alive module Documentation

Record

aliveRecord.html: The alive record is used for determining where the heartbeat information is sent, as well as the extra environment variables that may be requested remotely.
aliveServer.html: This describes how one can implement a server for receiving and processing the heartbeat meassages, as well as making inquiries to the alive record about the extra information.

alive.db: This database is basically a straight implementation of the alive record itself. It creates a record of the name "$(P)alive". The RHOST is defined using "$(RHOST)". The rest of the fields that can be specified have defaults in them that can be overridden. The default for "$(RPORT)" is "5678", and for "$(HPRD)" is "15". If multiple IOC are to run on the same computer, then "$(IPORT)" for each IOC should have a different value, or all "$(IPORT)" values should be set to zero to allow the system to determine it. Only the first seven of the sixteen environment variable fields, "$(ENV1)" to "$(ENV16)", have defaults, being "ARCH", "TOP", "EPICS_BASE", "SUPPORT", "ENGINEER", "LOCATION", and "GROUP".

aliveRecord.adl: This is the medm ADL file for an alive record. All the fields are exposed on this screen.

Edit configure/RELEASE to specify the paths to EPICS base. There are no dependencies on any other modules.
Run Gnu Make to build.
Note that the alive module is not useful on its own, as it needs a remote server to send heartbeat information.

Configure an alive record to talk to a remote server daemon that understands how to talk to this type of record.
Make sure that IPSTS gets set to "Operable", otherwise the information port is not working.
Make sure that the HRTBT field is set to "On" (the default).
Make sure that the ISUP field is set to "Off" (the default).
Set ITRIG field to "Trigger". If ITRIG goes back to being "Idle", then the remote daemon has read the boot information, meaning the record is successfully talking to the daemon.
