Issue/Introduction

Description:

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

Solution:

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

You can now use CA 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 r12 Reference Guide, Specifying Control Statements chapter.
