EAServer on Solaris - -Troubleshooting Tip for Crashes or Hangs
Sun Solaris versions prior to 2.9 provide several threading models for Java
server applications. These are described in detail at http://java.sun.com/docs/hotspot/threads/threads.html.
In Solaris 2.8 and earlier, the default model uses a many-to-many mapping
These issues due not occur when using the 1-1 threading model on Solaris 2.8 or 2.9. Therefore, for highly stressed servers, Sybase suggests trying the 1-1 threading model if you encounter hangs or crashes.
EAServer on Solaris 2.9Solaris 2.9 supports only the the 1-1 threading model, therefore these issues are inapplicable / do not occur on that version.
EAServer on Solaris 2.8On Solaris 2.8, you can run EAServer with 1-1 threading by adding /usr/lib/lwp to the front of the LD_LIBRARY_PATH setting.
This setting causes the server to run with an alternate version of the threading libraries that default to the 1-1 model.
EAServer on Earlier Solaris VersionsOn earlier Solaris versions, you can append the following to the server property com.sybase.jaguar.server.jvm.options
at http://java.sun.com/docs/hotspot/threads/threads.html, this setting significantly reduced performance.
