This configuration parameter specifies a fully qualified file path of the stash file to be used for SSL setup at server-side.
The SSL stash file has extension .sth by default, and stores an encrypted version of the key database password. The password held in the stash file is used to access the SSL key file during the instance startup.
By default, the value is null. During the instance start up, you must define if the DB2COMM registry variable contains SSL. Otherwise, the instance starts up without SSL protocol support.
