POWER CENTER 9 NEW FEATURES

PowerCenter Effective in version 9.0, PowerCenter contains new features and enhancements.

Session Log

Session log file rollover: You can limit the size of session logs for real-time sessions. You can

limit the size by time or by file size. You can also limit the number of log files for a session.

Licensing

Enforcement of licensing restrictions: Power Center will enforce the licensing restrictions on

the number of CPUs and repositories.

Lookup Transformation

Cache updates: You can update the lookup cache based on the results of an expression. Whenan expression is true, you can add to or update the lookup cache. You can update the dynamiclookup cache with the results of an expression.

Database deadlock resilience: In previous releases, when the Integration Service encountereda database deadlock during a lookup, the session failed. Effective in 9.0, the session will not fail.When a deadlock occurs, the Integration Service attempts to run the last statement in a lookup.You can configure the number of retry attempts and time period between attempts.

Multiple rows return: You can configure the Lookup transformation to return all rows that matcha lookup condition. A Lookup transformation is an active transformation when it can return morethan one row for any given input row.

SQL overrides for uncached lookups: In previous versions you could create a SQL override forcached lookups only. You can create an SQL override for uncached lookup. You can includelookup ports in the SQL query.

SQL Transformation

Auto-commit for connections: You can enable auto-commit for each database connection.Each SQL statement in a query defines a transaction. A commit occurs when the SQL statementcompletes or the next statement is executed, whichever comes first.

Exactly-once processing: The Integration Service provides exactly-once delivery of real-timesource messages to the SQL transformation. If there is an interruption in processing, theIntegration Service can recover without requiring the message to be sent again. To performexactly-once processing, the Integration Service stores a set of operations for a checkpoint in thePM_REC_STATE table.

Passive transformation: You can configure the SQL transformation to run in passive modeinstead of active mode. When the SQL transformation runs in passive mode, the SQLtransformation returns one output row for each input row.

XML Transformation

XML Parser buffer validation: The XML Parser transformation can validate an XML document

against a schema. The XML Parser transformation routes invalid XML to an error port. When theXML is not valid, the XML Parser transformation routes the XML and the error messages to aseparate output group that you can connect to a target.

Connection management

Database connections are centralized in the domain. We can create and view database

connections in Informatica Administrator, Informatica Developer, or Informatica Analyst. Create,

view, edit, and grant permissions on database connections in Informatica Administrator.

Java Transformation

You can implement the reset Notification method in a Java transformation. When the Data

Integration Service machine runs in restart mode, this method resets variables that you use in the

Java code after a mapping run.

Web Service Consumer Transformation

The Web Service Consumer transformation consumes web services in a mapping. The

transformation can consume an Informatica web service or an external web service. The

transformation returns related groups of output data from hierarchical SOAP response messages.

Create a Web Service Consumer transformation from a WSDL data object.
