I am trying to apply the April 2018 OJVM patch on and Oracle 12.1.2 RAC environment. The patch applies OK. but when I get to the startup upgrade step to do the datapatch the startup fails with the following error:
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: '/shared_oradata/MAFPS/system01.dbf'
Post-install datapatch
srvctl stop database -d spfamdb
SQL> startup
SQL> alter system set cluster_database=false scope=spfile;
SQL> quit
