ASF GitHub Bot commented on ARTEMIS-1112: ----------------------------------------- GitHub user bgutjahr opened a pull request: https://github.com/apache/activemq-artemis/pull/1204 ARTEMIS-1112: don't block live activation if another live server is running Instead of going directly into backup mode within the shared-store live activation, we just change the HA-policy to slave and return to the caller - ActiveMQServerImpl.internalStart(). The caller will then handle the backup activation as usual in a separate thread, such that EmbeddedJMS.start() can return. modified: artemis-server/src/main/java/org/apache/activemq/artemis/core/server/impl/SharedStoreLiveActivation.java You can merge this pull request into a Git repository by running: $ git pull https://github.com/bgutjahr/activemq-artemis master-as-backup Alternatively you can review and apply these changes as the patch at: https://github.com/apache/activemq-artemis/pull/1204.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #1204 ---- commit b3e39e3c2038de9c94251525a21f216d82cd0958 Author: Bernd Gutjahr <bernd.gutj...@hpe.com> Date: 2017-04-13T13:01:36Z ARTEMIS-1112: don't block live activation if another live server is running Instead of going directly into backup mode within the shared-store live activation, we just change the HA-policy to slave and return to the caller - ActiveMQServerImpl.internalStart().

The start() method hangs until the currently running live server > stops and this server actually becomes the new live server. > This is inconsistent with starting a server as slave server, where the start > method returns and doesn't wait until the slave took over as live server. > It also blocks the application that called EmbeddedServer.start() to proceed > it's normal operation. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
