The sqlhosts configuration file contains information about how client applications connect to the database server over the network.

IBM IDS comes standard with the template file sqlhosts.std
Copy it with the name sqlhosts (without extension):
Copy
cd /home/informix/etc
Copy
cp sqlhosts.std sqlhosts
And edit it:
Copy
vi sqlhosts
The file consists of 4 columns:
| dbservername | nettype | hostname | servicename |
|---|---|---|---|
Dash
The INFORMIXSERVER does not allow the dash (-) character.
In a basic installation the following lines:
| dbservername | nettype | hostname | servicename |
|---|---|---|---|
| <dbservername> | onipcshm | <hostname> | on_<hostname> |
| ol_<dbservername> | onsoctcp | <hostname> | sqlexec |
| ol_<dbservername>_hdr | onsoctcp | <hostname>_hdr | sqlexec |
Where both <dbservername> and <hostname> it is recommended that they be the host name.
The first line corresponds to the access to the server via shared memory from the host itself, with DB-Access for example.
The second line is for the socket connection via TCP / IP protocol from a client application, such as Axional Server.
And the third would be for connection to a secondary server in case you want HDR replication.
Service name
The port number of service sqlexec it is mapped at /etc/services file. In the latest OS Linux version is defined to 9088. You can set the number of port at the sqlhosts file instead of service name. If there is a Firewall, it must be allow TCP connections to the port 9088.
Once the sqlhosts file has been edited, change the owner and group to informix.
Copy
chown informix:informix sqlhosts
