1. Log on as the root user at the Secure Gateway server.
   
2. At the command prompt, type: ctxcertmgr -response filename [ -dbpassword db-password ] 

-response	Specifies the certificate is a response to a certificate request generated using ctxcertreq
filename	Specifies the certificate file supplied by the CA
-dbpassword	Specifies the password used to protect the certificate on the Secure Gateway server. This is the database password you supplied when you ran ctxcertreq.   If you include the -dbpassword option, you must use the db-password parameter to specify the new password, which should be a maximum of 255 characters in length.   This option is used if you are including commands in a shell script. Using -dbpassword displays the password on the terminal and enters it into the user’s command line history.
