Linear Collider Conditions Data framework
LCCD is distributed under the GPLv3 License
In order to build LCCD you need LCIO, ILCUTIL, CMake and optionally CondDBMySQL
if you have access to /cvmfs/ilc.desy.de/ then you will find all this packages under:
/cvmfs/ilc.desy.de/sw/x86_64_gcc49_sl6/
if you do NOT have acces to /cvmfs/ilc.desy.de/ or you do not have an SL6 machine the easiest way is to use ilcinstall (http://ilcsoft.desy.de/portal/software_packages/ilcinstall/).
Once the dependencies are resolved, issue the following commands:
mkdir build
cd build
cmake -C $ILCSOFT/ILCSoft.cmake ..
make install
make tests # optional step to build LCCD tests
- select the mysql version you want to use, e.g.
export PATH=/opt/products/mysql/5.0.26/bin:$PATH
- create a data directory
mkdir /tmp/mysqlDB
- init the database
mysql_install_db --datadir=/tmp/mysqlDB
- start the database
mysqld_safe --datadir=/tmp/mysqlDB &
or:
mysqld_safe --datadir=/tmp/mysqlDB --socket=/tmp/mysql.sock --log-error=mysql.log --pid-file=mysql.pid &
- b. you can stop the database - no need to do it now ]
mysqladmin -u root -p shutdown
- set root password (and remember it)
mysqladmin -u root password <mypassword>
- create users for LCCD [NOTE: THIS IS FOR TESTING ONLY - BE CAREFUL WITH USER RIGHTS/PRIVILEGES !!!!!]
mysql -u root -p
grant all privileges on *.* to calvin@localhost identified by 'hobbes' with grant option ;
grant all privileges on *.* to calvin@"%" identified by 'hobbes' with grant option ;
quit
If you built against CondDBMysql and built the tests, you can run them as follows:
cd ../test
./createcalfile hcal.slcio hcal
./readcalfile hcal.slcio hcal
./calfiletodb hcal.slcio hcal myhcal 100 200
./calfiletodb hcal.slcio hcal myhcal 200 300
./calfiletodb hcal.slcio hcal myhcal 300 400
./calfiletodb hcal.slcio hcal myhcal 400 500
./tagdbfolder /lccd/myhcal mytag01 "just a test tag"
./calfiletodb hcal.slcio hcal myhcal 0 500
./calfilefromdb myhcal 120 fromdb.slcio mytag01
./calfilefromdb myhcal 20 fromdb.slcio
It might be instructive to read the code in parallel and inspect the MySQL database, e.g.
mysql -u calvin -p
