How to troubleshot "ORA-29106: Cannot import PKCS #12 wallet."

 [donghua@myhost ~]$ sql user/pass@db1_ssl

SQLcl: Release 21.2 Production on Tue Aug 17 03:01:21 2021

Copyright (c) 1982, 2021, Oracle.  All rights reserved.

  USER          = 

  URL           = jdbc:oracle:oci8:@db1_ssl

  Error Message = ORA-29106: Cannot import PKCS #12 wallet.

  USER          = 

  URL           = jdbc:oracle:thin:@db1_ssl

  Error Message = IO Error: Unknown host specified


Make sure that wallet is created with -auto_login instead of -auto_login_local

orapki wallet create -wallet "/u01/app/oracle/wallet" -pwd Welcome123 -auto_login

 

1. Use -auto_login_local option to create an auto login wallet (cwallet.sso) that is local to both the computer on which it is created and the user who created it.
2. Make sure "chmod 644 /u01/app/oracle/wallet/*" if you intend to share the wallet to other users

How to troubleshoot "ORA-28367: wallet does not exist"

There are multiple ways to specify Oracle Wallet locations. Make sure you use "select wrl_parameter from v$encryption_wallet" to find out where the Oracle instance "think" the location should be.


Method 1: set Wallet location using "wallet_root" initialisation parameter (In this case, don't not need to specify keystone location in the SQL command lines)


SQL> alter system set wallet_root='/u01/app/oracle/admin/orcl/wallet' scope=spfile;

SQL> shutdown immediate

SQL> startup

SQL> alter system set tde_configuration='keystore_configuration=file' scope=both;


SQL> select con_id, keystore_mode from v$encryption_wallet;

    CON_ID KEYSTORE

---------- --------

     1 NONE

     2 UNITED

     3 UNITED

SQL> administer key management create keystore identified by Welcome123;

SQL> administer key management create auto_login keystore from keystore identified by Welcome123;



SQL> ! ls -l /u01/app/oracle/admin/orcl/wallet/tde/

total 8

-rw------- 1 oracle oinstall 2600 Aug 16 09:26 cwallet.sso

Method 2: Set Wallet location in $ORACLE_HOME/network/admin/sqlnet.ora using "ENCRYPTION_WALLET_LOCATION" or "WALLET_LOCATION" (In this case, please specify keystone location in the SQL command lines)

Oracle 21c on Linux Silent installation

Oracle 21c for Linux platform is available today. You can download from here: https://www.oracle.com/database/technologies/oracle-database-software-downloads.html


To keep the information brief, I will just post commands I used for 21c installation. You can always reference to official installation guide and other posts for more information:


Take note "-sampleSchema true" is not longer supported in 21c.
>> [FATAL] [DBT-12513] Sample schema is not supported in oracle home version 21.0.0.0.0.

And OracleHome is ReadOnly Home

[oracle@ol8 bin]$ orabasehome

SSLAuthentication with Oracle database in Summary (Mutual authentication, 2 way authentication, certificate login)

 Setup steps, please reference doc here: https://docs.oracle.com/en-us/iaas/data-safe/doc/create-self-signed-certificate-db-system-client-authentication-enabled.html

Scenario 1: Client doesn't import Server certificate/CA and Server doesn't import client certificate/CA.

(Regardless SSL_CLIENT_AUTHENTICATION=TRUE or FALSE)

Result: connection failed

Message: ORA-29024: Certificate validation failure

Scenario 2: Client import Server certificate/CA and Server doesn't import client certificate/CA.

2.1 Testing with SSL_CLIENT_AUTHENTICATION = FALSE on server

Result: Success

2.2 Testing with SSL_CLIENT_AUTHENTICATION = TRUE on server

Result: Connection failed

Message: ORA-28860: Fatal SSL error

Message in Listener log:

2021-08-02T04:50:44.966526+00:00
02-AUG-2021 04:50:44 * (ADDRESS=(PROTOCOL=tcps)(HOST=10.2.0.80)(PORT=9782)) * <unknown connect data> * 542
TNS-00542: SSL Handshake failed
 TNS-12560: TNS:protocol adapter error

Scenario 3: Client import Server certificate/CA and Server import client certificate/CA.

(Regardless SSL_CLIENT_AUTHENTICATION=TRUE or FALSE)

Result: OK

Take note that 2-way SSL verification only happens if both client and server setting are true.

Scenario 4: Built-on Scenario 3, Authenticate user using SSL Certification
