Issue/Introduction

A segment is running out of pages.

How to move some areas to a new page group.

Environment

Release: All supported releases.

Resolution

Chain sets cannot cross page group boundaries. So the first thing to do is see if there are any stand-alone areas or a group of areas that are separate from the other areas. In other words areas not connected by sets. Define different segments for each of these groups of areas with each segment defining a different page group. Then create a DMCL using these segments and they are implemented. The DBNAMEs that reference this database will need to be changed to include all required segment names and specify that the DBNAME can use multiple page groups. 

No UNLOAD/RELOAD required. The page group is not stored on the database anywhere.
