1) test if your connectivity with your database is OK with a simple TELNET connection:
Code:
telnet <database_ip> <database_port>
$ telnet codsrv222 55010
Trying 172.30.252.222...
Connected to codsrv222.
Escape character is '^]'.
Here the port is open and this log will appear in your informix MESSAGES:
Code:
$ onstat -m
...
15:19:22 listener-thread: err = -27001: oserr = 0: errstr = : Read error occurred during connection attempt.
2) On the ILogin inform all fields.
and remember, the INSTANCE name is CASE SENSITIVE.
SERVER = $INFORMIXSERVER (DBSERVERNAME)
protocol: onsoctcp
servicename = port (on my telnet example = 55010)
database = sysmaster
