Modifying NERV Error Handling
NERV provides some error handling properties to ensure the successful delivery of events. You can modify these properties using the Command Central user interface.
To modify NERV error handling properties
1. In Command Central, navigate to Environments > Instances > ALL > <profile_name> > NERV > Configuration tab, click the COMMON-SYSPROPS-com.softwareag.eda.nerv.properties file, and then click Edit.
2. Modify the values for the following properties:
Property | Description |
Redelivery Attempts | The maximum number of attempts that NERV makes to redeliver events, in case the initial delivery attempt fails. The default value is 100. Set to -1 for infinite redelivery attempts. Note: | When you set up the guaranteed delivery level to MAXIMUM_STRONG or MAXIMUM_EVENTUAL, the value for this property is disregarded. Instead, NERV attempts to redeliver events infinitely. |
|
Redelivery Delay | The interval (in milliseconds) at which NERV makes the redelivery attempts. The default value is 3000. |
Dead Letter Channel | The location where NERV sends any undelivered events after the maximum number of redelivery attempts has been reached. The default value is @url:sag.install.area/common/nerv/dlc. Note: | When NERV runs in the Common Platform, the @url:sag.install.area token is dynamically resolved to point to your Software AG installation directory. |
