asked on Changing IBMi host name search priority - best practice
Hi. We haven't changed our network structure on the IBM I for years and only recently have a need to as all of our processes have been pretty much contained on the I. I'm self taught in IBM maintenance and learning as I go but I think the changes I need to make are pretty benign but I need some advice.
I noticed my host table is totally out of whack with my network so I need to remove and correct some entries. I'm really thinking about only leaving those entries referencing my Virtual IP on the I and otherwise not using a host table. Ultimately, I need to add some DNS entries and allow external resolution. Currently my Host name search priority field under CHGTCPDMN is set to *LOCAL. Is it necessary to change to *REMOTE to make DNS active? Would this change require an IPL? If I leave that setting at *LOCAL, Do I need to make a specific entry in my host table or will lookups query my host table and then automatically jump over to DNS for those queries without a corresponding entry, provided I have the DNS server addresses listed?
I guess my question(s) are, What is best practice in this case? Do Host table changes or DNS changes require any service restarts or an IPL or can I just make these changes on the fly?

Hi Gary, Thanks for the great info. I did read through the documentation through that link and it helped narrow the focus of what I really need to do but I think I just needed real speak vs. IBM speak.. So thanks for that. In the Windows networking world, I make these changes without over-thinking it but, even though IBM is just another server OS, it has a lot of special needs and I find myself doubting or over-thinking my actions. Anyway, thanks as usual.. Your insight is always welcome.
