and File 2 contains :-

emcas_bdl_migrate=2 emcas_biaas_dev=63 emcas_brs_ba=430 emcas_cc_analytics=2231 emcas_clm_reporting=16 emcas_collab_xsat=6241 emcas_cpsd_cee=11 emcas_cpsd_hcp=0 emcas_e2ep_ba=187 emcas_edservices_bi=955 emcas_edservices_dev=374 emcas_elms_analytics=0 emcas_engr_clm=3 emcas_engr_scaleio=0 emcas_engr_usd=2669 emcas_engr_xio=340 emcas_fin_bi=333 emcas_fin_drr=5528
