Configuring secure connections for grid queries

If the sqlhosts files on the grid servers include the s=6 option, you must define alternate connections for grid queries. On the grid server from which you want to run grid queries, create a grid.servers file that lists the server group names and aliases for the other grid servers.

About this task

You do not need to encrypt the file. Authentication is done through normal authentication methods.

Procedure

To configure secure connections for grid queries:

On the grid server from which you want to run grid queries, create a text file named grid.servers in the INFORMIXDIR/etc directory. List each grid server group name and alias on a separate line.

Example

For example, the following sqlhosts file for a grid uses the s=6 option for secure connections:

#dbservers    nettype   hostname   servicename   options 

g_ca_sf       group     -          -             i=100
san_francisco ontlitcp  computer1  sf_alt        g=g_ca_sf,s=6

g_ca_sj       group     -          -             i=200
san_jose      ontlitcp  computer2  sj_alt        g=g_ca_sj,s=6

g_ca_okl      group     -          -             i=300
oakland       ontlitcp  computer3  okl_alt       g=g_ca_okl,s=6

g_ca_yk       group     -          -             i=400
yreka         ontlitcp  computer4  yk_alt        g=g_ca_yk,s=6

g_ca_sac      group     -          -             i=500
sacramento    ontlitcp  computer5  sac_alt       g=g_ca_sac,s=6

g_ca_stk      group     -          -             i=600
stockton      ontlitcp  computer6  stk_alt       g=g_ca_stk,s=6

The corresponding grid.servers file has the following contents:

#group     alias
g_ca_sf    sf_alt
g_ca_sj    sj_alt
g_ca_okl   okl_alt
g_ca_yk    yk_alt
g_ca_sac   sac_alt
g_ca_stk   stk_alt
