Hi Community,

Hope you are all doing good.

I tried below steps in my DB but final SQL giving me one exception, could anyone please have a look and suggest if something I missed.

/*
-- I exported all certificates from https://gb.redhat.com/ which I further added in wallet. (below steps)
*/
orapki wallet create -wallet /home/oracle/wlt_vip -pwd ***** -auto_login
orapki wallet add -wallet /home/oracle/wlt_vip -cert /home/oracle/RH_1.cer -trusted_cert -pwd *****
orapki wallet add -wallet /home/oracle/wlt_vip -cert /home/oracle/RH_2.cer -trusted_cert -pwd *****

EXEC UTL_HTTP.set_wallet('file:/home/oracle/wlt_vip', '*****');

SELECT utl_http.request('https://gb.redhat.com/') from dual;   -- Final SQL

ERROR at line 1:
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1501
ORA-12545: Connect failed because target host or object does not exist

ORA-06512: at "SYS.UTL_HTTP", line 1441
ORA-06512: at line 1

It works for me:
orclz>
orclz> SELECT utl_http.request('https://gb.redhat.com',wallet_path=>'file:c:\tmp\wallet') from dual;

UTL_HTTP.REQUEST('HTTPS://GB.REDHAT.COM',WALLET_PATH=>'FILE:C:\TMP\WALLET')

Which certificate did you load into the wallet? You need only one, the root certificate for DigiCert High Assurance EV Root CA

I think it is a problem with release 12.2.0.1:

Your old release probably can't understand the cipher suite the certificate uses. You'll have to upgrade, 12.2.0.1 went out of premier support a year ago.

there is one workaround, it is working fine for me...

I have tried to call SENDGRID api, followed below steps...
1. Download certificates and loaded to oracle wallet.
2. Create ACL and then Assign to host.
3. Added Privileges to ACL.
4. Assign wallet to ACL using dbms_network_acl_admin.assign_wallet_acl.
5. EXEC UTL_HTTP.set_wallet('file:/u01/app/oracle/admin/DBName/wallet', '***WalletPwD**');
6. Now execute final SQL and https_Host (CN name) should be mandatory else error will be there.

select utl_http.request(url => 'https://api.sendgrid.com/v3/mail/send',
						wallet_path => 'file://u01/app/oracle/admin/DBName/wallet',
						wallet_password => '***WalletPwD**',
						https_host => '*.api.sendgrid.com'
						) resp 
from dual;

RESP
