Efficient deletion of shipped terminal definitions

This section describes how CICS® deletes redundant shipped terminal definitions.

Overview of how shipped terminals are deleted
In a transaction routing environment, terminal definitions can be shipped from a terminal-owning region (TOR) to an application-owning region (AOR) when they are first needed, rather than being statically defined in the AOR.
Implementing timeout delete
To use timeout delete in a CICS Transaction Server for z/OS® system to which terminals are shipped, you specify two system initialization parameters.
Tuning the performance of timeout delete
A careful choice of DSHIPINT and DSHIPIDL settings results in a minimal number of mass deletions of shipped definitions, and a scheduling of those that do take place for times when your system is lightly loaded.
