Install the SSL certificate into the default JRE location or any other location using below command
Installing into a dfeault JRE location in EBS instance
# keytool -import -trustcacerts -keystore $AF_JRE_TOP/lib/security/cacerts -storepass changeit -alias gmail-lnx_chainnedcert -file gmail.cer
Install into a custom location
# keytool -import -trustcacerts -keystore <customLocation> -storepass changeit -alias gmail-lnx_chainnedcert -file gmail.cer <customLocation> -- directory in instance where the certificate need to be installed
After running the above command you can see the following response
Trust this certificate? [no]: yes Certificate was added to keystore
Running Mailer Command Line Diagnostics
Run Mailer command line diagnostics from conccurrent tier where Mailer is running, to check the IMAP connection using the below command
$AFJVAPRG -classpath $AF_CLASSPATH -Dprotocol=imap -Ddbcfile=$FND_SECURE/$TWO_TASK.dbc -Dserver=imap.gmail.com -Dport=993 -Dssl=Y -Dtruststore=$AF_JRE_TOP/lib/security/cacerts -Daccount=<gmail username> -Dpassword=<password> -Dconnect_timeout=120 -Ddebug=Y -Dlogfile=GmailImapTest.log -DdebugMailSession=Y oracle.apps.fnd.wf.mailer.Mailer
Run Mailer command line diagnostics from concurrent tier where Mailer is running, to check the SMTP connection using the below command
$AFJVAPRG -classpath $AF_CLASSPATH -Dprotocol=smtp -Ddbcfile=$FND_SECURE/$TWO_TASK.dbc -Dserver=smtp.gmail.com -Dport=465 -Dssl=Y -Dtruststore=$AF_JRE_TOP/lib/security/cacerts -Daccount=<gmail username> -Dpassword=<password> -Dconnect_timeout=120 -Ddebug=Y -Dlogfile=GmailSmtpTest.log -DdebugMailSession=Y oracle.apps.fnd.wf.mailer.Mailer

The standalone program can be run as below
$java GmailIMAPTest GmailUsername GMailUserPassword
Standalone program to verify the SMTP connection
Run the below standalone program from the concurrent tier node where Mailer is running to verify the connection with GMail SMTP server. It connects to the GMail SMTP server by authenticating with the given user name and password and sends a test email message to the give recipient user email address.
Sample program to test GMail SMTP connection
The standalone program can be run as below
$java GmailSMTPTest GmailUsername gMailPassword recipientEmailAddress
