Application design planning for data sharing

Particular considerations apply to applications for use in Db2 data sharing environments.

CACHE option of CREATE SEQUENCE statement
The CACHE option of the CREATE SEQUENCE statement is a performance and tuning option that directs Db2 to preallocate a specified number of sequential values in memory.
Applications using CICSPlex System Manager
CICSPlex® System Manager (CICSPlex SM) is a system-management tool that lets you manage several Customer Information Control System (CICS®) systems as if they were one.
Order-dependent transactions
In limited cases, one transaction, called an originating transaction, updates Db2 data with INSERT, UPDATE, or DELETE. Before completing phase 1 of the commit process, the originating transaction spawns a second transaction that is dependent on the updates of the first transaction. These types of transactions are referred to as order-dependent transactions.
