Subject [jira] Commented: (DERBY-1568) run derbyall with low memory configuration for 10.2
Date Thu, 21 Sep 2006 08:27:22 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1568?page=comments#action_12436469 ] 
            
John H. Embretsen commented on DERBY-1568:
------------------------------------------

Regarding comparing 10.2 to 10.1:

There is a difference in how different versions of the test harness interprets and possibly
overrides heap size settings. To set non-default heap sizes when running a test suite (or
a single test) use the jvmflags system property when starting RunSuite (or RunTest). For example,
for running with 16 MB initial heap size and 32 MB maximum heap size, use:

* For 10.1.3.1 (and possibly other 10.1.x versions): 
        -Djvmflags="-ms16m -mx32m"
* For 10.2.1.x and later: 
        -Djvmflags=-Xms16m^-Xmx32m

For more details see DERBY-1614.

> Run derbyall with  a low memory heap and compare the results to 10.1.  This could help
flush out any  memory leaks or increased memory usage in 10.2. I am not sure exactly what
the minimum level is to run derbyall on 10.1. It may take some experimentation.
