Server crashed due to hard disk failure , now i have restored the database and application but getting following error while opening baan.

Error : 26596 ( bdb_errno 26596 ) on Select
can not continue in ottstpstdlib (mess)

what could be the reason.

please help !!!

The "real" error number can be retrieved by subtracting 1000. In your case it means (by online manual)

-25596 The INFORMIXSERVER value is not listed in the sqlhosts file or the Registry.

The default database server name that the INFORMIXSERVER environment variable specifies must be a valid database server name in the file $INFORMIXDIR/etc/sqlhosts on UNIX or the registry on Windows. Check that the specified server is listed in the sqlhosts file or the registry.

Thanks Grzegorz ...
The problem is solved after specifying the correct server name in
sqlhosts & $BSE/lib/tabledef6.1 files.
