>>SET
>>SET
Changes or removes the maintenance word; only the database creator can change or
remove the maintenance word. The >>SET command also sets the log identifier into the
root file, modifies access class passwords, sets a subsystem flag, and sets the critical item
update (CIUPDATE) option. For databases that will be migrated to MPE V, the >>SET
command specifies the number of input/output buffers to be allocated by TurboIMAGE in
the Database Buffer Area Control Block (DBB) depending on the number of users
concurrently accessing the database.
