SQL*PLUS

In this post I will describe how to connect to Autonomous Database using SQL*PLUS

Steps: Connecting to Autonomous Database using SQL*PLUS

To connect to Autonomous database we need to download the client credentials wallet

1. From Autonomous database details page: Click on DB Connection

2. Select Download Wallet

3. Enter the credentials to protect wallet and Click on Download, once downloaded close the window.

Connect using SQL*PLUS

1. Unzip the credentials on the machine where Oracle client is installed

[oracle@ol7-db wallet]$ pwd
/u01/wallet
[oracle@ol7-db wallet]$ ls -ltrh
total 24K
-rw-r--r--. 1 oracle oinstall 21K Mar 31 23:13 Wallet_orbgadb.zip
[oracle@ol7-db wallet]$ unzip Wallet_orbgadb.zip
Archive:  Wallet_orbgadb.zip
  inflating: README
  inflating: cwallet.sso
  inflating: tnsnames.ora
  inflating: truststore.jks
  inflating: ojdbc.properties
  inflating: sqlnet.ora
  inflating: ewallet.p12
  inflating: keystore.jks
[oracle@ol7-db wallet]$

2. Edit the sqlnet.ora and specify the correct wallet location
In my case Wallet unzipped location is : /u01/wallet

WALLET_LOCATION = (SOURCE = (METHOD = file) (METHOD_DATA = (DIRECTORY="?/network/admin")))
SSL_SERVER_DN_MATCH=yes

To

WALLET_LOCATION = (SOURCE = (METHOD = file) (METHOD_DATA = (DIRECTORY="/u01/wallet")))
SSL_SERVER_DN_MATCH=yes

3. Set the TNS environment variable and verify the connection

export TNS_ADMIN=/u01/wallet
tnsping orbgadb_low
sqlplus admin@orbgadb_low

Output:

[oracle@ol7-db wallet]$ export TNS_ADMIN=/u01/wallet
[oracle@ol7-db wallet]$
[oracle@ol7-db wallet]$ tnsping orbgadb_low
