  1. Redundant IOC improvements by LANL Goal: Rather than 2 IOCs talking on the same bus, as at DESY. We want to command redundant hardware as part of our new master timer system. Improvements that may be useful for everyone: • Added support for syncing field with SPC_DBADDR (waveform records) • Modified the Continuous Control Executive (CCEXEC) to support larger fields. • Made it possible to specify which records should be synced • Configurable via info nodes. • Modified e2db so that CapFast can be used to configure info nodes.

  2. Redundant hardware specific improvements • Added an option to only pause the channel access server instead of the entire IOC. • Call post_event on the slave when the database becomes synced with the master (CCEXEC_SLV_INSYNC state) so that passive records can be made to process on the slave. • Uses event-driven fanout records. • Can control the processing order. • Particularly useful for commands.
