-25394: Catalog of table <table_name> changed while processing <import> command; reparse failed; To restart the command append <record_no> to the infile specification.

Explanation:

You executed a command (IMPORT) to import data in a table. The definition of the table was changed during the import. The database kernel returned an error when parsing the new table definition. The import is terminated.

User Response:

After you have restored the initial state of the table, re-execute the import command or modify the original import command. Append the START <recordnumber> MAXROWS clause, which is recommended by the error text, to the original import command.
