DATABASE FILE CORRUPTED

Hello,

I'm developing a mobile application and the database will contain a high volume of data (1 million entries). After inserting or deleting in/from  database, the application shows this error and it won't work anymore.

What is the cause ?
How can I solve it ?

Version used: 8.3.8.58

Thank you!

Sebastian,

I’m sorry there’s been a delay in our response. Can you please upload the screenshot with a better resolution? This one looks like a preview of a bigger one and the message is not readable.

Hello,

The message in the screenshot is :

1C:Enterprise

Database file corrupted
'/data/data/com.e1c.mobile/files/1C/1cem\813246/5-a87d-54e1-eb51-e3bcb7e456b8/1Cv8.1CD'

Sebastian,

please try upgrading to version 8.3.9 or later (with a configuration update). Since 8.3.9, the mobile platform includes the "verification  and repair" feature, which will started automatically before the backup creation. This might solve the problem.

If the problem persists, please send the backup to int@1c.com, we'll investigate the issue (add "for Yulia Ivanova" to the subject to help us find your message quickly).

Corrupt file header in <Data of table '_Reference691'>
Found inconsistency between data and index of table '_USERSWORKHISTORY'
Corrupt list of records that have been deleted from table '_USERSWORKHISTORY'
In the file with infinite field values, some blocks that are not related to the field values ​​or to the list of free blocks '_USERSWORKHISTORY' are missing

Please help me fix it

I understand that this is the same problem that you described in the neighboring thread?

Hello,

I'm developing a windows application and the database already contains a large amount of data.

The work was going fine until a few days ago, when there was a power outage. After that, the application stopped importing data and it said the database file was corrupted.

What is the cause ?
How can I solve it ?

Please help me fix it

Thank you!


I use chdbfl.exe to check the database file and it gives me this error

I would like to note that we managed to solve this problem and restore the data.

One surviving data backup was of great help to us. Although it was old, it contained the table that was destroyed in the database.

In this regard, I would like to remind you once again - be sure to make backups of your data!
