I have been recently able to make several migration tests from On-Premises to Exadata, and during some of my tests I faced a PDB_PLUG_IN_VIOLATIONS with cause been “Wallet Key Needed” when converting a migrated Non-CDB to PDB.<\/p>\n\n\nRead more: Migration from Non-CDB to Multitenant : Wallet Key Needed<\/span><\/a>\n\n\n

Explanation<\/h2>\n\n\n\n

This violation comes from the fact that the source Non-CDB database migrated on the Exadata from On-Premises was encrypted. The message is clear, the source wallet needs to be exported and imported in the new PDB after having run noncdb_to_pdb.sql script.<\/p>\n\n\n\n

\nSQL> select name, cause, type, message, status from PDB_PLUG_IN_VIOLATIONS where type = 'ERROR' and status  'RESOLVED';\n\nNAME                 CAUSE                                                            TYPE      MESSAGE                                                                STATUS\n-------------------- ---------------------------------------------------------------- --------- ---------------------------------------------------------------------- ---------\nPDB_NAME       Wallet Key Needed                                                ERROR     PDB needs to import keys from source.                                  PENDING\n<\/pre>\n<\/br>\n\n\n\n
Export wallet from the Non-CDB<\/h2>\n\n\n\n
Connecting to the Non-CDB source database, I can check the wallet configuration.<\/p>\n\n\n\n
\nSQL> select WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\nWRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n------------------------------------------------------------ -------------------- -------------------- ------------------------------\n\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/wallet_root\/tde\/             FILE                 AUTOLOGIN            OPEN\n<\/pre>\n<\/br>\n\n\n\n
So I tried to export my wallet.<\/p>\n\n\n\n
\nSQL> administer key management\n  2  export encryption keys with secret \"\"\n  3  to '\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/DB_NAME_to_PDB_wallet.p12'\n  4  identified by \"************\"\n  5  \/\nadminister key management\n*\nERROR at line 1:\nORA-28417: password-based keystore is not open\n<\/pre>\n<\/br>\n\n\n\n
But I faced following error:<\/p>\n\n\n\n
ORA-28417: password-based keystore is not open<\/code><\/pre>\n\n\n\n
This is because my wallet is opened in autologin and not as password file.<\/p>\n\n\n\n
So let’s close it and open it as password file.<\/p>\n\n\n\n
To do so it should be sufficient to run a keystore close before running a keystore open.<\/p>\n\n\n\n
\nSQL> administer key management set keystore close;\n\nkeystore altered.\n<\/pre>\n<\/br>\n\n\n\n
I was also trying moving the autologin cwallet.sso file and see how that works.<\/p>\n\n\n\n
I first closed my Source Non-CDB database.<\/p>\n\n\n\n
\nSQL> shutdown immediate\nDatabase closed.\nDatabase dismounted.\nORACLE instance shut down.\n<\/pre>\n<\/br>\n\n\n\n
Then I renamed the cwallet.sso file.<\/p>\n\n\n\n
\noracle@ExaCC-cl01n1:\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/wallet_root\/tde\/ [PDB_NAME (CDB$ROOT)] mv cwallet.sso cwallet.sso.no_auto\n<\/pre>\n<\/br>\n\n\n\n
I started again the database.<\/p>\n\n\n\n

I checked the wallet type and its status.<\/p>\n\n\n\n
\nSQL> select WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\nWRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n------------------------------------------------------------ -------------------- -------------------- ------------------------------\n\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/wallet_root\/tde\/             FILE                 UNKNOWN              CLOSED\n<\/pre>\n<\/br>\n\n\n\n
As expected it was closed. I opened it.<\/p>\n\n\n\n
\nSQL> ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY \"*****************\";\n\nkeystore altered.\n<\/pre>\n<\/br>\n\n\n\n
Checked the wallet status again.<\/p>\n\n\n\n
\nSQL> select WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\nWRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n------------------------------------------------------------ -------------------- -------------------- ------------------------------\n\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/wallet_root\/tde\/             FILE                 PASSWORD             OPEN\n<\/pre>\n<\/br>\n\n\n\n\n
Now the wallet is opened with password as needed. And I tried to export the wallet again.<\/p>\n\n\n\n
\nSQL> administer key management\n  2  export encryption keys with secret \"\"\n  3  to '\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/bak_DB_NAME_to_PDB_wallet.p12'\n  4  identified by \"************\"\n  5  \/\nadminister key management\n*\nERROR at line 1:\nORA-46644: creation or open of file to store the exported keys failed\n<\/pre>\n<\/br>\n\n\n\n
I got a new error:<\/p>\n\n\n\n
ORA-46644: creation or open of file to store the exported keys failed<\/code><\/pre>\n\n\n\n
This might be due to user permissions to write in the folder. Let’s save it in \/tmp.<\/p>\n\n\n\n
\nSQL> administer key management\n  2  export encryption keys with secret \"\"\n  3  to '\/tmp\/DB_NAME.p12'\n  4  identified by \"************\"\n  5  \/\n\nkeystore altered.\n<\/pre>\n<\/br>\n\n\n\n
This time it worked.<\/p>\n\n\n\n
I shutdown the database again.<\/p>\n\n\n\n
\nSQL> shutdown immediate\nDatabase closed.\nDatabase dismounted.\nORACLE instance shut down.\n<\/pre>\n<\/br>\n\n\n\n
Moved the autologin wallet file back.<\/p>\n\n\n\n

