What are the differences of running FUNCTION=ANALYZE,POINTERCHECK=LOCAL/CROSSDSG/CROSSDBDor FUNCTION=ANALYZEALL using Database Analyzer?
There are different kinds of checking possible with Database Analyzer.
Just checks the pointer within a specific dataset, pointer pointing to related datasets (e.g. index databases or different dataset groups) will NOT be checked.This usually is fine if Database Analyzer will be invoked by DBCOPY to check the pointer at the same time when a dataset will be image copied.
This forces Database Analyzer also to check pointers which point into a different dataset, containing segments belonging to a differentdataset group.
This forces Database Analyzer to check all pointers for a specific dataset, including those pointing to index databases, different datasetincluding those pointing to index databases, different dataset groups or logical related databases.
This function is checking all related database datasets on the deepest level by default (POINTERCHECK=CROSSDBD) and is the recommended FUNCTION when Database Analyzer will be run as standalone execution.
