2. Real Time ETL with DataMigator Agenda
Web Services
Change Data Capture
File Listener
IWAF Adapters

3. What are Web Services for?

4. 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

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

6. WSDLL.COM Web Services – Free and Commercial

7. Xmethods.net List of public web services

8. Seekda.com Find WSDL for PhoneVerify Service from cdyne.com

9. Add adapter for Web Services

10. Add Connection for a Web Service

11. Add Connection for Web Service

12. Create Synonym

13. Open Synonym

14. Sample Data Supply values for PHONENUMBER and LICENSEKEY

15. Sample Data Show all fields returned by Web Service

16. Create Data Flow Add input file

17. User Defined Function Cleans up phone number

18. Add transformation Clean up phone number and assign name

19. Add synonym for Web Service

20. Join input file to Web Service On PHONENUMBER and LICENSEKEY

21. Select Columns from Web Service

22. Test SQL Shows “join” from input file to Web Service

23. Change Data Capture
When would you want to capture changes?

24. 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…

25. 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

26. 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

27. 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

28. Create Synonym For Table Log Records

29. Create Synonym for Table Log Records

30. Synonym created for Log Table Three CDC columns added

31. 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

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

33. 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

34. UDB Synonym for Log Table

35. Data Flow Log table as source

36. Column Selection

37. Target Transformations

38. Enabled for IUD Processing IUD control column identified

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

40. CDC Flow Log shows rows inserted / updated / deleted

41. Change Data Capture Source and Target now have same rows

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

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

44. 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 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 or run flow or procedure on completion
Can schedule flows as needed

45. File Listener Create Sample Data

46. File Listener Parameters Synonym - dmordfl

47. 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

48. 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)

49. 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

50. File Name Field with Alias of INSTANCE

51. SQL or Direct Load Flow … looks like any other flow

52. File Listener Create directories listen and archive

53. File Listener Submit the Flow – Waits for TIMEOUT interval

54. File Listener Drop the Files

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

56. File Listener Sample Data

57. Log shows number of rows processed For all files

58. IWAF - iWay Adapter Framework

59. 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
