DIFFERENCE BETWEEN INFORMATICA 7.1 AND 8.1
===========================================
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.
We can use partition threads to specific custom t
