BigMemory Max 4.2.1 is the latest release. It includes Ehcache 2.9.1 and Quartz 2.2.1.

New Features

BigMemory Max 4.2 introduces following new capabilities:

  1. BigMemory Hybrid – Extensive, real-time auto-tuning for maximizing BigMemory Hybrid performance.
  2. Zero Down-Time Upgrades – Maintenance version upgrades can now be accomplished with zero down-time.
  3. WAN Replication – Support for even higher data limits and greater fault tolerance. REST APIs provided to monitor deployment.
  4. Management & Monitoring – Improved efficiency of management and monitoring to support larger numbers of clients connected to cluster.

Configuration Changes

  • New port dedicated to TMC - A new section, /tc:tc-config/servers/server/management-port, has been added to the Terracotta configuration file. This section specifies the port used by the Terracotta Management Console (TMC). The default is 9540. (Prior to 4.2, the TMC used the tsa-port and tsa-group-port.)
  • JMX port disabled - In the Terracotta configuration file, the section /tc:tc-config/servers/server/jmx-port is now disabled by default. To enable it, change the value of “jmx-enabled” from false to true in the Terracotta configuration file.

        al2.objectmanager.oidset.type=BITSET_BASED_SET
