BASE
Specifies the database to be modified.
Syntax
[NEW ]
B[ASE] DatabaseName [OLD ]
[PURGECF]
Parameters
DatabaseName is the name of the database to be modified. It
cannot be qualified with the group and account names.
NEW creates a new change file (DatabaseNameCF). If an old
change file exists, it is purged. This parameter is
the default.
OLD uses the existing change file and adds to it.
PURGECF purges the existing change file without creating a
new change file.
Description
Use this command to specify the name of the database you want to modify.
The BASE command must be entered before any other DBChange commands,
except COPY, HELP, OUTPUT, REDO, and XEQ. The BASE command has the three
following change file options:
* NEW--used to create a new change file. If an old change file
exists it is purged. In interactive mode, if NEW is specified and
a change file already exists, a confirmation message is displayed
asking if you want to purge the old change file and create a new
one. In batch mode, the old change file is purged automatically
and a new one is created.
_________________________________________________________________
NOTE Because NEW is assumed by default when no NEW, OLD, or
PURGECF parameter is specified, the old change file is
automatically purged (in batch mode) when the default is
used.
_________________________________________________________________
* OLD--used to enter additional changes to an existing change file.
In interactive mode, if no change file exists, the DBCPLUS program
asks if you want to create a new change file. In batch mode, if
no change file exists, an error occurs and all commands after that
are invalid.
* PURGECF--used to purge the existing change file without creating a
new change file. In interactive mode, you are prompted for
confirmation and asked if a new change file should be created
after the existing change file is purged.
Example
>base orders purgecf
To purge change file, confirm purge [y/N] ? y
Change file ORDERSCF has been purged.
No old change file. Create new file [y/N] ? y
Creating new change file:
Creating new change file: item information records
Creating new change file: set information records
Creating new change file: security table
Creating new change file: control record
>
In this example, the existing change file for the ORDERS database is
purged. The DBCPLUS program asks you to confirm the purge and returns a
message confirming that the change file ORDERSCF has been purged. The
DBCPLUS program then asks if you want a new change file created.
Messages are returned confirming the creation of the new change file.
