Unless you trust the sender, Don't click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] Hi Guys, A site wants to update the list of Windows DNS servers in use by z/OS. It's a fairly standard setup with an STC of RESOLVER getting the list from a SYS1.TCPPARMS(TCPDATA) member. (Technically, it's a unique dataset with identical info on each LPAR's assigned volume, but that should only make things more flexible.) The main LPAR is scheduled for an IPL this weekend, so that should be easy. Update the member and have it read at IPL time. Another major (production?) LPAR is not scheduled to be IPL'ed this weekend, so I'm looking at options. I believe a Stop and Start of RESOLVER should do the trick. However, I've seen some talk that I really should bounce TCPIP if I bounce RESOLVER. If I need to do that, I may request a full IPL. Any experience or advice on this. When is bouncing RESOLVER okay, and when might it byte me?
