Sadly I read the release notes, esp the:
The following HA data services are not initially available with the 4.0 release but might become available at a later time:
• Oracle GlassFish Message Queue
After I read "Oracle Solaris Cluster Data Service for Oracle GlassFish Server Message Queue Guide" at http://docs.oracle.com/cd/E23623_01/html/E26827/. yeah bad form on my behalf.
anyway, any ideas on this will be available sometime in the future?
