Initialize Electric Trace Weights prepares a new database for Feeder Manager 2.0 functions by populating the field with the model name MMELECTRICTRACEWEIGHT; this field must also be associated with the MMElectricTraceWeight weight created when the geometric network is built. Initializing also adds to this field information found in bitgates.

Before You Begin

Ensure your MaxLocksPerFile Registry settings are high values (200,000 for example). A low setting will cause errors during initialization. There are three MaxLocksPerFile entries in the Registry at the following locations:

How Geometric Networks Affect Initializing Electric Trace Weights

You can use the Initialize Electric Trace Weights function before or after creating a geometric network. However, it is recommended that you run Initialize Electric Trace Weights before creating the geometric network because the initialization process will be much faster. Running this function after creating a geometric network can be very slow.

Initializing Trace Weights in SDE Geodatabases

If you are using the initialize Electric Trace Weights function on a dataset in an SDE geodatabase, it is highly recommended that you use it before registering the dataset as versioned and before you create a geometric network. If the dataset is versioned, it may require a significant amount of time to initialize trace weights. For example, the process could take several days for a dataset with more than 100,000 edges because of the overhead involved in updating weight-associated fields in a versioned database.

You can initialize trace weights in an SDE geodatabase when:

You cannot initialize trace weights in an SDE geodatabase when:

Function Availability

Below is a table that describes when the Initialize Electric Trace Weights function is available in each type of geodatabase.

Geodatabase Type	Geometric Network	Registered as Versioned	Initializing Trace Weights Available
personal	no	n/a	yes
personal	yes	n/a	yes
file	no	n/a	no
file	yes	n/a	yes
SDE	no	no	yes
SDE	no	yes	no
SDE	yes	no	no
SDE	yes	yes	yes

 

Initialize Trace Weights With NO Geometric Network

This procedure applies to personal and SDE geodatabases and cannot be performed on file geodatabases. Initializing trace weights before creating the geometric network is much quicker than initializing with the network already created. To initialize trace weight values before the network is created:

1. Ensure a geometric network does not exist.
   If a geometric network does exist but you want to initialize the dataset without the geometric network; drop the geometric network and compress the geodatabase.

2. If initializing an SDE geodatabase, check whether the dataset is registered as versioned.
   If the dataset is registered as versioned, delete any versions and unregister the dataset as versioned. 

3. Select the electric dataset.

4. Click the Initialize Electric Trace Weights button.

5. A dialog box will display the feature classes that will be updated. Only feature classes containing a field with the MMElectricTraceWeight field model name will be affected. Click Yes to proceed or No to cancel.

6. When you run Initialize Electric Trace Weights without a geometric network, Feeder Manager creates the following .txt files. 

   • FdrMgrWeightInitSQL.txt is a log file of all SQL statements that were used to update the tables.
   • FdrMgrWeightInitLastStatement.txt stores only the last SQL statement that executed successfully. If this statement matches the last statement in the FdrMgrWeightInitSQL.txt file, then Initialize Electric Trace Weights executed successfully.

In Windows XP, Windows Server 2003 and Windows Server 2003 R2, these files are stored in the following directory: Documents and Settings\[User]\Application Data\Miner and Miner\ArcFM. In Windows 7, Windows Server 2008 and Windows Server 2008 R2, these files are stored in the following directory: Users\[User]\AppData\Roaming\Miner and Miner\ArcFM.

Initialize Trace Weights With a Geometric Network

If you do choose to initialize weight values after the geometric network has been built, it is recommended that you disable Feeder Manager's tracing autoupdaters.

To initialize trace weight values after the network is created:

1. Disable Feeder Manager's tracing autoupdaters.
   • Right-click the geometric network and select Feeder Manager | Settings.
   • Uncheck the Tracing Autoupdaters Enabled field. Do NOT disable the weight autoupdater while initializing trace weights when a geometric network exists.
   • Click Save. The change is effective immediately, without the need to restart ArcCatalog.
2. Select the electric geometric network feature class.
3. Right-click and select Feeder Manager | Initialize Electric Trace Weights.
4. Check the event log. If it shows no errors, trace weights were successfully initialized. 

Initialize a Dataset Registered as Versioned and With a Geometric Network

This procedure applies to only SDE geodatabases. Before using this procedure, be aware that initializing trace weights when the network already exists and the dataset is registered as versioned could take a significant amount of time and generate several conflicts.

1. Ensure that the dataset is registered as versioned. 
2. Select the electric geometric network feature class.
3. Right-click and select Feeder Manager > Initialize Electric Trace Weights.

   

4. Check the event log. If it shows no errors, trace weights were successfully initialized.
