Informix Error -25558: The NFS/RFS host host-name is not listed as a dbserver name in sqlhosts.

Cause and resolution

The NFS/RFS host host-name is not listed as a dbserver name in sqlhosts.

The database server that is mentioned in the current command resides on an NFS- or RFS-mounted file system. However, no entry exists with the NFS or RFS host for the dbservername that is listed in the sqlhosts file. Ask your Informix database administrator to add the entry to the sqlhosts file. If you are using IBM Informix SE, be sure that an sqlexecd daemon is running on the NFS or RFS host.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-25558 fires when the target database server resides on an NFS-/RFS-mounted file system but no sqlhosts entry exists for that NFS/RFS host as a dbserver name — per the official guidance.

  1. No sqlhosts entry for the NFS/RFS host as a dbserver name, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Ask the database administrator to add the NFS/RFS host entry to sqlhosts, per the official guidance.
  2. On IBM Informix SE, confirm an sqlexecd daemon is running on the NFS/RFS host, per the official guidance.
Examples
N/A

No specific triggering statement is documented beyond a missing NFS/RFS sqlhosts entry.

Diagnostic Checks
  1. Check sqlhosts for the NFS/RFS host's dbserver entry, and on Informix SE, confirm sqlexecd is running there.
