Generic variable definition
First, define the usual environment variables in the startup script.

# ENVIRONMENT VARIABLES
# ===========================================
# Setup environment variables
epicsEnvSet("LOCATION","SYS0" )
epicsEnvSet("SYS_PV", "TPR:SYS0:MS12" )
epicsEnvSet("IOC_PV", "SIOC:SYS0:MS12")
epicsEnvSet("IOC", "sioc-sys0-ms12")
epicsEnvSet("SUBSYS" ,"trigAlign" )
epicsEnvSet("SYS", "SYS0" )

# Support Large Arrays/Waveforms; Number in Bytes
# The default max size for a channel access array is 16Kb
epicsEnvSet("EPICS_CA_MAX_ARRAY_BYTES", "80000000") |
Common setup
Load dbd and IOC health/monitoring records. Also, set up autosave and load the LCLS access configuration file. Finally, copy the archive file in $IOC_DATA to enable record archiving.

## Load dbd
dbLoadDatabase("dbd/masterSource.dbd", 0, 0)
masterSource_registerRecordDeviceDriver(pdbbase)
## Environment variables
epicsEnvSet("ENGINEER", "MATT WEAVER")
epicsEnvSet("STREAM_PROTOCOL_PATH", "${TOP}/db")
## Tag log messages with IOC name
epicsEnvSet("EPICS_IOC_LOG_CLIENT_INET", "${IOC}")
## Load records
# **** Load iocAdmin databases to support IOC Health and monitoring ****
dbLoadRecords("db/iocAdminSoft.db", "IOC=${IOC_NAME}")
dbLoadRecords("db/iocAdminScanMon.db", "IOC=${IOC_NAME}")
dbLoadRecords("db/iocRelease.db", "IOC=${IOC_NAME}")
## Autosave initialization
< $(TOP)/iocBoot/common/autosave_init.cmd
## Channel Access Security:
# This is required if you use caPutLog.
# Set access security file
# Load common LCLS Access Configuration File
< ${ACF_INIT}
## Update archive pv list in ${IOC_DATA}
system("cp $(TOP)/archive/${IOC}.archive ${IOC_DATA}/${IOC}/archive/")

Autosave initialization
Tell the IOC where to find the list of record names and where they will be autosaved. Also, restore previously autosaved values.

# =====================================================================
# Load database for autosave status
# =====================================================================

# ============================================================
# If all PVs don't connect continue anyway

# ============================================================

# useful for recovery.

# Where to find the list of PVs to save
# ============================================================
set_requestfile_path("${IOC_DATA}/${IOC}/autosave-req")
# ============================================================
# Where to write the save files that will be used to restore
# ============================================================
set_savefile_path("${IOC_DATA}/${IOC}/autosave")
# ============================================================
# Prefix that is use to update save/restore status database
# records
# ============================================================
save_restoreSet_status_prefix("${IOC_NAME}:")
## Restore datasets
set_pass0_restoreFile("info_positions.sav")
set_pass1_restoreFile("info_positions.sav")
set_pass0_restoreFile("info_settings.sav")
set_pass1_restoreFile("info_settings.sav") |
Besides the auto-generated record names for autosave, copy the manually generated list of records to be autosaved and restore their previously autosaved values.
Code Block |
---|
|
# Copy over the manual settings request file
system("cp $(TOP)/autosave/${IOC}.req ${IOC_DATA}/${IOC}/autosave-req/")
# Load manual settings from autosave
set_pass0_restoreFile("${IOC}.sav")
set_pass1_restoreFile("${IOC}.sav") |
Real-time environment & databases
