Using These Settings to Administer Your Model

Because component change processing requires expansion of usages, it can be costly in processing time. This is especially true when designers (*DSNR) use it interactively. An administrator can use the YCMPCHG model value and the model profile as follows to prevent certain developers from running component change processing interactively, and as a result, minimize interactive overhead:

• Set the YCMPCHG model value to *LIMITED.
• For *DSNRs, set the model profile option to N; for *PGMRs, set it to Y.

Note: If you do not run component change processing interactively, be sure to run the Apply Component Changes (YAPYCMPCHG) command regularly; for example, overnight in batch. This keeps the model changes to be processed down to a manageable level.

When a model object is changed and component change processing is not performed immediately, CA 2E sets the Impact processed indicator to N to indicate this. You can check this indicator to decide when to run the YAPYCMPCHG command by filtering the All Objects list (*ALLOBJ) to determine which and how many objects require processing.
