Hi All,

It just passed two years since Informatica Announced General Availability of PowerCenter in 8 May 5, 2006, but I can not find one comprehensive document that states the New Features and enhancements of Powercenter V8 over V7 just as in the documents in the Preface section of each guide documents in V7 in terms of details of main components in Integration service, repository service, transformations, data profiling, client tools, version control etc. I am planning to joining a private training class but hope some veterans can share me the full details of the V8 enhancements before that.

Thanks in advance,
Accel

The following summarizes changes to PowerCenter domains that might affect
upgrades to PowerCenter 8

*Object Permissions*

Effective in version 8.1.1, you can assign object permissions to users when you add a user account, set user permissions, or edit an object.

*Gateway and Logging Configuration*

Effective in version 8.1, you configure the gateway node and location for log event files on the Properties tab for the domain. Log events describe operations and error messages for core and application services, workflows and sessions.

Log Manager runs on the master gateway node in a domain.

We can configure the maximum size of logs for automatic purge in megabytes.

Powercenter 8.1 also provides enhancements to the Log Viewer and log event formatting.

*Unicode compliance*

Effective in version 8.1, all fields in the Administration Console accept Unicode characters. One can choose UTF-8 character set as the repository code page to store multiple languages.

*Memory and CPU Resource Usage*

You may notice an increase in memory and CPU resource usage on machines running PowerCenter Services.

*Domain Configuration Database*

PowerCenter stores the domain configuration in a database.

*License Usage*

Effective in version 8.0, the Service Manager registers license information.

*High Availability*

High availability is the PowerCenter option that eliminates a single point of failure in the PowerCenter environment and provides minimal service interruption in the event of failure. High availability provides the
following functionality:

Resilience.

Resilience is the ability for services to tolerate transient failures, such as loss of connectivity to the database or network failures.

Failover.

Failover is the migration of a service process or task to another node when the node running the service process becomes unavailable.

Recovery.

Recovery is the automatic or manual completion of tasks after an application service is interrupted.

*Web services for Administration*

The Administration Console is a browser-based utility that enables you to view domain properties and perform basic domain administration tasks, such as adding domain users, deleting nodes, and creating services.

*Repository Security*

Effective in version 8.1, PowerCenter uses a more robust encryption algorithm.

Also provides advanced purges for purging obsolete versions of repository objects.

*Partitioning*

There is database partitioning available. Apart from this we can configure dynamic partitioning based on nodes in a grid, the number of partitions in the source table and the number of partitions option. The session creates
additional partitions and attributes at the run time.

*Recovery*

The recovery of workflow, session and task are more robust now. The state of the workflow/session is now stored in the shared file system and not in memory.

*FTP*

We have options to have partitioned FTP targets and Indirect FTP file source(with file list).

*Performance*

Pushdown optimization

Uses increased performance by pushing transformation logic to the database by analyzing the transformations and issuing SQL statements to sources and targets. Only processes any transformation logic that it cannot push to the database.

*Flat file performance*

We can create more efficient data conversion using the new version.

We can concurrently write to multiple files in a session with partitioned targets.

One can specify a command for source or target file in a session. The command can be to create a source file like 'cat a file'.

Append to flat file target option is available now.

*Pmcmd/infacmd*

New features added to pmcmd. We can use infacmd to administer Powercenter domains.

Infasetup program to setup domain and node properties.

*Mappings *

We can now build custom transformation enhancements in API using c++ and
Java code.
