Purpose: How to Configure Oracle Client with multiple Oracle wallets/locations for different Autonomous Databases and connect with SQL*Plus from your PC.
Environment:
Database: Oracle Cloud, 19c, Autonomous Databases (ADB)
Client: Oracle 12c 64Bit Client from my Windows PC
Configuration Files: SQLNET.ORA and TNSNAMES.ORA
Step # 1: I have already have two ADBs (names: CWTP and CWDW) in Oracle Cloud and downloaded Oracle wallets (zip files and extracted) for each of those databases and placed at two different folders:-
C:\Oracle12cR2_64Bit_CL\wallet\cwdw
C:\Oracle12cR2_64Bit_CL\wallet\cwtp
Step # 2: From the extracted zip files (wallets), I copied and pasted contents of TNS entries from the sqlnet.ora and tnsnames.ora files that came along with the wallets into the SQLNET.ORA and TNSNAMES.ORA files ($ORACLE_HOME\Network\Admin) that's used by my Oracle client, which looked as follows:-
SQLNET.ORA
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
# WALLET_LOCATION = (SOURCE = (METHOD = file) (METHOD_DATA = (DIRECTORY=C:\\Oracle12cR2_64Bit_DB\\wallet\\cwdw)))
SSL_SERVER_DN_MATCH=yes
As you notice above, I commented out WALLET_LOCATION parameter, which is configured in the TNSNAMES.ORA file
Step # 3: TNSNAMES.ORA
cwtp_low = (description= (retry_count=20)(retry_delay=3)(address=(protocol=tcps)(port=1533)(host=adb.au-xxxxxxx-1.oraclecloud.com))(connect_data=(service_name=xxxxxcwtp_low.atp.oraclecloud.com))(security=(my_wallet_directory = "C:\\Oracle12cR2_64Bit_CL\\wallet\\cwtp")(ssl_server_cert_dn="CN=xxxxx.oraclecloud.com,OU=Oracle BMCS US,O=Oracle Corporation,L=Redwood City,ST=California,C=US")))
cwdw_low = (description= (retry_count=20)(retry_delay=3)(address=(protocol=tcps)(port=1533)(host=adb.au-xxxxxxx-1.oraclecloud.com))(connect_data=(service_name=xxxxxcwdw_low.adwc.oraclecloud.com))(security=(my_wallet_directory = "C:\\Oracle12cR2_64Bit_CL\\wallet\\cwdw")(ssl_server_cert_dn="CN=xxxxx.oraclecloud.com,OU=Oracle BMCS US,O=Oracle Corporation,L=Redwood City,ST=California,C=US")))
As you notice in the TNSNAMES.ORA file, I have added MY_WALLET_DIRECTORY (within the SECURITY parameter) to include the wallet location for each TNS Aliases. S
Step # 4: Test - Here are my tests connecting to the ADBs using SQL*Plus from my PC:-
Let me know how it works for you and also if there are any other options available to configure multiple wallets / locations for Oracle client.
