The original tool has been completely re-designed in terms of database backend and components, adding support for submission to multiple backends, including the original WMS and the new Panda modules. The database engine has been changed from plain MySQL to Galera/Percona and the table structure has been optimized to allow a full High-Availability (HA) solution over WAN. The servlets, running on each frontend, have been also decoupled from local settings, to allow an easy scalability of the system, including the possibility of an HA system with multiple sites. The clients can also be run in multiple copies and in different geographical locations, and take care of sending the installation and validation jobs to the target Grid or Cloud sites. Moreover, the Installation DB is used as source of parameters by the automatic agents running in CVMFS, in order to install the software and distribute it to the sites. The system is in production for ATLAS since 2013, having as main sites in HA the INFN Roma T2 and CERN AI. The LJSFi2 engine is directly interfacing with Panda for the Job Management, AGIS for the site parameter configurations, and CVMFS for both core components and the installation of the software itself. LJSFi2 is also able to use other plugins, and is essentially VO-agnostic, so can be directly used and extended to cope with the requirements of any Grid or Cloud enabled VO. In this work we'll present the architecture, performance, status and possible evolutions to the system for the LHC Run2 and beyond. 002015209 540__ $$3publication$$aCC-BY-3.0 002015209 540__ $$3publication$$aCC-BY-3.0 002015209 542__ $$3publication$$dThe Author(s)$$g2015 002015209 542__ $$3publication$$dThe Author(s)$$g2015 002015209 594__ $$aPROC 002015209 595__ $$aCERN CDS-Invenio WebSubmit 002015209 595__ $$aINSPIRE-PUBL-2015 002015209 65017 $$2SzGeCERN$$aParticle Physics - Experiment 002015209 65027 $$2SzGeCERN$$aSoftware 002015209 693__ $$aCERN LHC$$eATLAS 002015209 690C_ $$aCERN 002015209 690C_ $$aINTNOTE 002015209 690C_ $$aPUBLATLAS 002015209 690C_ $$aINTNOTEATLASPUBL 002015209 690C_ $$aARTICLE 002015209 700__ $$0AUTHOR|(SzGeCERN)648549$$0AUTHOR|(INSPIRE)INSPIRE-00216496$$aMaeno Kataoka, [email protected]$$uThe University of Texas at Arlington 002015209 700__ $$0AUTHOR|(SzGeCERN)679537$$0AUTHOR|(INSPIRE)INSPIRE-00237353$$aSanchez, [email protected]$$uINFN Napoli and Universita' di Napoli, Dipartimento di Fisica, Napoli 002015209 700__ $$0AUTHOR|(INSPIRE)INSPIRE-00340451$$0AUTHOR|(SzGeCERN)493089$$aSmirnov, [email protected]$$uNorthern Illinois University 002015209 710__ $$5PH-EP 002015209 773__ $$c062012$$n6$$pJ.
