Unable to register one extract,but the other twos are ok.

Question

Enviroment:
OS:Windows Server 2003 64bit
GG:
Oracle GoldenGate Command Interpreter for Oracle
Version 11.2.1.0.6 16211226 OGGCORE_11.2.1.0.6_PLATFORMS_130418.1829
Windows x64 (optimized), Oracle 11g on Apr 19 2013 17:38:40
There are three extract on the same server.Now I'd like to register for the three extracts.The other twos are ok,but there is a one extract,meet the below error message:
2013-12-22 21:43:50  ERROR   OGG-01755  Cannot register or unregister EXTRACT E_
ZF_K because of the following SQL error: OCI Error ORA-00001: unique constraint
(SYSTEM.LOGMNR_SESSION_UK1) violated
ORA-06512: at "SYS.DBMS_CAPTURE_ADM_INTERNAL", line 453
ORA-06512: at "SYS.DBMS_CAPTURE_ADM", line 289
ORA-06512: at line 1 (status = 1). See Extract user privileges in the Oracle Gol
denGate for Oracle Installation and Setup Guide.
What should I do?And I also want to know the detailed cause of this error.Thanks in acvance!

Hi,
Ongoing DDL operations on the Oracle database do not allow the PL/SQL PackageDBMS_CAPTURE_ADM.BUILD to build the LogMiner Data Dictionary, as part of the GGSCI REGISTER EXTRACT command.
NOTE: The DBMS_CAPTURE_ADM.BUILD procedure is the same as the DBMS_LOGMNR_D.BUILD procedure.
exec dbms_goldengate_auth.grant_admin_privilege('USER_NAME');
Connect to the Oracle database as SYSDBA  # sqlplus /nologin
SQL> connect / as sysdba
In the SYSDBA session, determine that there are no EXCLUSIVE DDL sessions.
(Summary)  SQL> select mode_held, count(*) from dba_ddl_locks group by mode_held;
(In detail)  SQL> select mode_held, name, type from dba_ddl_locks where mode_held = 'Exclusive' order by mode_held;
(To identify a specific user process)  select l.name, l.type, l.mode_held, s.sid, s.program, s.username, p.spid, p.pidfrom dba_ddl_locks l, v$session s, v$process p where l.mode_held = 'Exclusive' and l.session_id = s.sid and s.paddr = p.addr;
When there are no EXCLUSIVE mode DDL locks, re-run the GGSCI REGISTER EXTRACT command.
In case this is not working then try for following steps,
1. turn on sql trace
2. identify SQL and its bind variables:
declare
extract_name varchar2(100) := :1;
source_global_name varchar2(4000) := :2;
firstScn number := :3;
outbound_server_name varchar2(30);
outbound_capture_name varchar2(30);
capture_queue_name varchar2(30);
queue_table_name varchar2(30);
outbound_comment varchar2(125);
BEGIN
dbms_xstream_gg_adm.wait_for_inflight_txns := 'n';
dbms_xstream_gg_adm.synchronization := 'none';
dbms_xstream_gg_adm.is_goldengate := true; /* Construct the queue table name */
queue_table_name := SUBSTR('OGG$Q_TAB_' || extract_name, 1, 30); /* Construct the capture queue name */
capture_queue_name := SUBSTR('OGG$Q_' || extract_name, 1, 30); /* create capture queue */
dbms_streams_adm.set_up_queue(queue_table => queue_table_name, queue_name => capture_queue_name); /* Construct the outbound capture name */
outbound_capture_name := SUBSTR('OGG$CAP_' || extract_name, 1, 30); /* create capture specifying the first scn */ DBMS_XSTREAM_GG.SET_GG_SESSION();
dbms_capture_adm.create_capture(queue_name => capture_queue_name,
capture_name => outbound_capture_name,
first_scn => firstScn,
source_database => source_global_name); /* Construct the outbound server name */
outbound_server_name := SUBSTR('OGG$' || extract_name, 1, 30); /* Construct the comment assosciated with this outbound server */ outbound_comment := extract_name || ' GoldenGate Extract';
DBMS_XSTREAM_GG_ADM.ADD_OUTBOUND(server_name => outbound_server_name,
capture_name=> outbound_capture_name,
source_database=> source_global_name,
committed_data_only => FALSE,
wait_for_inflight_txns => 'N',
synchronization => 'NONE',
start_scn => firstScn,
comment => outbound_comment);
DBMS_XSTREAM_GG.SET_GG_SESSION(FALSE);
END;
3. run the sql manually under sqlplus.
it hits:
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-01502: index 'SYS.I_WRI$_OPTSTAT_TAB_OBJ#_ST' or partition of such index is
in unusable state
ORA-06512: at "SYS.DBMS_STREAMS_ADM", line 746
ORA-06512: at line 16
4.
SQL> select owner,status from dba_indexes where index_name='I_WRI$_OPTSTAT_TAB_OBJ#_ST';
OWNER STATUS
SYS UNUSABLE
5.rebuild th index, but it did not help:
alter index I_WRI$_OPTSTAT_H_OBJ#_ICOL#_ST rebuild;
6. drop and recreate the index. Then the extract can be registered
