Solr 8.1.1, JMX and VisualVM

Hello,

While upgrading from 7.7 to 8.1.1, i noticed start.jar and SolrCLI no longer pop up in the local applications view of VisualVM! I CTRL-F'ed my way through the changelog for Solr 8.0.0 to 8.1.1 but could not find anything related. I am clueless!

Using OpenJDK 11.0.3 2019-04-16 and Solr 8, how can i attach my VisualVM to it?

Many thanks,
Markus

Hi,

This has to do with the new JVM flags that optimise performance, they were added roughly at the same time when Solr switched to G1GC.

In ‘bin/solr’ please comment out this flag: '-XX:+PerfDisableSharedMem'.

Hello,

Slight correction, SolrCLI does become visible in the local applications view. I just missed it before.

Thanks,
Markus
