joblog information,whichincludesenvironmentsettingsandotherinformationthatyoulater
use to validate the resultsonthe targetsystem.
2. Backingup the installation
Before youbeginexporting InfoSphere InformationServer fromyoursource computerandafter

3. SavingInfoSphere DataStage settingsfiles
Save the settingsfilesfromthe source installation.Thenafteryouinstallthe new version,
integrate the savedsettingsintothe settingsfilesonthe targetinstallation.
4. Movingjobdependencyfiles,hashedfiles,andjoblevelmessagehandlers

5. New Features in 11.3
Introduction
With the release of Information Server/DataStage 11.3 a few weeks ago, most DataStage developers are
interested in knowing exactly what new features have surfaced and how they can best be leveraged. With
the release of version 8.7, IBM introduced the Operations Console and version 9.1 followed in-line with
the release of the Workload Manager. I’m afraid that DataStage developers don’t have anything too
exciting to look forward to in version 11.3. There are definitely some nifty new features tacked on the suite
from the standpoint of data governance, metadata management, and administration, but this post will
review just the new features in DataStage.
There might be some hidden new features or “features” which aren’t documented. Feel free to comment
below on what you think they might be.
Hierarchical Data Stage
Remember how the XML stage was pretty recently introduced for all XML processing in DataStage? Well
now it has been relabeled as the Hierarchical Data stage, I suppose to account for its ability to process all
types of Hierarchical Data (JSON) as opposed to strictly being limited to XML. This stage also has some
additional functionality which wasn’t previously available. If you are familiar with this stage (Hierarchical
Data/XML) you will know it has various steps which are added in the Assembly Editor, for a sequence of
processing events. There are now three new steps:
 REST – Invokes a RESTful web service
 JSON_Parser – Parse JSON content with a selected type
 JSON_Composer – Compose JSON content with a selected type

6. Big Data File Stage
The Big Data File stage is used to read and write to files on Hadoop (HDFS). The Big Data File stage is
now compatible with Hortonworks 2.1, Cloudera 4.5, and InfoSphere BigInsights 3.0.
Greenplum Connector Stage
You can now use the Greenplum Connector stage for a native connection for accessing data which is
located in a Greenplum database. You can now also import Table Definitions using the Greenplum
Connector framework.
InfoSphere Master Data Management Connector Stage
The Master Data Management Connector stage can be used to read and write data from the IBM master
data management solution – InfoSphere MDM. This stage can be configured for Member read and
Member write interactions from the MDM server.
Amazon S3 Connector Stage
Amazon S3 (Simple Storage Service) is a cheap cloud file storage system which offers availability
through web services (REST, SOAP, and BitTorrent). It offers scalability, high availability, and low latency
at extremely competitive prices. The Amazon S3 Connector stage be can used to read and write data
residing in Amazon S3.

7. Unstructured Data Stage – Microsoft Excel (.xls and .xlsx)
The Unstructured Data stage was first introduced in DataStage v9.1 and was used to read Excel files
through a native interface. Previously, Excel data was staged as a .csv file or accessed through ODBC.
The stage can also now be used to write data to Excel files.
Sort Stage Optimization
The Sort stage now tries to optimize your DataStage sort operations by converting length bounded
columns to variable length before the sort and then converts it back to a length bounded column after the
sort. When a record’s actual size of data is smaller than the defined upper bound, the optimization will
result in reduced disk I/O.
Improved Flexibility in Record Delimiting
The Sequential File stage now gives developers more flexibility with how a source flat file has to be
delimited. A new environment variable, APT_IMPORT_HANDLE_SHORT, can be set to enable the
import operator the ability the read in records which do not contain all of the fields defined in the import
schema. Previously, these records were rejected by the stage. The values assigned to any missing field
depends on the data type and nullability.
Operations Console/Workload Management
IBM lists the Operations Console and Workload Management as new features of the 11.3 release
documentation, even though these components have already been introduced in previous releases. Both
components are now part of the base Information Server installation and Workload Management is now
by default enabled.
