This topic discusses the elements and techniques associated with Session variables in a Logi application. About Session Variables.
What are sessions in Java?
In simpler terms, a session is a state consisting of several requests and response between the client and the server. It is a known fact that HTTP and Web Servers are both stateless.

What is the RU size for LU61?from ibm.com
specifies the maximum z/OS Communications Server request unit (RU) size that these sessions are capable of receiving. The value must be between 1 and 30720 for LU61 sessions, or 256 and 30720 for APPC sessions. The default is 4096.
What happens if value2 is not specified?from ibm.com
If value2 is not specified, or is less than value1 , it defaults to the value of value1.
What does CICS mean in LU?from ibm.com
If CICS is the secondary LU session, this indicates the maximum z/OS Communications Server request unit (RU) size that these sessions are capable of sending.
What is a SEC identifier?from ibm.com
specifies a user identifier used for sign-on (SEC=YES or MIGRATE) and referred to in security error messages, security violation messages, and the audit trail. It must be a valid userid defined to the security manager, or operators will be unable to sign on. All access to protected resources depends on USERID.
What is SNA in networking?from ibm.com
SNA allows some resources (for example, switched lines) to be defined in the network as limited resources. At bind time, z/OS Communications Server indicates to CICS whether the bind is over a limited resource. When a CICS task frees a session across a limited resource, CICS unbinds the session if no other task wants to use it.

Overview
A session attribute is a piece of summary data about a web session or custom session. For example, the total number of items in a shopping cart. Agents see session attributes across the top of a session card.
How session types relate to session attributes
When you send a custom event to Genesys Predictive Engagement through the Custom events API, the custom event specifies the session type. When we receive a custom event request that includes a new session type, we create the session type automatically. You can also use the Session types API to proactively define session types.
Present a consolidated view of multiple data points
Because custom events are specific to each organization, they can provide a wide variety of data to Genesys Predictive Engagement. This data comes as event-specific attributes. Sometimes, agents and customers need to see a different level of detail.
Create a session attribute
You create session attributes in the Session Library. Click a session name and then, on the Session attributes tab, click Create session attribute .
Projection example: Multiple custom events and projections for one session
The following example illustrates how projections are used with a custom session that has multiple custom events.
How session attributes are stored
As the Canister evaluates individual hits from a session, it maintains a set of system and user-defined session attributes. While the session is active, the Canister continues to update these attributes as needed.
Session attribute reference
Tealeaf accumulates attributes of a session as pages are passed to it for evaluation. These attributes contain useful information about the session, data size, network travel time, and event statistics.
Example
The following example shows a set of session attributes that are displayed in RTV.
Definitions
The following table defines the session attributes and provides example values.
Index-based merge reference
Also known as RTV merge, this form of merging fragments attempts to find matching fragments that are based on a specified request variable that uniquely ties the session fragments together. Typically, this variable is the unique session identifier.
Auto-merge reference
When enabled, auto-merging allows Search Server to attempt to match session fragments 24 hours before or after the main fragment. Auto-merge requires no additional configuration.
What is the RU size for LU61?

What happens if value2 is not specified?
If value2 is not specified, or is less than value1 , it defaults to the value of value1.

Why use attributes in meta programming?
Attributes are used for meta-programming. meta-programming helps you achieve dynamism with your code at runtime. Say you have 10 props in your class and you want to read only some specific props for some reason, to do this you will apply some special attributes to those props and at runtime, via reflection you will ask to filter only those props with given special attributes and then perform your job on those props. This is just one example.
What are attributes used for?

Making statements based on opinion; back them up with references or personal experience.
Do attributes force functionality?
Attributes don't force any functionality (unless out of the box). For out-of the box attributes read up the documentation on msdn. For your own attributes you need to write code on what do if a class/method etc. has an attribute.
Can attributes be applied before code is compiled?
No. Attributes can only be applied before the code is compiled.
