Oracle RAC数据泵导出问题处理

1. 设置导出文件路径

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

处理方法：语句优化

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

2. 数据泵导出

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

处理方法：查看tnsnames.ora文件设置，因HOST设置为scan-ip，将localhost修改为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

处理方法：查看导出文件路径是否存在，或者更换路径

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

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