Issue/Introduction

Is there an equivalent to the BMC Bitmap program DBUBITMP, that can reset an HD database bitmap free space indicator.

Resolution

The following option is new for Database Organizer r12 and can be specified through the FUNCTION control statement: RESETBITMAP

You can now use Database Organizer to manipulate the bitmap to alter the amount of apparent free space in an HD database.

Using FUNCTION=RESETBITMAP, the database bitmap will be reset according to a BLOCKTHRESHOLD specification. This function lets you reset the bitmap as a standalone process.

FUNCTION=RESETBITMAP           
BLOCKTHRESHOLD=number_of_bytes  

Alternatively you can reset the database bitmap during the RELOAD process through the UCBITMAP control statement.

FUNCTION=RELOAD           
UCBITMAP=(threshold1,threshold2 ..threshold10)  

The detailed parameter information are listed in the Database Organizer Reference Guide, Specifying Control Statements chapter.
