Informix Error -41006

-41006 Protocolname is not in the [INET_PROTOCOL] section of the INFORMIX.INI

file.

Check the INFORMIX.INI file. The protocol name that is specified in the [INET_CONNECTION] section should match the protocol name that is specified in the [INET_PROTOCOL] section. The protocol name must define the correct .DLL module for that protocol. If you are using an IPX/SPX protocol, then ipx=INETIPX.DLL. If you are using a Windows Sockets 1.1-compliant TCP/IP protocol, then tcpip=INETWSOK.DLL.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-41006 fires when the protocol name given in [INET_CONNECTION] has no matching entry in [INET_PROTOCOL] — per the official guidance, the entry must map the protocol name to the correct .DLL module (e.g. ipx=INETIPX.DLL for IPX/SPX, tcpip=INETWSOK.DLL for a Windows Sockets 1.1-compliant TCP/IP protocol).

  1. The [INET_CONNECTION] protocol name having no corresponding entry in [INET_PROTOCOL], per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Add a matching entry to [INET_PROTOCOL] mapping the protocol name to its correct .DLL module, per the official guidance.
Examples
A matching protocol/DLL mapping
[INET_CONNECTION]
protocol=tcpip

[INET_PROTOCOL]
tcpip=INETWSOK.DLL
Diagnostic Checks
  1. Compare the protocol name in [INET_CONNECTION] against [INET_PROTOCOL]'s entries, and add the missing mapping to the correct .DLL module.
Related Errors / Related Topics
  • -41004 — "The INFORMIX.INI file does not have a protocolname or has a format error." A related protocol-configuration error, on the [INET_CONNECTION] protocol name itself being missing or malformed rather than unmatched.
  • -41005 — "Error in reading the [INET_PROTOCOL] section of the INFORMIX.INI file." A related [INET_PROTOCOL] configuration error, on the section heading itself.

The protocol named in [INET_CONNECTION] has no matching [INET_PROTOCOL] entry — add the mapping to the correct .DLL module.
