Defining and changing applications

You can dynamically define JES2 as an application to VTAM® and change the characteristics of JES2 applications in the following ways:

Defining a new JES2 application: Use the $ADD APPL to dynamically define JES2 as an application to VTAM at a specified JES2 node. You identify the application name by which JES2 is known to VTAM at the indicated node (NODE=nnnn). The NODE=nnnn initialization statement that defines the node indicated on the $ADD APPL command must specify the SNA parameter. You can also specify a compaction table number and a resistance rating of the connection.
Note: When you dynamically define JES2 as an application to VTAM, its specifications are not checkpointed and are not carried across a restart of JES2. If you want to permanently define the new application, you must add a new APPL initialization statement before restarting JES2.
Changing an application's characteristics: Use the $T APPL command to specify the characteristics of one or more JES2 applications. You specify the application name, compaction table number, the node at which JES2 is defined as an application to VTAM, and the resistance rating of the connection. (For information about selecting resistance values, see z/OS JES2 Initialization and Tuning Reference, SA32-0992.)
Note: If the application is active, you cannot change the specifications.
