IMPDP Fails With ORA-39180: "Unable To Encrypt ENCRYPTION_PASSWORD" After Switching TDE Wallet (Doc ID 436876.1)

Last updated on NOVEMBER 03, 2015

Applies to:

Oracle Server - Enterprise Edition - Version 10.2.0.1 to 10.2.0.4 [Release 10.2]
Information in this document applies to any platform.

Symptoms

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 10.2.0.3.0 - Production on Wednesday, 20 June, 2007 10:05:10

Copyright (c) 2003, 2005, Oracle. All rights reserved.

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 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);

Changes

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!
