POMS

Introduction

The Production Operations Management Service (POMS) is a computing division tool that helps users to run large and complex grid campaigns. It provides

• control scripts and GUI interface
• chaining of multiple stages of a grid campaign
• re-submission of failed jobs
• analysis of logs and database entries for results

Currently (8/2021), we are only using POMS for Production as a test. Users can use Mu2e tools

project-py is s python scripts which provides a command line interface.

UconDB

mu2e_ucon_prod - created 11/2021 to help with MDC2020

• database mu2e_ucon_prod owned by nologin role mu2e_ucon_prod;
• Kerberos-authenticated roles: brownd kutschke srsoleti
• md5 authenticated role 'mu2e_ucon_web' (for POMS)
• port is 5458 (on ifdbprod/ifdb08)

FCL files are saved to the UconDB in dedicated folders. It's not possible to use dots in the name of the database folders, so we replace with underscores, as in: https://dbdata0vm.fnal.gov:9443/mu2e_ucondb_prod/app/UI/folder?folder=cnf_mu2e_pot_db_test_v12_fcl

The POMS FCL stages take care of creating the folders and saving the FCL files. The SAM location of the files stored in the database looks like this:

$ samweb locate-file cnf.mu2e.POT.db_test_v12.001201_00000001.fcl
dbdata0vm.fnal.gov:/mu2e_ucondb_prod/app/data/cnf_mu2e_POT_db_test_v12_fcl
