What are Web Services for?

What is a Web Service? A software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically Web Services Description Language WSDL). – World Wide Web Consortium

Some sources of Public Web Services Free and commercial .net Publicly Available Commercial Web Services

WSDLL.COM Web Services – Free and Commercial

Change Data Capture When would you want to capture changes?

Why Change Data Capture? Large source databases, small batch window Want to only copy the changes Want near real-time updates Need some way to detect what has changed…

Change Data Capture How to detect changes to database tables Change the application? Track timestamp of changes, flag deletes Write changes to a separate table Compare source to target? Effective for small tables Poll the database for changes periodically? Detects additions only Use database triggers? Developer adds to database…. or automatically generated Requires staging table

Change Data Capture Data Adapter to read from database logs Read the database log… Proprietary formats Every database is different New Data Adapter for database log tables No actual staging table required Synonym describes a view of database log for one table Provides automatic checkpoint processing

Change Data Capture Database configuration Platforms and databases supported ORACLE 10g and11g on UNIX and Windows UDB on UNIX and Windows DB2 on IBM zSeries and iSeries MS SQL Server 2008 DBA issues database specific commands to Configure database to use archiving or enable logging  Add logging or enable capture mode Create additional synonym for table log records

Create Synonym For Table Log Records

Create Synonym for Table Log Records

Synonym created for Log Table Three CDC columns added

Synonym for Log Table Layout same as source table… plus three columns CDC_OPER – Operation Type I = Insert U = Update D = Delete CDC_TID – Transaction ID CDC_TIMES – Timestamp

Create Synonym for Log Table CDC Configuration Polling interval Timeout Checkpoint processing

CDC Configuration POLLING – Log polling interval for LUW TIMEOUT – Timeout interval polling for LUW START – CHKPT after last checkpoint saved CHECKPT_SAVE [YES|NO] – save last checkpoint in file CHECKPT_FILE – Location and name of file MAX_LUWS – Maximum number of LUWs processed

UDB Synonym for Log Table

Data Flow Log table as source

Column Selection

Target Transformations

Enabled for IUD Processing IUD control column identified

UDB CDC Start with Source and Target the same Run program to update source

CDC Flow Log shows rows inserted / updated / deleted

Change Data Capture Source and Target now have same rows

Change Data Capture Reprocessing For testing or reprocessing… Start at specified timestamp

File Listener Process files as they arrive in a directory… posted or copied or program output

Refactoring 7.6 Listener based Required creating and managing Listener Only Direct Load flows Only fixed length files, only character data Flow never completed… could not view log could not send email or run process flow Could not schedule flows 7.7 Adapter based All specifications in synonym, simpler to set up Either SQL or Direct Load flows Any file type, any data type Flow completes when file or time limit reached… Can send email or run flow or procedure on completion Can schedule flows as needed

File Listener Create Sample Data

File Listener Parameters Synonym - dmordfl

Data Allocation Parameters Connection – Name of a connection for an FTP Server Data Origin FILE – one time read LISTENER – process files as they arrive TAIL – future development Identify File(s) Directory – Application Directory to poll for files Name – file name, wildcards allowed Extension – file type or extension

Listening Parameters and Read Limits Polling – interval in seconds Timeout – time in seconds. If no new files arrive end job Read Limits Maxfiles – Maximum number of data files Maxrecs – Maximum number of records (only for TAIL)

Pre and Post Processing Pre Processing - Pickup IMMEDIATE – As soon as files arrives TRIGGER – Wait for trigger file with EXTENSION Post Processing - Discard DELETE ARCHIVE – Copy files to DIRECTORY KEEP – Delete trigger only and keep file

File Name Field with Alias of INSTANCE

SQL or Direct Load Flow … looks like any other flow

File Listener Create directories listen and archive

File Listener Submit the Flow – Waits for TIMEOUT interval

File Listener Drop the Files

File Listener Drop the Files - within timeout interval (60 seconds)

File Listener Sample Data

Log shows number of rows processed For all files

IWAF - iWay Adapter Framework

iWay Adapter Framework Application Adapters Data Adapters for some ERP systems New support for Application Adapters including Salesforce.com MySAP Seibel Peoplesoft So that DataMigrator can use Services Events
