-b and negative port makes the instance read only to all clients. If you wan=
t to work around this you can:
1) maybe use anon lambdas with locals if you need to create temp vars. This i=
s the proper way to allow adhoc queries IMO anyway.
2) override query callbacks (ie pg,ps,ph etc) and write your own mechanism. T=
his is time consuming and complex unless you limit clients to canned queries=
/functions.
Studio for kdb uses the .z.pw callback and/or a password file. This is the s=
ame method for all clients.
thanks for the reply.sorry i’m a newbie :) …in the case of -b, I simply want to make theport readwrite again… or to how to remove the noupdate error..Thanks.Will.On Aug 27, 8:16?pm, Timothy Rieder <trie…> wrote:> -b and negative port makes the instance read only to all clients.

can’t do that, -b is a one-way ticket - that’s a security feature
