Viewing and updating block or CI data in the Block/CI data panel
Use the Block/CI data panel to display the block or control interval (CI) and to modify the database.
Procedure
Access this panel from the Segment Prefix panel (option
C), or from the Initial selection panel by specifying a
block or CI number in the Blk #
field or the CI # field, or by
specifying an RBA that does not point to a valid segment code.
The Block/CI data
panel has an option to show the same block in character and hex format. The character format is
easier to read. The hex format is more compact, but more difficult to read.
The first few lines on this panel provide information that identifies the database and data set.
The lower part of the panel consists of the block or control interval. A ruler (Ofst 0...2...) helps
you to read the pointers and data. Offset indicates the location of the data from the beginning of
the block. The data is displayed below the ruler. You can overwrite the pointers and data. Press
Enter to accept your changes.
Use extreme caution when you change keys on this panel. No check is made to see whether a key is
being altered.
This panel contains the following fields:
Option
Enter an S to switch between the hex-only format and character and hex format.
DBD
The name of the database, or for a partitioned database, the name of the
partition.
DSG
The data set group number or, for a DEDB, the area number.
DBORG
The database organization type.
DSORG
The organization type of the data set.
Blk addr or CI addr
The block address or control interval address.
DS name
The name of the data set.
What to do next
Use PF3 to return to previous menus.
Important: Be sure to run the Pointer Checker utility after
you change data or pointers. If errors are found, restart IMS Database
Repair Facility and immediately select
option 3. Undo changes from
the Main menu.
The changes that you made are recorded in the Undo file until you
select option 2. View/Update database the
next time.
