<ol>
<li> Mark reported that a CentOS 6.5 node (ifarm1401) has
been added to the nightly build. Matt had reported a
problem with this OS at JLab; the JLab locations of
CERNLIB and ROOT needed to be added.
</li>
<li> David led us through an <a
href="https://mailman.jlab.org/pipermail/halld-offline/2015-January/001928.html"
class="external text" rel="nofollow">email</a> he sent
concerning updates to the DAQ and TTAB libraries.
</li>
<li> Dmitry has released <a
href="https://mailman.jlab.org/pipermail/halld-offline/2015-January/001929.html"
class="external text" rel="nofollow">CCDB 1.04</a>.
Mark built it on the CUE, although the only functional
changes are in the CCDB command line interface.
</li>
<li> Richard Jones checked in a <a
href="https://mailman.jlab.org/pipermail/halld-offline/2015-January/001950.html"
class="external text" rel="nofollow">fix to the older
C-style HDDM API</a> to accommodate large BCAL arrays
in mcsmear.
</li>

Dmitry presented <a
href="https://halldweb1.jlab.org/talks/2015/rcdb_2015-02-04.pptx"
class="external text" rel="nofollow">slides</a> describing
the RCDB. It was originally designed to store configuration
files for the data acquisition system, but also can store
other run-oriented data. It was in service during the Fall
run, but did not get a lot of use. He described the general
structure and capabilities. See his slides for details.
<br>
Paul has a list of items that he would like to store in the
database. David is willing to help with putting values into
the RCDB from the online systems.

Changing Magnetic Field Settings</span><br>
<br>
Sean outlined the new scheme for getting the magnetic field
into JANA. Before now the file with the field had to be
specified on the command line. Now the CCDB stores a pointer
to the JANA resource (which is the file) and will load the
correct one depending on the run.

Sean ran down the status. See his <a

class="internal" title="OfflineMtg 20150203.pdf">Media:OfflineMtg
20150203.pdf</a> for details. He is indexing both EVIO and
REST formatted data. There is also a <a

title="EventStore">wiki page</a> for those who want to
learn more.
