EPICS Archiver Appliance Configuration Environment

Configuration Environment for EPICS Archiver Appliance for the Advanced Light Source Upgrade (ALS-U) Project at Lawrence Berkeley National Laboratory. Please check the latest discussions for your own customizations.

Please

One should understand that

• This reposiotry is a simple tool to help users to setup, maintain, and upgrade EPICS archiver appliance easily.
• This repository does NOT support multiple archiver instances.
• Archiving data is a very unique asset, which one has to handle seriously.
• I do not understant them all, but I want, and I am learning it continously still today.

Pre-requirement packages

git make sudo which

Debian 10/11 (EOL: 2024-06-01/2026-08-15)

#
make db.secure
make db.addAdmin
make db.show
make db.create
make db.show
make sql.fill
make sql.show

make build
make install
make exist
#
make sd_start
make sd_status

Descriptions

Install required packages

scripts/required_pkgs.sh

Tomcat 9

• Debian 10/11 : tomcat9 will be installed through make install.pkgs

• Others : See docs/README.tomcat.md

MariaDB

• JDBC connector

It is inside the site specific building procedure, so don't need to do anything.

• Create the DB and itsuser : archappl

If the MariDB has already admin account, please use it with the modification in configure/CONFIG_COMMOM. With the admin account, create db and user for the archiver appliance.

make db.create

If one cannot get results properly by make db.show, please run make addAdmin. Thus, from scratch, one should do

make db.secure
make db.addAdmin
make db.show
make db.create
make db.show

• Create and fill the tables

make sql.fill
make sql.show

Please see docs/README.mariadb.md for the further information.

JAVA and Ant

For JAVA and Ant configuration, please look at the generic Java Environment [1].

For the testing purpose, one can use the local JAVA and Ant environments. The java 11/12 and Ant.

See docs/README.javapkgs.md

EPICS Environment Variables

The default EPICS Environment Variables are defined as

% make vars FILTER=EPICS_

EPICS_CA_ADDR_LIST = localhost
EPICS_CA_AUTO_ADDR_LIST = YES
EPICS_CA_MAX_ARRAY_BYTES = 16384

Please see configure/CONFIG_EPICSENV. After deployment, one changes archappl.conf file in INSTALL_LOCATION, and restart it through systemd service or its master script. Note all 4 services should be restarted.
