I Get Errors When Performing Long Operations on a Very Large Model
On a very large model, transactions may time-out. This can result in a variety of problems, including the following error message: 7171 Transaction has timed out.
You can resolve this problem by increasing the time-out value for the database in which the Model resides.
To increase the transaction time-out value for a database:
1. If the database in which the Model resides is running, select the database, and then click the Stop button.
2. Start the Windows Registry Editor.
3. In the left pane navigation tree, expand HKEY_CURRENT_USER > Software > ARTiSAN Software Tools
4. Right-click on ARTiSAN Software Tools, point to New, then click Key.
5. Type SFC2 for the key name
6. Right-click on SFC2, point to New, and click DWORD (32–bit) Value to create a value.
7. Type TransactionTimeout for the value name, and set it to the number of required timeout in seconds.
8. Close the Registry Editor.
