About vertica-udx-zygote process and its port

Alvin_Peng

Hi,

 

I want to know how the port of vertica-udx-zygote process is configured, and can I stop the process if I don't need it?

 

From vsql I see there are three UDxZygoteProcess on three nodes, with different port:

 

dbadmin=> select * from UDX_FENCED_PROCESSES;
node_name | process_type | session_id | language | pid | port | status
-----------------+------------------+------------+----------+-------+-------+--------
v_data_node0001 | UDxZygoteProcess | | | 42900 | 22441 | UP
v_data_node0002 | UDxZygoteProcess | | | 4874 | 39778 | UP
v_data_node0003 | UDxZygoteProcess | | | 23117 | 23601 | UP
(3 rows)

 

From Vertica Guide,

 

"The HP Vertica zygote process starts when HP Vertica starts. Each node has a single zygote
process."

 

And from netstat command I see the port is bound to 0.0.0.0:

 

tcp        0      0 0.0.0.0:22441               0.0.0.0:*                   LISTEN      42900/vertica-udx-z 

tcp        0      0 0.0.0.0:39778               0.0.0.0:*                   LISTEN      4874/vertica-udx-zy 

tcp        0      0 0.0.0.0:23601               0.0.0.0:*                   LISTEN      23117/vertica-udx-z 

 

So,

1.Why the port of the process is different on different nodes? Can I set same port for them?

2.If I don't need to use UDX, can I stop the vertica-udx-zygote process?

 

Thanks a lot for your help!
