Oracle manually executed the export report ora-31634, ora-31664
. The backup task of oracle was deployed on the server through a scheduled task. Recently, it was found that a table space was not backed up successfully. After manual execution, an error was reported. The Baidu search results are as follows
ORA-31634: job already exists (JOB already exists)
ORA-31664: unable to construct unique job name when defaulted (using the default method, can not create a unique JOB name)
Solution:
The first step: query and generate SQL statements to clean up DBA_DATAPUMP_JOBS
1 select 'drop table ' || owner_name || '.' || job_name || ';'
2 from dba_datapump_jobs
3 where state = 'NOT RUNNING'
Copy the generated processing SQL statement and clean up the table DBA_DATAPUMP_JOBS. The example sentences are as follows:
...............
drop table neands3.SYS_EXPORT_SCHEMA_06;
drop table neands3.SYS_EXPORT_SCHEMA_40;
...............
Step 2: After cleaning up, check again to confirm whether DBA_DATAPUMP_JOBS has been cleaned up
1 SELECT owner_name, job_name, operation, job_mode,
2 state, attached_sessions
3 FROM dba_datapump_jobs
4 ORDER BY 1,2;
After the first step is executed, the backup is ready, so the third step is not executed.
Step 3: If the cleanup fails, execute the following statement for processing
EXEC DBMS_DATAPUMP.STOP_JOB(DBMS_DATAPUMP_ATTACH(‘SYS_EXPORT_SCHEMA_02’,’OAK’));Actually used
