IMPDP Fails With ORA-39180: "Unable To Encrypt ENCRYPTION_PASSWORD" After Switching TDE Wallet

(Doc ID 436876.1)

Oracle Server - Enterprise Edition - Version to [Release 10.2]
Information in this document applies to any platform.


When using impdp to import a datapump export dump file that has a table with an encrypted column in it you get  errors the same as in the following example:


$ impdp system/manager directory=test dumpfile=TDE.DMP encryption_password="thesecret" nologfile=y full=y

Import: Release - Production on Wednesday, 20 June, 2007 10:05:10

Connected to: Oracle Database 10g Enterprise Edition Release - Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining options
ORA-39001: invalid argument value
ORA-39180: unable to encrypt ENCRYPTION_PASSWORD
ORA-28362: master key not found

You have verified the wallet is open and TDE encryption works normally, for example you can execute the command: create table system.tde_test(test number encrypt);


The impdp utility was used before on this database and after that the wallet was regenerated.

It is important to only use the workaround / solution if this can be confirmed!
