To specify an event handler from EAServer Manager:
Double-click the Servers folder.
Highlight the server for which you are specifying the event handler.
Select File | Server Properties.
Select the Handlers tab.
Enter the DLL or shared library name and the function name of the specific event handler being called, separated by a colon.
The following examples illustrate an entry for a connect event handler for Solaris and Windows:
Solaris
libsamp.so:debug_connect
where libsamp.so is the shared library name and debug_connect is the function called whenever a connect event handler is called.
Windows
libsamp.dll:debug_connect
where libsamp.dll is the DLL name and debug_connect is the function called whenever a connect event handler is called.
Table B-1 summarizes the types of event handlers that you can install. For information on coding event handlers, refer to“Additional event handler information” and your Open Server documentation.
