Issue/Introduction

If the Dataspace is getting short because of checking too many data sets in a single DBA execution and if using option MULTISPACE=Y did
not solve the storage problem, how can we check the pointer of all related primary data bases (from different data set groups and/or logical related data bases),
without also checking the content of related index data bases (primary and secondary indexes)?

Resolution

To check the pointer of several related primary data bases without also checking the index data bases, these DBA options can be used :

FUNCTION=ANALYZE,POINTERCHECK=CROSSDBD,DBDNAME=dbdname1   
FUNCTION=ANALYZE,POINTERCHECK=CROSSDBD,DBDNAME=dbdname2 
etc. (one FUNCTION statement for each primary DBD)

Using POINTERCHECK=CROSSDBD will check all pointer within this data set as well as those pointer pointing into another primary data base data set (belonging to a different Dataset Group as well as to another logical related data base).

If the index data bases also need to be checked, these additional FUNCTION statements can be used :

FUNCTION=ANALYZE,POINTERCHECK=CROSSDBD,DBDNAME=indexdbdname1   
FUNCTION=ANALYZE,POINTERCHECK=CROSSDBD,DBDNAME=indexdbdname2 
etc.
