Oracle RAC數據泵導出問題處理

1. 設置導出文件路徑

sqlplus / as sysdba

SQL> alter session set container=spdb1pdb;

SQL> create directory dump as '/tmp/dumpdata';

ORA-00955: name is already used by an existing object

處理方法：語句優化

SQL> CREATE OR REPLACE DIRECTORY dump as '/tmp/dumpdata';

 

2. 數據泵導出

1）expdp user/passwd@localhost:1521/spdb1pdb directory=dump dumpfile=dump191018.dump logfile=dump191018.log cluster=n;

UDE-12541: operation generated ORACLE error 12541

ORA-12541: TNS:no listener

處理方法：查看tnsnames.ora文件設置，因HOST設置為scan-ip，將localhost修改為scan-ip

expdp user/passwd@scan-ip:1521/spdb1pdb directory=dump dumpfile=dump191018.dump logfile=dump191018.log cluster=n;

 

2）expdp user/passwd@scan-ip:1521/spdb1pdb directory=dump dumpfile=dump191018.dump logfile=dump191018.log cluster=n;

ORA-39002：invalid operation

ORA-39070：Unable to open the log file

處理方法：查看導出文件路徑是否存在，或者更換路徑

SQL> select * from dba_directories where DIRECTORY_NAME='DUMP';

SQL> CREATE OR REPLACE DIRECTORY dump as '/tmp/dumpdata';
