A reorganization is not required as often as is commonly assumed. The main reason for this is that Windows NT can theoretically manage an unlimited number of data files. The
limitations of the database still apply, however.You can start the
reorganization in the background.. SAPDBA uses the at command and creates a script reorg<SID>.bat in the appropriate SAPREORG directory. The script can be started at the required time, and contains all the commands necessary for starting the requested reorganization. SAPDBA also checks whether the scheduler service required for executing the at command is active.See
