Simple stuff really, but here’s how…
Open a terminal window, set the ORACLE_HOME environment variable as appropriate, and start the utility:
export ORACLE_HOME=/u01/app/oracle/product/11.2.0 cd $ORACLE_HOME/bin owm &
When the GUI appears, if the default wallet path is not being used, click ‘Open Wallet’ from the sidebar then specify the wallet path, for example:
/home/oracle/secure_wallet
…then hit OK and enter the relevant password.
Click Operations > Import Trusted Certificate from the top menu bar.
The Import Trusted Certificate message is displayed. You now have the option of importing a certificate file, or pasting the contents (base64 formatted)…
Select a file that contains the certificate
Enter the path or folder name of the trusted certificate location and file, for example: /home/oracle/new_ssl.cert
Click OK.
Paste the certificate
Another Import Trusted Certificate dialog panel appears with the following message:
“Please provide a base64 format certificate and paste it below.”
Copy the certificate text (from an email or file received) including the lines ‘Begin Certificate’ and ‘End Certificate’.
Paste the certificate into the window, and click OK.
A message at the bottom of the window informs you that the trusted certificate was successfully imported into the wallet. Click OK to dismiss the dialog panel. You are returned to the Oracle Wallet Manager main panel, and the trusted certificate is displayed at the bottom of the Trusted Certificates tree.
Make sure you’ve saved your wallet changes by clicking the ‘Save Wallet’ from the sidebar, then exit….simples!
