Thomas Grimm | Hello,

Fernando Dias Team Elevate | Thomas,
What version of DBISAM are you using? Whrn you say DSU repair fails, what do you mean? Are you getting an error message ? Also, if blob files are supposed to have data, please check if you have .bbk files with the same name with more than 0 bytes, and if you do, make a backup of those files right now, before any other operation on those files.

You need a .blb that at least has a valid header size (contents don't matter). As Fernando indicated, you can restore a .bbk backup of the .blb file, if you have one in in the same database directory for the table being repaired. -- Tim Young Elevate Software www.elevatesoft.com |

It was 9217 and 9218. the customer had no .bbk and no backup. (Every mail my customers get, have a footer with "Please dont forget to make backups"). My workaround was to change the 0 byte blbs against blbs of 2 empty tables where the blbs were not corrupted. After copying i did a repair run. Now the customer can run the application again and no data in the dat files seem to be lost. Was this a good idea? I am using dbisam and edb since years now, but it was the first or second case a customer had such a corrupt file that could not have been repaired. Congratulations Elevatesoft, great work. There are two components i am fully satisfied with since years: DBISAM/EDB and F......ort. |
