67: The MicroKernel cannot open the SQL data dictionary

files

The MicroKernel returns this status code for the following reasons:

 An application attempted to use a data file that is bound to a the

MicroKernel database, but the MicroKernel could not open one

of the MicroKernel data dictionary files (FILE.DDF or, if the file

has RI definitions, RELATE.DDF) or the configuration file

(DBNAMES.CFG).

 You attempted to create a file with the Replace option, and a

bound MicroKernel data file with the same name and location

already exists. However, the MicroKernel could not open the

MicroKernel data dictionary file FILE.DDF, or the configuration

file (DBNAMES.CFG).

If the data file has RI definitions, the DBNAMES.CFG file must be in

the location specified in the DBNames Configuration Location

option in the server configuration settings. Also, ensure that

FILE.DDF and RELATE.DDF (if the file has RI definitions) are in the

locations specified by the Working Directory option in the server

configuration settings.

68: The MicroKernel cannot perform the RI Delete

Cascade operation

The MicroKernel cannot enforce the Delete Cascade rule on a file

under RI control because the record that the application attempted

to delete has more than 16 levels of descendants. Delete records from

the lower levels, and then try again to delete the record that the

application was attempting to delete initially. Refer to Advanced

Operations Guide for more information about RI.

69: The Delete operation specified a file that is damaged

The application encountered an error while the MicroKernel was

attempting to enforce the Delete Cascade rule in response to a Delete

operation. This status code indicates that the related file has been

damaged and must be recreated. Refer to Advanced Operations Guide

for more information about RI and the Delete Cascade rule.
