db_recovery_file_dest_size of 81920 MB is 0.00% used. This is a
user-specified limit on the amount of space that will be used by this
database for recovery-related files, and does not reflect the amount of
space available in the underlying filesystem or ASM diskgroup.

查了一下metalink官方字符，发现官方文档有这方面的资料，出现这个问题是因为“ A datapump queue is invalid or it doesn't exist. The problem occurs during the buffered queue initialization.”，详情如下所示：
“Errors ORA-31623 And ORA-600 [kwqbgqc: bad state] During DataPump Export Or Import (文档 ID 754401.1)”原文如下：
APPLIES TO:

At the same time an ORA-600 error is reported an the alert log:
Mon Nov 28 13:06:39 2011
Errors in file /production/ora1/DUPDWH/var/DUPDWH/admin/udump/dupdwh_ora_16238.trc:

CAUSE
A datapump queue is invalid or it doesn't exist.?
The problem occurs during the buffered queue initialization.
SOLUTION
To recreate the failing queue, follow the steps from?
Note 754401.1 - ORA-31623 and ORA-600 [kwqbgqc: bad state] During an Export or Import with DataPump
NOTE:403036.1 - ORA-00600: [Kwqbgqc: Bad State], [1], [1] reported on Enqueue of BUFFERED message to a single or multiple consumer queue

"Errors ORA-31623 And ORA-600 [kwqbgqc: bad state] During DataPump Export Or Import (文档 ID 754401.1)"原文如下所示： |
APPLIES TO:
Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Information in this document applies to any platform.
An export or import operation using DataPump fails with the following errors:
UDI-00008: operation generated ORACLE error 31623
ORA-31623: a job is not attached to this session via the specified handle
ORA-06512: at "SYS.DBMS_DATAPUMP", line 2772
ORA-06512: at "SYS.DBMS_DATAPUMP", line 3886
ORA-06512: at line 1
and the alert log file of the database shows the error:
ORA-00600: internal error code, arguments: [kwqbgqc: bad state], [1], [1], [], [], [], [], []
A DataPump queue is invalid in data dictionary. This can happen after reruning the catpatch.sql or utlrp.sql scripts.
1. Shutdown the database cleanly:
SQL> connect / as sysdba
SQL> shutdown immediate
SQL> startup restrict
2. Drop the queue table.
SQL> exec dbms_aqadm.drop_queue_table (queue_table => 'SYS.KUPC$DATAPUMP_QUETAB', force => TRUE);
NOTE:
- If the ORA-4020 error is reported, then wait some minutes and try again
- If an ORA-24* error is reported, then it could be necessary to perform a manual cleanup. To perform this, contact with a Support Engineer.
3. Recreate the queue
The SQL is in the?Note.361025.1 or you can pull it from the catdpb.sql script in $ORACLE_HOME/rdbms/admin directory.
-- Create our queue table.
BEGIN
dbms_aqadm.create_queue_table (queue_table => 'SYS.KUPC$DATAPUMP_QUETAB',
multiple_consumers => TRUE,
queue_payload_type => 'SYS.KUPC$_MESSAGE',
comment => 'DataPump Queue Table',
compatible => '8.1.3');
EXCEPTION
WHEN OTHERS THEN
IF SQLCODE = -24001 THEN NULL;
ELSE RAISE;
END IF;
END;
/
4. Run utlrp.sql to recompile all the database objects.
5. Retry the DataPump operation
测试验证，使用expdp导出时，确实会遇到ORA-06512错误，具体如下所示：
$ expdp system/xxx DIRECTORY=DUMP_DIR LOGFILE=expdp.log DUMPFILE=test.dmp TABLES=xxxx.xxxx
