    Thanks for your reply. I am good now.  currently my .u.upd does not take table as input.  it works after I converted table into list:  flip = kx.q(‘flip’); ticker(‘.u.upd’,’ustrisk’, flip (df.values.tolist()))

    is there any good way to upsert list/dataframe to HDB table?

    we are using pykx to load data from kdb database and want to send data back to kdb after doing some operation:

    1. in qConnection, sendSync can read/write data from/to kdb

    2. what about pykx?

    thanks for your reply:

    1. they are internal hosts and do not have firewall/networking issue. my local PC can ping the IP

    2.  cannot open 10.106.4.131:6144  in the browser

    3.  From an existing qconnection to hopen this one, I have error like ‘hop. OS reports: No route to host’

    4. if using kx.c kdbclient3 = new kx.c(“nyblrhirsd01”, 6154, Environment.UserName + “:mypassword”),

    System.Net.Sockets.SocketException: ‘A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.106.4.131:6154’

     

    Any suggest?

    thanks for reply.

    1. from server side, I can see 6154 is running, which is open

    2. my #c code and the other good KDB server cannot make connection to the new server. my local PC can ping the new server

    Thanks for your reply:

    1. I did have new table added at the same time. it seems the new table can be back-filled;

    2. addcol works for that, but each time only add one column. do you know how to add multiple columns one time?

    August 11, 2023 at 12:00 am in reply to: how does a client server make connection to TLS enabled KDB server?

    Thanks for reply.  We did follow that doc to set up this, but failed to setup client mode:

    – connection is good between two TLS-enabled KDB servers;

    -but from a client server like an algo/pricing server, we cannot make connection to the TLS-enabled server using the following.  Can anybody suggest a correct way for that?

    new kx.c("tcps://hostserver, port, Environment.UserName + ":mypassword");
    q)h:hopen`:tcps://hostname:port[:username:password]
