Complete the following steps to make ODBC connections:
Before making an ODBC connection, ensure that the NUCLEUS variable is set in the SYSTEM variables as shown below:
NUCLEUS=SUPPORT:<Installation location which contains nucleus.ini file>
Create the DSN with the host name as a fully-qualified domain name. If the host name is part of the subject alternate names, you can use just the host name. For example:
If the host name is "myhost" and the domain is "mydomain.com," if "myhost" is not added in the subject alternate names, input the host name as:
myhost.mydomain.com
Otherwise, if "myhost" is added in the subject alternate names, you can input only "myhost" in the host field when you create the DSN.
Since you set the NUCLEUS variable as a pre-requisite, the nucleus.ini file in the location is updated with the new DSN name with the connection name as provided when you created the DSN.
Under the corresponding [CONNECTION] name, verify that the host name is exactly as given during DSN creation.
Add the following entries under [CONNECTION]:
CertFile = <full path and name of the CA certificate file or self-signed certificate file>
SSL=1
