The REORGANIZE-POINTERS statement can be used to update all the probable position pointers (PPP) contained in a user realm.
REORGANIZE-POINTERS |
REALM-NAME = <realname> |
REALM-NAME = <realname>
Name of the realm whose probable position pointers (PPP) are to be updated. The statement can be specified several times, one after the other, for different realms in the same BREORG run.
REORGANIZE-POINTERS is significantly faster than reorganizing the probable position pointers (PPP) using the other REORGANIZE functions. If all the realms in the database are handled in this way, there is no need to format the new pages when subsequently extending the realms with MODIFY-REALM-SIZE or online via the DBH. This considerably improves performance. There is no performance gain when reducing the size of a realm.
With the REORGANIZE-POINTERS statement, BREORG uses work files for the record types and an additional work file for sorting (see “Work files for the REORGANIZE- POINTERS statement”).
