Title/Link Abstract


CDC Scripts, User Exit and API Samples Collection of samples that illustrate how to do various tasks via MC API, User Exits, and Scripts All
How to add a sample to CDC samples exchange You too can contribute and share your sample scripts, user exits etc.


IIDR-Masker Data Masking - sample code for typical column transformations, like computing hashes over confidential data, or converting binary values (like uniqueidentifier type in MSSQL) to character strings. There is also a sample code there for writing column transformations as Groovy scripts, which can be easily replaced without CDC agent restart (and sometimes even without stopping the subscriptions).
DMXtra utilities for CDC i. The SAVF contains journal management utilities only.

Distinguishing CDC transaction ordering

Derived Sequence User Exit Sample

Document describes how to distinguish transaction/operation ordering when using IIDR's CDC Live Audit or flat file target LUW

Long running transaction in Oracle database

Script to find long running transaction in Oracle database

Document describes how to find long running transaction in Oracle database and objects involved in the transaction Oracle
Derived Sequence Examples This package contains examples of how to create a derived sequence to return an incremental value that can be used for sequencing purposes. There are examples for both derived expression and row level logic. The return type can be modified to return the appropriate data type required. All
User Exit Trace This sample user exit uses the built-in tracing functions of InfoSphere CDC. You can include the UETrace class in your own user exits and call the trace() method. Tracing will be enabled via the product's global_trace_until system parameter and logged in to our trace files. LUW
Debugging a Java User Exit in Eclipse Document which shows the detailed steps to debug a CDC user exit in Eclipse using the Java debugger tool jdb, with thanks to Michael Barton for the original post. LUW
Start & Stop CDC Instance Sample

This sample script contains the commands used to start and stop the Access Server

Start & Stop Mirroring API Sample

MC API sample that illustrates how to start and stop mirroring for InfoSphere CDC

Start Subscription using CHCCLP and Windows Scheduled Tasks CHCCLP sample script and setup instructions for how to automatically start a subscription.
Start Subscription Notification User Exit Sample This sample script demonstrates how an InfoSphere CDC notification user exit can be used to automatically restart InfoSphere CDC after an error. LUW
Notification user exit using CHCCLP to restart subscription Is an enhanced CDC notification user exit that uses CHCCLP to restart subscriptions.   Thus, if the event being acted upon in the notification is produced by a Linux, Unix, or Windows target engine, this sample can be used to restart any CDC source, including z, i, or LUW. LUW
Get Replication Status API Sample MC API sample that illustrates how to write a Java program to retrieve current CDC subscription status.   All
Get Subscription Latency API Sample MC Monitoring API sample that illustrates how to get performance statistic information such as latency All
MC API Web Monitor Sample A sample web based monitor created using MC Monitoring APIs.  The sample graphs performance-related information like latency.  It also shows subscription status and lets you view event messages. All
Java User Exit Modulo Sample

Java user exit that can be used to split a large table between subscriptions via a modulo on a numeric source table column

Check Table Mapping This an example of tool that can check the subscription mappings by using the MC Java API. It checks if the names of the tables on the source match the names of the tables on the target, table by table. In each table it checks that all columns are matched by name and that all columns are assigned. All
Notification flat file sample A sample notification user exit that will output notifications to a flat file which can be consumed by monitoring tools such as Tivoli. LUW
Force Latency User Exit Sample user exit to ensure a specified minimal latency.  This is helpful when CDC needs to be resilient and switch over in an environment that uses an asynchronous HA solution. LUW
Get Parked Tables Sample

This sample uses MC APIs to retrieve the list of 'parked' tables.


Using CHCCLP to support LDAP authentication

Sample code for supporting LDAP via CHCCLP

Presentation that guides you through how to use the sample code to be able to use CDC using LDAP authentication by using CHCCLP. All
Sample SNMP Notification User Exit Sample and document that describes the implementation of AlertHandlerIF interface, to send SNMP traps on user-specified events generated by IIDR's CDC notification user exit LUW
Mon4Dashboard A CHCCLP Java embedded script sample that inserts CDC monitoring data to DB2 tables.  This data can then be used by external monitoring solutions. All
CDC Auto Table Map Java MC API utility used to map multiple tables into a subscription using a command-line interface.  Note that with newer releases of IIDR an alternative is to use the CHCCLP command-line, All
