Setting up automatic view maintenance

If you have multiple GUI servers, you must configure them so that only one server performs automatic network view and path view maintenance. If you have only one GUI server, you do not need to perform this task.

About this task

Network Manager performs automatic network view and path view maintenance.

Note: Only one server must perform network view maintenance. If no servers, or multiple servers, are configured to perform automatic view maintenance, undesired results can occur, such as views not being created and deleted properly.

To set up automatic view maintenance, complete the following steps.

Procedure

Choose one GUI server to perform view maintenance.
On the maintenance server, back up and edit the following file: $NMGUI_HOME/profile/etc/tnm/topoviz.properties.
To set all view maintenance properties at once, locate and uncomment the following line:
```
topoviz.engine.views.enabled=true
```
Set this property to true to enable all automatic view maintenance settings. Setting it to false disables all the automatic view maintenance settings.

Setting this property to true is equivalent to setting all of the individual view maintenance properties to true, as in the following example:
```
topoviz.engine.viewsummary.enabled=true
topoviz.engine.dynamicview.enabled=true
topoviz.engine.pathview.enabled=true
topoviz.networkview.deletedView.cleanUp.enabled=true
```
Setting the topoviz.engine.views.enabled property to false is equivalent to setting all of the individual view maintenance settings to false.

Setting this property to either true or false overrides any individual view maintenance property.

Note: All of the individual properties must be uncommented in order for the topoviz.engine.views.enabled property to take effect.
To set view maintenance properties individually, make the following changes.
1. Locate and comment out the following line:
```
# topoviz.engine.views.enabled=true
```
2. Ensure that all of the following properties are uncommented and set to true to enable them on this server:
  
  topoviz.engine.viewsummary.enabled
  
  This setting updates view membership.
  
  topoviz.engine.dynamicview.enabled
  
  This setting creates and deletes dynamic views.
  
  topoviz.engine.pathview.enabled
  
  This setting creates and deletes network path views.
  
  topoviz.networkview.deletedView.cleanUp.enabled
  
  This setting deletes views from the database when they are deleted by a user.
On each of the other GUI servers, ensure that the following line in the $NMGUI_HOME/profile/etc/tnm/topoviz.properties file is uncommented and set to false:
```
topoviz.engine.views.enabled=false
```
Save and close the topoviz.properties files.
