VisualVM - not supported JVM

985823Oct 22 2015 — edited Oct 22 2015

Hi there

I am trying to use VisualVM 1.3.8 to monitor a Java application which is running on JRockit

and the CPU show "not supported for this JVM" and sample are all disabled.

I have read through other discussion page, and I am not quite sure if this because VisualVM is on the JDK1.8 and

my application is on Jrockit VM. If that is the case, I think I have give up VisualVM since most of our oracle products are

based on Jrockit, like hyperion.

Anyone could confirm this?

Thanks

Both queries work fine for me too with Oracle Database 12c Standard Edition Release 12.1.0.2.0.

Hello mNem,

thanks for your test and telling me where you did it. After trying different things I found out that my problem has to do with the usage of SQL-Detective as SQL-tool.

Hello all,

the reason for the error is the usage of SQL-Detective which seems to send some strange data to the Oracle-DB. After using SQL-Developer everythings works fine. Thanks for the tester to give me the idea to change my SQL-Tool.

Regards Carsten
