Critical Information and Troubleshooting Tips

Admin Service DownExec property enables you to overcome dispatcher node failure. If such failure is detected on a particular dispatcher node, another dispatcher node runs a script that can execute some administration logic. For example, it can be configured to match the IP address of the failed dispatcher element, so that clients work with a new dispatcher with the same IP address as the failed one, and no functions are lost.

The name of the executable file that contains the script must be set as a value of DownExec property. The script is executed as a separate process if a connection failure with a dispatcher element occurs. The ID of the failed element is then passed as a parameter of this command. This property is used when SAP J2EE Engine 6.20 Cluster contains at least two dispatchers.

Example

Set the following in the property file of the admin service:

DownExec=.\\start.bat

The necessary operations have to be described in start.bat file in the current directory of the dispatcher node. If a dispatcher fails, this .bat file starts.
