A session is a set
of instructions that describes how and when to move data from sources to
targets.
Use the Designer
to import source and target definitions into the repository and to build
mappings.
Use the Server
Manager to create and manage sessions and batches, and to monitor and stop
the Informatica Server.
When a session
starts, the Informatica Server retrieves mapping and session metadata from the
repository to extract data from the source, transform it, and load it into the
target.
More about a
Session
A session is a set
of instructions that tells the Informatica Server how and when to move data
from sources to targets. You create and maintain sessions in the Server
Manager.
When you create a
session, you enter general information such as the session name, session
schedule, and the Informatica Server to run the session. You can also select
options to execute pre-session shell commands, send post-session email, and FTP
source and target files. Using session properties, you can also override
parameters established in the mapping, such as source and target location,
source and target type, error tracing levels, and transformation attributes.
For details on server activity while executing a session.
You can group
sessions into a batch. The Informatica Server can run the sessions in a batch
in sequential order, or start them concurrently. Some batch settings override
session settings.
Once you create a
session, you can use either the Server Manager or the command line program pmcmd
to start or stop the session. You can also use the Server Manager to monitor,
edit, schedule, abort, copy, and delete the session.