And checked that my wallet has been automatically opened again.<\/p>\n\n\n\n
\nSQL> select WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\nWRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n------------------------------------------------------------ -------------------- -------------------- ------------------------------\n\/var\/opt\/oracle\/dbaas_acfs\/DB_NAME\/wallet_root\/tde\/             FILE                 AUTOLOGIN            OPEN\n<\/pre>\n<\/br>\n\n\n\n
Import the wallet in the PDB<\/h2>\n\n\n\n
Now we need to import the wallet in the PDB<\/p>\n\n\n\n
I connected to the PDB.<\/p>\n\n\n\n
\nSQL> alter session set container=PDB_NAME;\n\nSession altered.\n\nSQL> show pdbs\n\n    CON_ID CON_NAME                       OPEN MODE  RESTRICTED\n---------- ------------------------------ ---------- ----------\n         4 PDB_NAME                 READ WRITE YES\n<\/pre>\n<\/br>\n\n\n\n
Check the wallet status.<\/p>\n\n\n\n
\nSQL> select WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\nWRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n------------------------------------------------------------ -------------------- -------------------- ------------------------------\n                                                             FILE                 AUTOLOGIN            OPEN_NO_MASTER_KEY\n<\/pre>\n<\/br>\n\n\n\n
I tried to import the wallet, expected it to fail as the wallet is with a autologin type.<\/p>\n\n\n\n
\nSQL> administer key management\n  2  import encryption keys with secret \"\"\n  3  from '\/tmp\/DB_NAME.p12'\n  4  identified by \"**************\"\n  5  with backup USING 'pre-import-PDB_NAME'\n  6  \/\nadminister key management\n*\nERROR at line 1:\nORA-28417: password-based keystore is not open\n<\/pre>\n<\/br>\n\n\n\n
So I need to connect to the CDB$ROOT to open the wallet with the password. I checked and could see that the wallet is opened automatically for the CDB$ROOT and all PDB. The CDB$ROOT wallet is shared with the PDB.<\/p>\n\n\n\n
\nSQL> alter session set container=cdb$root;\n\nSession altered.\n\nSQL> select CON_ID, WRL_PARAMETER, WRL_TYPE,WALLET_TYPE, status from V$ENCRYPTION_WALLET;\n\n    CON_ID WRL_PARAMETER                                                WRL_TYPE             WALLET_TYPE          STATUS\n---------- ------------------------------------------------------------ -------------------- -------------------- ------------------------------\n         1 \/var\/opt\/oracle\/dbaas_acfs\/CDB_NAME\/wallet_root\/tde\/         FILE                 AUTOLOGIN            OPEN\n         2                                                              FILE                 AUTOLOGIN            OPEN\n         3                                                              FILE                 AUTOLOGIN            OPEN\n         4                                                              FILE                 AUTOLOGIN            OPEN_NO_MASTER_KEY\n<\/pre>\n<\/br>\n\n\n\n
So I closed the wallet, opened it with password and check its status.<\/p>\n\n\n\n

I connected to the PDB and tried to import the wallet.<\/p>\n\n\n\n

Which was not working as expected as the wallet is closed for the PDB. So I opened it with password.<\/p>\n\n\n\n

I connected to the CDB$ROOT again. I checked the wallet status and could see it is open with password for the CDB$ROOT and new PDB and closed for the others, which might impact them. Not a problem in my case, as all here, is only used for tests for migration.<\/p>\n\n\n\n

I restarted the PDBs and could see that the wallet key needed pdb violations has been resolved.<\/p>\n\n\n\n
To wrap up<\/h2>\n\n\n\n
Converting an encrypted Non-CDB to PDB will require the wallet, containing the master key needed to encrypt\/decrypt, to be exported from the source database and imported to the new PDB.<\/p>\n\n\n\n
Last but not least, for me it was a lab, so no risk, but it is important to mention than we need to work carefully with the wallet and have good backup because loosing a wallet can be dramatical and can result in no way to access your data any more.
