DEC DATATRIEVE is a data management tool for defining, storing, updating, and displaying data. It provides interactive and program-callable access to data, a report writing facility, a graphics capability, screen formatting support, and distributed access on a network connected by DECnet. To invoke the default DEC DATATRIEVE image enter: $ DATATRIEVE Enter: $ DATATRIEVE/VARIANT=xx to invoke other DEC DATATRIEVE images that are installed on your system, where xx is the suffix appended to the image name. See the "DCL-command" help subtopic for additional information on the DATATRIEVE DCL command.
1 – Release Notes
Release notes for DEC DATATRIEVE are contained in the file: $ SYS$HELP:DTR*.RELEASE_NOTES You can type or print this file to read the release note information.
2 – UETP
DEC DATATRIEVE User Environment Test Packages (UETPs) have
been provided and can be run after the installation is
complete. They are invoked from DEC DATATRIEVE as follows:
DTR> @sys$common:[systest.dtr]dtr ! General test
DTR> @sys$common:[systest.dtr]plots ! Plots test
DTR> @sys$common:[systest.dtr]dbms ! DBMS test
DTR> @sys$common:[systest.dtr]rdb ! Rdb test
DTR> @sys$common:[systest.dtr]forms ! Forms test
3 – DCL command
You can invoke DEC DATATRIEVE from DCL command level with the
DATATRIEVE DCL command. The DCL DATATRIEVE command lets
you specify options to customize your DEC DATATRIEVE session.
You can abbreviate the DCL DATATRIEVE command to the
shortest form that is unique among other DCL commands.
The DATATRIEVE command has the following format:
DATATRIEVE [qualifier [...]] ["dtr-command-string"]
3.1 – Qualifiers
The optional qualifiers to the DATATRIEVE command include
the following:
/INTERFACE
/INTERFACE = {DECWINDOWS}
{CHARACTER_CELL}
Specifies the display interface to be used by DEC DATATRIEVE.
If your default environment is the command-line
interface, then CHARACTER_CELL is the default. If your
system is properly defined to invoke the DEC DATATRIEVE
interface to DECwindows Motif, the default is DECWINDOWS. This
qualifier overrides the setting specified by the
DTR$NOWINDOWS logical.
/DEBUG
/[NO]DEBUG
Specifies whether DEC DATATRIEVE should display special debug
messages. The default is NODEBUG.
/NO CDD
Specifies whether DEC DATATRIEVE should attach to Oracle CDD/Repository
or use textfile-based dictionary only. When this qualifier is missing,
the DEC DATATRIEVE behaviour depends on the equivalent string of
the logical name DTR$ENVIRONMENT: if the equivalent string contains
/NOCDD , no attachment to Oracle CDD/Repository occurs.
If DTR$ENVIRONMENT is not defined, the DEC DATATRIEVE behaviour depends
on the configuration selected at installation time.
If Oracle CDD/Repository is linked to DEC DATATRIEVE at installation time
its use can dynamically be disabled using the DATATRIEVE SET NO CDD
command, which switches to the textfile-based dictionary .
/VARIANT
/VARIANT = image-suffix
Indicates the 1- to 26- character suffix applied to a
DEC DATATRIEVE image upon installation to uniquely identify
that image. This qualifier is needed only if you invoke
a DEC DATATRIEVE image that was not selected as the default
image at installation time. The DATATRIEVE command in the
following example invokes DTR32FMS.EXE:
$ DATATRIEVE/VARIANT=FMS
If you want to run DTR32.EXE, and it is not the default
image on your system, use the /VARIANT qualifier alone, as
in the following example:
$ DATATRIEVE/VARIANT
3.2 – dtr_command_string
The DCL DATATRIEVE command can take a DATATRIEVE command
or statement as an argument. This allows you to execute a
DATATRIEVE command, statement, or procedure without
entering interactive DEC DATATRIEVE. If the
dtr-command-string contains more than one word, it must be
placed in quotation marks.
For example, to invoke the DEC DATATRIEVE procedure REPORT
which is located in CDD$TOP.JOB, you would enter
DATATRIEVE "EXECUTE CDD$TOP.JOB.REPORT"
4 – Motif Interface
DECwindows Motif provides DEC DATATRIEVE users with an easy way
to execute command procedures, to open and close log
sessions, to navigate through and set dictionaries, to
set other DEC DATATRIEVE setup parameters, and to display
information on certain DEC DATATRIEVE sources.
To invoke DEC DATATRIEVE with the DECwindows Motif interface, use
the following command:
$ DATATRIEVE/INTERFACE=DECWINDOWS
This qualifier overrides the setting specified by the
DTR$NOWINDOWS logical.
5 – Client for Windows
DEC DATATRIEVE Client for Windows is a Windows application which provides a user-friendly graphical interface, on Personal Computers running Microsoft Windows, for performing DEC DATATRIEVE operations on a connected server. DEC DATATRIEVE Client for Windows is layered on and requires the DEC DATATRIEVE Version 7.0 or later software which contains the Extended Client-Server API and takes care of the client-server connection and communications.
