Hi Guys,

I use PB 2017 and connect to JDBC Derby which is java embedded DB, I experienced some slow queries, trying to adjust JVM heap size. based on document, there is way to config JVM, by setting

[HKEY_LOCAL_MACHINE\SOFTWARE\Sybase\PowerBuilder\2017\Java\PBRTConfig\PBJVMconfig]
"Count"="3"
"0"="-Xms512M"
"1"="-Xmx1024M"
"2"="-verbose:jni,class"

but seems it doesn't work, my questions are

1. does this approach still work or not?

2. if works, what's wrong with my setting

Very appreciated your feedback.

thank you

Frank
