FAQ
Question 1: An error is reported by impdp or expdp, and the error message is as follows.
symptoms
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
solution
1. First delete the previously created backup directory
SQL> drop directory exp
2. Recreate a new backup directory
SQL> create or replace directory erp as '/u01/import ';
Directory created.
SQL> grant read,write on directory kmdata_exp to public ;
3. Authorize the folder
chown -R oracle:oinstall /u01/import
4. Retest
Problem 2: There are version differences in the database
symptoms
There is no effect when importing from a higher version to a lower version. But when a lower version is imported into a higher version, an error message will appear
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-39142: incompatible version number 5.1 in dump file "/u01/import/expdp_20201117.dmp"
solution
When exporting the specified version expdp, you need to specify the version of the target database. The following method
expdp erp/123456 directory=erp dumpfile=expdp_20201117.dmp logfile=expdp_log_20201117.log schemas=erp version=12.2.0.1.0
- Just re-import
