Informix Error -25555: Server server-name is not listed as a dbserver name in sqlhosts.

Cause and resolution

Server server-name is not listed as a dbserver name in sqlhosts.

The database server name that is mentioned in the current command is not listed in the sqlhosts file. Check the server name for accuracy. Check that all database servers to be accessed are included in the sqlhosts file.

If you are using IBM Informix SE, your current working directory might be an NFS-mounted directory. Change your current working directory to a local directory, or add appropriate local directories to your DBPATH.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-25555 fires when the database server named in the current command isn't listed in sqlhosts — per the official guidance.

  1. The named server missing from sqlhosts, per the official guidance — the direct, only cause.
  2. On IBM Informix SE, the current working directory being NFS-mounted, per the official guidance — a secondary contributing case.
Solutions / Resolution
  1. Check the server name's spelling, per the official guidance, and confirm every accessed server has an sqlhosts entry.
  2. On Informix SE, change to a local working directory, or add local directories to DBPATH, per the official guidance, if the current directory is NFS-mounted.
Examples
N/A

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

Diagnostic Checks
  1. Check the server name's spelling and its presence in sqlhosts, and on Informix SE, check whether the current directory is NFS-mounted.
