Informix Error -2921: The database dbname is not compatible with the current version of IBM Informix SQL.

Cause and resolution

The database dbname is not compatible with the current version of IBM Informix SQL.

A prior version of IBM Informix software created the database that is named in the DATABASE statement in this form. Before the present system can use the database, you must use the sqlconv utility to convert it.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-2921 fires when a form's DATABASE statement names a database created by a prior version of IBM Informix software — per the official guidance, the present system can't use it until it's converted.

  1. The database was created by an older IBM Informix version, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Convert the database using the sqlconv utility, per the official guidance, before the present system can use it.
Examples
Converting the database
sqlconv mydb

Exact sqlconv invocation syntax can vary by IBM Informix version — consult the local installation's own utility documentation before running it.

Diagnostic Checks
  1. Check the database's on-disk version against the currently installed IBM Informix SQL version, and run sqlconv if they don't match.
