Using the Database Utilities

>>SET

change the language ID. This command can be issued only

on a virgin root ﬁle or an empty database.

NOTE

When reloading the database, the language must match the language ID

stored in the backup media. A DBLOAD issued in a job fails if the language of

the media differs from the database language. A DBLOAD in session mode

provides a prompt to allow you to complete the DBLOAD operation when you

reply Y.

CIUPDATE sets critical item update for the database. The following

option settings are valid:

DISALLOWED prevents any process from using the critical item update

option on this database.

ALLOWED indicates that programmatic enabling of the option is

possible through a call to DBCONTROL mode 5, but

programs that do not make this call are prevented from

using critical item update on this database. Programs that

enable the option do so temporarily for the duration of the

process but can subsequently disable it through a call to

DBCONTROL mode 6.

NOTE

ALLOWED is now the default setting. It was DISALLOWED in releases prior

to C.07.00.

ON allows all processes to use the critical item update option

on this database without the need to call DBCONTROL mode

5. Any process can explicitly disable the option

temporarily for the duration of the process through a call

to DBCONTROL mode 6 but can subsequently enable it

through a call to DBCONTROL mode 5. This setting allows

the critical item update option to be disabled in selected

programs while enabling it for the majority.

Critical item update is useful for those processes that need

to update the values of detail data set search or sort items;

master data set key items cannot be updated regardless of

the CIUPDATE setting.

BTREEMODE1 sets the root ﬁle ﬂag for B-Trees to ON or OFF. If it is ON,

then a DBFIND mode 1 on ASCII types having a B-Tree

index (explicit or implicit) and having the wildcard

character in the argument will be treated as a B-Tree

search. If set to OFF, then a DBFIND mode 1 will not be

treated as a B-Tree search, even if the item has a B-Tree.

See chapter 11, " B-Tree Indices," for more detailed

information on BTREEMODE1.

WILDCARD is set with any printable ASCII character for
