In this section, we provide IOC deployment details such as the App hosting the PLL IOCsTrigger Alignment IOC, as well as the IOC names name and the assigned CPUs CPU in both Dev and Production.
...
First, define the usual environment variables in the startup script.
Code Block | ||
---|---|---|

# ===========================================
# 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" )
epicsEnvSet("UNIT", "MS12" )
# 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") |
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.
Code Block | ||
---|---|---|

## 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/")

Tell the IOC where to find the list of record names and where they will be autosaved. Also, restore previously autosaved values.
Code Block | ||
---|---|---|
| ||
# =====================================================================
# Load database for autosave status
# =====================================================================
dbLoadRecords("db/save_restoreStatus.db", "P=${IOC_NAME}:")
# ============================================================
# If all PVs don't connect continue anyway
# ============================================================
save_restoreSet_IncompleteSetsOk(1)
# ============================================================
# created save/restore backup files with date string
# useful for recovery.
# ============================================================
save_restoreSet_DatedBackupFiles(1)
# ============================================================
# Where to find the list of PVs to save
# ============================================================
set_requestfile_path("${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") |
Load the YAML hierarchy and register configuration.
Load the relevant trigger alignment records.
Initialize and configure the trigger alignment Asyn driver to interface with the FPGA registers.
...
A complete list of the records to archive is provided below.
Initialize the IOC and logging capability.
