Support for multiple DNS, IP and EMAIL fields in RACDCERT GENCERT

Why is it useful?
This is not just useful—it is absolutely essential for DB2 data sharing environments that run secure JDBC connections with the following settings:

enableSysplexWLB=TRUE
sslConnection=TRUE
sslClientHostnameValidation=TRUE (default starting with JDBC driver version 4.34.*)

Who would benefit from it?
Organizations using DB2 data sharing groups in a high-availability Sysplex environment will benefit. This includes enterprises that require secure, load-balanced JDBC connections across multiple DB2 members while maintaining strict SSL hostname validation for compliance and security.

How should it work?
All IP addresses and DNS names for the DB2 data sharing group must be included in the subjectAlternativeName field of the SSL certificate. This ensures that hostname validation succeeds when the JDBC driver connects to the group DVIPA and then routes to individual members. Without this configuration, SSL hostname validation will fail, breaking secure connectivity.
