GlueX Implementation of the RCDB

SQLite Database Files

The latest version of the RCDB, in SQLite form can be downloaded from

https://halldweb.jlab.org/dist/rcdb.sqlite

On the disk at JLab this is

/group/halld/www/halldweb/html/dist/rcdb.sqlite

This file is created daily, but only if changes to the RCDB have been made during the previous day. There is a cron job that runs on sandd1.jlab.org as user gluex at midnight to do this.

Backup Scheme

Each daily version of the SQLite database is written to

/cache/halld/home/gluex/rcdb_sqlite

a location on the write-through cache. They are thus archived to tape before old ones are automatically deleted.
