ORA-26723: user "STRMADM1" requires the role "DBA"

Question

I granted dba to the streams adm user but sqlplus still complains:
sqlplus / as sysdba
SQL> grant dba to strmadm1;
Grant succeeded.
SQL> conn strmadm1/xxxxx
Connected.
SQL> BEGIN add_capture_rules('TABLE1','capture_db1','strmadm1','emsuser'); END;
2 /
BEGIN add_capture_rules('TABLE1','capture_db1','strmadm1','emsuser'); END;
ERROR at line 1:
ORA-26723: user "STRMADM1" requires the role "DBA"
ORA-06512: at "SYS.DBMS_STREAMS_ADM", line 372

ORA-06512: at "STRMADM1.ADD_CAPTURE_RULES", line 14
ORA-06512: at line 1
where add_capture_rules is simply a wraper of DBMS_STREAMS_ADM.ADD_TABLE_RULES:
CREATE OR REPLACE PROCEDURE ADD_CAPTURE_RULES(
p_table_name IN VARCHAR2,
p_streams_name IN VARCHAR2,
p_strmadm IN VARCHAR2,
emsuser IN VARCHAR2)
IS
p_queue_name VARCHAR2(100) := p_strmadm || '.' || emsuser || '_queue';
BEGIN
dbms_output.put_line('queue_name=' || p_queue_name);
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => emsuser || '.' || p_table_name,
streams_type => 'capture',
streams_name => p_streams_name,
queue_name => p_queue_name,
include_dml => true,
include_ddl => true);
END;
Why? Please help!

Answer 1

The reason is that you didn't read the docs. You just made the assumption that the DBA role contained the required privileges: It does not.
I could easily point you in the right direction, and perhaps I should, but given that you didn't post your question to the Streams forum where it would have been on topic, and given that you obviously have not read the docs, I'm going into my professional role, professor, and suggest you do your homework and learn more than just the one quick answer.
