Informatica 9 new features for developers

Informatica 9 has lot of new features including IDQ and Informatica Analyst etc this post we will focus on features which are specially useful for developers

Lookup Transformation : Cache updates. We can update the lookup cache based on the results of an expression. When an expression is true, we can add to or update the lookup cache. We can update the dynamic lookup cache with the results of an expression. 

Multiple rows return We can configure the Lookup transformation to return all rows that match a lookup condition. A Lookup transformation is an active transformation when it can return more than one row for any given input row. 

SQL overrides for uncached lookups: In previous versions We could create a SQL override for cached lookups only. We can create an SQL override for uncached lookup. We can include lookup ports in the SQL query. 

Database deadlock resilience In previous releases, when the Integration Service encountered a 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. We can configure the number of retry attempts and time period between attempts. 

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

Session Log files rollover We can limit the size of session logs for real-time sessions. We can limit the size by time or by file size. We can also limit the number of log files for a session. 

Passive transformation We can configure the SQL transformation to run in passive mode instead of active mode. When the SQL transformation runs in passive mode, the SQL transformation 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 the XML is not valid, the XML Parser transformation routes the XML and the error messages to a separate output group that We can connect to a target.
