anyone has any suggestions for pushing data to tickerplant and then to rdb? I have the following error.

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?

For python interface, which one should I pick and install?

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?

[renbright]

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

I copied 10.106.4.131:6154  in a brower,  but it shows me cannot reach the page

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?

[renbright]

thanks a lot. that works

[renbright]

Yes, I added new columns yesterday and can see it RDB. Today, I can see new data in yesterday HDB. But can not get HDB back fill using Q chk.

 

any suggest?

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?

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]
