pulled the latest source code snapshot from the Hudson dashboard.



Unzipped in to a clean folder, edited the properties file to put in my
database connection details, and using java version:

mondrian-3.1-SNAPSHOT% java -version

java version "1.5.0_14"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)

Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_14-b03, mixed mode)



I ran "ant test".



My results were surprising for two reasons.



First, I got 6 failures, and 1 error.



Second, the error I got was an out-of-memory error....





     [java] There was 1 error:

I am still working on the 6 failures, but, the fix for the error is to
increase the size of the heap for the junit.jvmargs property in the
build.xml file. 256m is too small it seems. (I used 1g, but perhaps that's
too much?)



This would be an easy change.



Perhaps it is because I am using 64bit on linux?



Thanks



Rolf
