Folks,
The SQLite version of CCDB is being regenerated nightly now. Find a
description of how to get it and use it on the wiki at
https://halldweb1.jlab.org/wiki/index.php/SQLite-form_of_the_CCDB_database .
This page is reproduced below.

SQLite-form of the CCDB database
The CCDB can be accessed as an SQLite file. Full history and read/write
access is supported. However note that there is no current automatic
mechanism for backporting changes from a modified SQLite database to
the main MySQL database.
By its nature SQLite requires no network connection and no additional
software is required.
Legal forms of the CCDB_CONNECTION URL are:
sqlite:///relative/path/to/file.db
sqlite:////absolute/path/to/file.db
Note that three "/"s indicate a relative path, four "/"s an absolute
path.
For example, sqlite database is /home/user/ccdb.sqlite then to use it
with the CCDB software,
setenv CCDB_CONNECTION sqlite:////home/user/ccdb.sqlite
or supply the URL directly to CCDB (interactive version shown),
ccdb -i -c sqlite:////home/user/ccdb.sqlite
To use it with JANA,
setenv JANA_CALIB_URL sqlite:////home/user/ccdb.sqlite
An SQLite database is created at midnight. The latest version is
available for download [5]here . Older versions of the CCDB can be
found at JLab in /group/halld/Software/calib/ccdb_sqlite .
