Carl Harris updated AMQ-4694:
-----------------------------
Description:
This issue provides a patch to add support for using native flock (2) based
lock files. As discussed in AMQ-4378, using the Shared File System
Master/Slave configuration on an OCFS2 filesystem is complicated by Java's use
of POSIX locks. See the attached README for motivation and description of the
approach.
With this patch, a user can configure KahaDB to use a shared native lock file
(using flock) as follows:
<persistenceAdapter>
<kahaDB ...>
<locker>
<shared-native-file-locker/>
</locker>
</kahaDB>
</persistenceAdapter>
