NewSize and SurvivorRatio needed with UseAdaptiveSizePolicy ?

[Sharma, Vipin K]

Hi All

I am working on an old java application and few days back we observed application crashed due to memory issue.

Below are the parameters we are using
-Xms32m -Xmx2048m -Xss1m -XX:+UseParallelGC -XX:NewRatio=2 -XX:NewSize=8m -XX:MaxNewSize=64m -XX:SurvivorRatio=25 -XX:+UseAdaptiveSizePolicy

Looking at these parameters few questions comes in mind and Looking for expert advice

1.       When we are using UseAdaptiveSizePolicy option , what is use of NewSize , MaxNewSize , NewRatio , SurvivorRatio. Shall I remove these ?

2.       Using above options are we overriding values set by UseAdaptiveSizePolicy ?


Thanks,
Vipin Sharma
