---+!!The EMIR configuration for CREAM The [[https://twiki.cern.ch/twiki/bin/view/EMI/SERP][EMIR-SERP]] allows CREAM to publish all its relevant information already available in the local resource BDII to a specified [[https://twiki.cern.ch/twiki/bin/view/EMI/EMIRegistry][EMI Registry]] (EMIR) DSR. The configuration can be explained by simple steps: * check if the resource BDII is up and running by executing <verbatim> ldapsearch -x -h localhost -p 2170 -b 'GLUE2GroupID=resource,o=glue' objectCLass=GLUE2Service </verbatim> the command should list the CREAM service(s) installed on the machine. If this is not the case, please check the CREAM configuration * install the emir-serp <verbatim> sudo yum install emir-serp </verbatim> * edit the configuration file /etc/emi/emir-serp/emir-serp.ini, providing the URL for the EMIR DSR and the URL for the resource BDII <verbatim> ... url = http://emitbdsr1.cern.ch:9126 ... [servicesFromResourceBDII] resource_bdii_url = ldap://localhost:2170/GLUE2GroupID=resource,o=glue ... </verbatim> * you can change the update interval <verbatim> # Period of registration/update messages # Mandatory configuration parameter # Value is given in hours period = 1 </verbatim> * and the time EMIR will be told to consider the information valid <verbatim> # Time of registration entry validity # Mandatory configuration parameter # Value is given in hours validity = 2 </verbatim> * you might want to set the logging level to debug the first time you start the service <verbatim> verbosity = debug </verbatim> * start the service <verbatim> sudo service emir-serp start </verbatim> * check the log file for an entry like <verbatim> 2013-01-09 12:49:22,359 DEBUG EMIR service on url 'http://emitbdsr1.cern.ch:9126' is running since Mon Nov 26 14:09:35 CET 2012 2013-01-09 12:49:22,359 DEBUG Daemon starting... 2013-01-09 12:49:22,373 DEBUG Daemon started 2013-01-09 12:49:22,373 DEBUG Registering service entries 2013-01-09 12:49:22,374 DEBUG Retrieving data from ldap://localhost:2170/GLUE2GroupID=resource,o=glue 2013-01-09 12:49:22,394 DEBUG REGISTRATION: Endpoint ID: cream-27.pd.infn.it_org.glite.ce.CREAM; URL: https://cream-27.pd.infn.it:8443/ce-cream/services 2013-01-09 12:49:22,394 DEBUG REGISTRATION: Endpoint ID: cream-27.pd.infn.it_ComputingElement_org.glite.ce.ApplicationPublisher_1068561884; URL: gsiftp://cream-27.pd.infn.it:2811/opt/glite/var/info </verbatim> It is recommended to set back the logging level to error and restart the service. * stopping emier-serp will cause the entry to be deleted from the registry. -- Main.LisaZangrando - 2013-01-09
