...
The URL of Enterprise Server to which the Peer Servers that have to be monitored are connected. For more information, refer Connection to Enterprise Server section.
Back Up Server URL
The alternate URL that should be tried for connecting to the Enterprise Server if the Enterprise Server cannot be connected to using the URL mentioned against property Server URL. For more information, refer Connection to Enterprise Server section.
| Note |
|---|
In case of Enterprise Servers in HA mode, this should point to Secondary Server URL if the primary is set against Server URL property and vice-versa. |
...
The user name to connect to the Enterprise Server. For more information, refer Connection to Enterprise Server section.
JMS Password
The password to connect to the Enterprise Server. For more information, refer to Connection to Enterprise Server section.
Server Call Timeout
Sets the timeout for the calls made to the Enterprise Server.By default it is set to 180 Seconds.
This value should be increased to avoid timeout with the Enterprise server while launching Components.
For more information, refer to Connection to Enterprise Server section.

Similarly, regular expressions can be used to match the peers on which the exception listener has to subscribe to.
Example
For example, consider four event processes EP1, EP2, EP3, and EP4.
Scenario 1.1
To fetch exceptions for EP2 and EP3 (ignore exceptions for EP1 and EP4), recommended TopicRegex is:
| Code Block |
|---|
(EP2[A-Za-z0-9_]*ON_EXCEPTION|EP3[A-Za-z0-9_]*ON_EXCEPTION) = true |
| Tip |
|---|
logical operation '|' is used in regex. |
Scenario 1.2
Scenario 1.1 can be performed in a different way as given below. This method is helpful when there are more number of EPs.
Ignore exceptions for EP1 and EP4 (fetch exceptions for EP2 and EP3) with TopicRegex as below:
| Code Block |
|---|
[A-Za-z0-9_]*ON_EXCEPTION=true
EP1[A-Za-z0-9_]*ON_EXCEPTION=false
EP4[A-Za-z0-9_]*ON_EXCEPTION=false |
| Info |
|---|
|
Scenario 1.2
To fetch exceptions for EP4 (ignore exceptions for EP1, EP2 and EP3), recommended TopicRegex is:
| Code Block |
|---|
EP4[A-Za-z0-9_]*ON_EXCEPTION=true |
Scenario 1.3
To fetch exceptions for EP1, EP2, EP3 ( ignore exceptions for EP4), recommended TopicRegex is
(EP1[A-Za-z0-9_]*ON_EXCEPTION|EP2[A-Za-z0-9_]*ON_EXCEPTION|EP3[A-Za-z0-9_]*ON_EXCEPTION) = true
| Tip |
|---|
logical operation '|' is used in regex. |
Scenario 2
Configure the Exception Listener as described in Configuration and Testing section; configure a CBR with any schema. Use feeder to send an improper message to the CBR and display component to check the output message send by Exception Listener (which is picked from the exception port of CBR) on its output port.
