Suite and product module changes


Bottom
System requirements
InfoSphere Information Server has added support for several new operating systems, database servers, application servers, and web browsers. For more information, refer to System Requirements.
Installing
Expanded high availability (HA) and scalability options
InfoSphere Information Server now supports a wider variety of topologies for HA and scalability:
  • The services tier can now be implemented within an IBM WebSphere® Application Server Network Deployment clustered environment.
  • The metadata repository tier can now be implemented within a DB2® database cluster or HADR configuration, or an Oracle database Real Application Clusters (RAC) configuration.
  • InfoSphere Information Server components can now be implemented on redundant servers that are managed by HA management software such as IBM Tivoli® System Automation for Multiplatforms.
For more information, refer to High availability configurations.
Redesigned installation program
The InfoSphere Information Server installation program now runs within a standard Web browser, or in silent mode from the command-line. It performs a thorough requirements check that helps ensure that the installation is successful. It supports incremental removal of products and tiers as well as incremental installation. It can optionally install WebSphere Application Server and DB2. For more information, refer to Installing new software.
Multiple analysis databases and how they relate to installing InfoSphere Information Server
IBM InfoSphere Information Analyzer now supports multiple analysis databases. Each InfoSphere Information Analyzer project is associated with a specific analysis database. The analysis database might be used by a single InfoSphere Information Analyzer project, or it might be shared by multiple InfoSphere Information Analyzer projects. For more information about what you need to know at installation time, refer to Locations for the analysis databases.
Secure HTTP (HTTPS) support
IBM InfoSphere Information Server supports HTTPS communication between the application server and client components. If your environment requires confidentiality at this level, you can enable HTTPS.
HTTPS provides two benefits:
  • Encryption: Data sent over an HTTPS connection is encrypted.
  • Identification: Communication is allowed only if the server is positively verified. Before communications begin, the server sends the client a certificate. The signature in the certificate is decrypted by the client to verify the authenticity of the sender.
HTTPS configuration is optional. If you do not configure HTTPS, HTTP is used instead.
For more information, refer to Secure Sockets Layer (SSL) configuration.
Secure Sockets Layer (SSL) for inbound RMI/IIOP is disabled by default
SSL for inbound RMI/IIOP is no longer enabled when you install InfoSphere Information Server. You must now actively enable this security feature. For more information, refer to Enablement of Secure Sockets Layer (SSL).
Administering
New Auditing Service
The Auditing Service creates an audit trail of security-related events. This includes all activities that set or modify security-related settings and all user authentications and application logins. You can configure which audit events to log and how much information to include based on auditing requirements. For information about how to configure the Auditing Service, refer to Audit logging configuration.
New roles
There are new roles for common metadata, IBM InfoSphere Business Glossary, and InfoSphere Information Analyzer. For more information, refer to Security role overview.
New entitlement scheme
IBM has changed the entitlement scheme for InfoSphere Information Server. IBM no longer supplies each customer with a custom license file that programmatically restricts the product modules and components that can be installed and used. Instead, all InfoSphere Information Server product components and features are presented for installation. It is your responsibility to install only those items that are indicated on your Proof of Entitlement.
When you install IBM InfoSphere DataStage®, the program prompts you to select the InfoSphere DataStage editions and feature packs to install and activate. Each item in the selection list enables associated InfoSphere DataStage canvases and job features. Select the items for which you have a valid Proof of Entitlement from IBM. The installation program activates the features that are associated with the items that you select. Any other editions or feature packs are deactivated and cannot be used.
If you later acquire entitlements for an additional InfoSphere DataStage edition or feature pack, to use the features that are included in the item you must activate the item by using the LicensingServiceAdmin tool. If you no longer have entitlement for an item, you must deactivate it by using the tool. When you deactivate the edition or feature pack, the features within the item are no longer available for use.
For more information, refer to Activating entitled IBM InfoSphere DataStage editions and feature packs.
New URL for the web console
The URL for the InfoSphere Information Server web console is http://hostname:9080/ibm/iis/console. The previous URL was http://hostname:9080/.
Reporting
Report templates
Provides report templates for the suite components that you installed. The Information Center provides tables that detail the roles, permissions, and result formats for all report templates. For more information, refer to Available reports and templates.
Data source connectors
Connectors for Server jobs
You can now use IBM InfoSphere Connectors to create and run InfoSphere DataStage Server jobs.
Connector migration tool support
Provides support for InfoSphere DataStage server jobs.
z/OS® File Stage
You can now use the Z/OS File Stage to read and write mainframe resident native files seamlessly from InfoSphere Information Server, running on non-Z/OS platforms. This requires IBM InfoSphere Classic Federation.
Distributed Transaction Stage
Provides the following additional targets: ODBC and IBM WebSphere MQ.
Connectors support multiple input links
You can now create multiple input links and configure the write methods in the target connector stage.
New data integration project management tool
Blueprint Director is a new capability to further strengthen the alignment of business and IT allowing you to govern your information projects. The integration team can collaborate on actionable information blueprints that connect the business vision with the corresponding technical metadata. It directs the team to apply best practices based on reference architectures and methodology.
Moving assets between installations of InfoSphere Information Server
You can now use the istool command line to move the following types of assets between metadata repositories:
  • InfoSphere Business Glossary assets: Categories and terms and links to assigned assets and to stewards.
  • InfoSphere FastTrack assets: Project templates, projects, mapping specifications, mapping components, and their related assets.
  • InfoSphere Information Analyzer assets: Projects, data classes, and the common metadata and reports that are associated with projects.
  • Reporting assets: Reports and report results that are created in the InfoSphere Information Server console or Web console.
  • Security assets: Users, groups, roles, and credentials for InfoSphere Information Server.
In previous releases only InfoSphere DataStage and QualityStage assets and common metadata could be transferred between repositories. This new functionality lets you move a wide range of inter-related InfoSphere Information Server assets between development, test, and production environments. For more information, refer to Managing assets by using the command line.
Full command-line support for MetaBroker® and bridge imports
You can import metadata by using the command-line and automatically save your import parameters and filter settings to files for future command-line use. In previous releases, command-line support was limited and required manual creation of parameter XML files. For more information, refer to Importing metadata by using the command line.

For information about how to view the details of an asset, which includes these values, refer to Viewing the properties of an asset.
Basic User role
This new user role enables InfoSphere Business Glossary business users to view only the information most relevant to them. Users who are assigned only this InfoSphere Business Glossary role can view business terms and their attributes. These users cannot view assigned assets and data sources. For more information, refer to Roles.
Business intelligence to business glossary import
You can now import a business intelligence (BI) model, such as an IBM Cognos® Framework Manager model or a BusinessObjects Universe and create a structured glossary from it. Because, in many cases, business intelligence reports represent the intersection of business language and key data, these models can be excellent sources for initial population of glossary content.
