03353040 Self-signed certificate not in database.

Explanation
A self-signed certificate cannot be validated because it is not in the key database, SAF key ring
or z/OS PKCS #11 token.

User response
Add the self-signed certificate to the key database, SAF key ring or z/OS PKCS #11
token. 
This code may also occur if the intermediate certificate on the key ring was not marked Trusted.
If using RACF key rings and the DIGTCERT and DIGTRING classes are RACLIST'ed, issue the SETROPTS
RACLIST (DIGTCERT, DIGTRING) REFRESH command to refresh the profiles to ensure that the latest
changes are available.
