Post faces ORA-14148 by adding column with the default value and changing primary key for added column like the below sql.
< Example >
ALTER TABLE sptest ADD ( col1 CHAR(1) DEFAULT 'A' ) ;
Alter table sptest drop constraint pk_constraint_xxx;
Alter table sptest add constraint pk_constraint_xxx primary key(col1);
WORKAROUND:
Re-activate with same config
