### Transaction Limit Exceeded

 Created by Russ Hartle, Modified on Tue, 1 Apr, 2025 at 1:45 PM by Russ Hartle

The Firebird limit is roughly 2 billion database transactions. Once a database reaches this amount of transactions, additional data cannot be written and the database will not synch or accept new synchronization connections. There is a simple fix to reset the database transaction count:

1. Stop the Firebird services
2. Rename the Database
3. Start the Firebird services
4. Run the following commands:

- gfix -mode read\_only -user sysdba -password j316fgsl “path\\to\\\*.fdb”
- gbak -v -f -t -user sysdba -password j316fgsl “path\\to\\\*.fdb” “path\\to\\\*.bak”
- gbak -v -f -r -user sysdba -password j316fgsl “path\\to\\\*.bak” “path\\to\\\*-new.fdb”
- gfix -mode read\_write -user sysdba -password j316fgsl “path\\to\\\*-new.fdb”

1. Stop the Firebird services
2. Rename the Database back to original name
3. Start the Firebird services
