Examples with ServerSynchronization com.arjuna.ats.internal.jts.orbspecific.interposition.resources.ServerSynchronization used on opensource projects

Example 1 with ServerSynchronization

use of com.arjuna.ats.internal.jts.orbspecific.interposition.resources.ServerSynchronization in project narayana by jbosstm.

the class ServerTransaction method register_synchronization.

/**
 * Registering a synchronization with interposition is a bit complicated!
 * Synchronizations must be called prior to prepare; if no
 * interposed-synchronization is used then either synchronizations would be
 * registered locally (and then ignored by the commit protocol) or they
 * would need to be registered remotely, which would mean a cross-address
 * space call for each synchronization!
 *
 * The first time a synchronization is registered locally, we register a
 * proxy back with the real coordinator. When that transaction commits, it
 * will call this proxy, which will then drive the locally registered
 * synchronizations (actually it calls appropriate on the transaction to do
 * this.)
 *
 * However, one-phase commit complicates matters even more since we call
 * commit on the interposed coordinator, which runs through the commit and
 * then the after_completion code before returning to the real coordinator's
 * commit call. Rather than separate commit and synchronization code
 * completely from the transaction (in which case we could just call the
 * commit portion here) we let after_completion get called before returning
 * the commit response, and simply ignore the real coordinator's subsequent
 * call to after_completion.
