[Clas12_software] ccdb server change for onsite usage

[Nathan Baltzell]

Hello All,

Our new clasdb-farm servers are ready and tested and provisioned to handle all load from the JLab farm.  It’s time for everyone to move onsite CCDB/RCDB read-access to these new servers to reduce load on clasdb, and run group accounts started using them a few weeks ago.  They provide in-sync replicas of clasdb's CCDB/RCDB databases, but *read-only* and *on-site* only.

*** Tomorrow we'll switch the /group/clas12/packages env setups to use the new servers automatically, e.g. any of these will direct your standard CLAS12 jobs to access clasdb-farm come tomorrow:

module load clas12/pro
module load clas12/dev
module load ccdb

Note, there are no software changes involved here, just environment variables.  If you’re still not using the modules env setup, then you’ll just need to set these env variables to point to the appropriate server for onsite jobs:

CCDB_CONNECTION=mysql:clas12reader at clasdb-farm.jlab.org/clas12
RCDB_CONNECTION=mysql:rcdb at clasdb-farm.jlab.org/rcdb
