I have a segment that is running out of pages. I'll have to move some of the areas to a new page group. What would be the easiest way to do so?
Chain sets cannot cross page group boundaries. So the first thing you would need 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. All you would have to do is define different segments for each of these groups of areas with each segment defining a different page group. You then create a DMCL using these segments and they are implemented. You will have to also change the DBNAMEs that reference this database to include all required segment names and specify that the DBNAME can use multiple page groups.
No UNLOAD/RELOAD required.
