If Schema test fails during domain creation, you need to update that particular record in the database table.
connect sys/welcome1 as sysdba;
grant DBA to DEV_MDS;
update schema_version_registry set version=’11.1.1.7.0′ where owner= ‘DEV_MDS’;
update schema_version_registry set version=’11.1.1.7.0′ where owner= ‘DEV_SOAINFRA’;
commit;
Hope this helps!
