McM Scripts

Repository for using McM scripts and example scripts

Basic info

• Link to McM: https://cms-pdmv.cern.ch/mcm/

• McM Rest API: https://cms-pdmv.cern.ch/mcm/restapi

• For most actions you will NEED to have a valid CERN SSO cookie

• Public APIs do not require a cookie. Index of public API: https://cms-pdmv.cern.ch/mcm/public/restapi/

CERN SSO cookie

• Use cern-get-sso-cookie command line tool to generate it:

  • cern-get-sso-cookie --url https://cms-pdmv-dev.cern.ch/mcm/ -o dev-cookie.txt

  • cern-get-sso-cookie --url https://cms-pdmv.cern.ch/mcm/ -o prod-cookie.txt

• cern-get-sso-cookie is already available in lxplus nodes

• It expires after ~10 hours, so be sure to regenerate it

• Dev cookie is valid only for dev environment and production cookie is valid only for production environment

Priority change

• If you want to use priority changing scripts or do anything else related to cmsweb, you'll have to use voms-proxy:

  • voms-proxy-init -voms cms

  • export X509_USER_PROXY=$(voms-proxy-info --path)
