After moving our 10g database to 11g with golden gate...our developers were complaining about ORA-12991: column is referenced in a multi-column constraint...This problem is related to enabling Supplemental Logging with "ALTER DATABASE ADD SUPPLEMENTAL LOG DATA" , when u try to drop a column...First of all u have to find what log_group_name causes the problem...
SQL> select log_group_name from dba_log_groups where table_name = 'TABLE_NAME' ;
LOG_GROUP_NAME
============================
GGS_DROP_COLS_24242
Then drop it;
SQL> alter table table_name drop supplemental log group GGS_DROP_COLS_24242;
table altered.
