To configure a user exit for a Java class

Universal Cache User Guide : IBM InfoSphere CDC for solidDB® reference : Configuring user exits : To configure a user exit for a Java class

For Java class user exits, method names are predefined. This means that you can only enable and disable user exit programs. You need to configure a user exit in Java that implements the UserExitIF interface class provided by IBM InfoSphere CDC for solidDB^®.

Procedure

1 Click Configuration > Subscriptions.

2 Select the subscription.

3 Click the Table Mappings view and select the table mapping.

4 Right-click and select Edit Mapping Details.

5 Click the User Exits tab.

6 Select Java Class from the User Exit Type list.

7 Type the name of the Java class user exit that implements the UserExitIF interface in the Class Name box.

For example, you may have imported the UserExitIF interface, and the user exit program class that implements this interface in your function has the following definition: public class UE1 implements UserExitIF

8 In the Class Name box, type:

Option	Description
UE1	If it is a stand-alone class
<Java package>.UE1	If the class is included in a Java package (for example, com.datamirror.interface.UE1)

The files you generate from compiling the user exit program must be in a library or folder that is referenced by the CLASSPATH environment variable.

9 Type the parameters that you want to make available to the user exit program in the Parameter box.

You can access the parameters in the user exit program class by invoking the getParameter() method during the initialization process. There are no conventions for specifying the parameters. The values you type in this box are free-form. The string of parameter values cannot exceed 255 characters in length.

10 Type the name of the user exit programs you want IBM InfoSphere CDC to call beside one or more of the following operations:

Option	Description
Before Insert	IBM InfoSphere CDC runs the user exit before replicating an insert operation.
After Insert	IBM InfoSphere CDC runs the user exit after replicating an insert operation.
Before Update	IBM InfoSphere CDC runs the user exit before replicating an update operation.
After Update	IBM InfoSphere CDC runs the user exit after replicating an update operation.
Before Delete	IBM InfoSphere CDC runs the user exit before replicating a delete operation.
After Delete	IBM InfoSphere CDC runs the user exit after replicating a delete operation.
Before Refresh	IBM InfoSphere CDC runs the user exit before replicating a refresh operation.
After Refresh	IBM InfoSphere CDC runs the user exit after replicating a refresh operation.
Before Truncate	IBM InfoSphere CDC runs the user exit before replicating a truncate operation.
After Truncate	IBM InfoSphere CDC runs the user exit after replicating a truncate operation.
