Techniques

The following techniques can improve the process involving adoption:

Identify the purpose and scope of the adoption. Avoid an adoption on all objects if you require only a limited adoption. Select only system-defined objects if the purpose of the adoption is simply to change the family for the adoptee.
Keep models within the same family as much as possible to avoid adoptions.
Refrain from deleting and recreating objects (thereby losing original object IDs) which forces an adopt prior to a migrate.
Put procedures in place for tracking name changes that are not picked up by an adopt.
Avoid large adopts/unadopts during peak processing hours. Keep adoptions small (less than 10 minutes) if you must perform them during peak time.
Know what is running prior to an adopt/unadopt. Do not adopt if other large encyclopedia jobs are running.
Notify all encyclopedia users in advance if you must perform an adopt/unadopt during peak processing hours.
Whenever possible, schedule large adopts/unadopts to run during a time period for single stream batch processing.
Use trial adoption only when necessary to identify and exclude objects that should not be adopted, such as those with the same name, or to ensure that no unintended name changes occur.
