Overview
This
tool supports the efficient and parallel transfer of large data
sets from a ZLE Data Store to an analytical server for analysis
in SAS Enterprise Miner. The tool, provides an intuitive and
convenient web browser interface for transferring a table from
a ZLE Data Store directly into a SAS data set on an analytical
server.
Data
Transfer Tool provides following features:
- Ability
to transfer the data on various flavors of UNIX and Windows
platform
-
Ability to specify the format in which the data is transferred
a.k.a. the
ASCII file (delimited or CSV, Fixed Width Format), the SAS
dataset
-
Ability to Schedule the execution and monitor of an actual
data transfer
-
Ability to verify that sufficient disk space exists on the
destination
machine before the transfer begins
-
Ability to preview the first n (e.g. 100) rows
- Ability
to compress the data before transferring over the network
-
Ability to detect errors using check sum, to assure that the
data was
transferred successfully without errors.
System
Requirements
The
system and software requirements for each of the four components
of the Data Transfer Tool are described below.
Client Workstation
- Internet
Explorer 5.5 (or higher).
The
tool should work with other browsers as well, though, since
the web server component returns only HTML to a client browser
for display. In other words, no browser support for JavaScript
or anything other than HTML is required.
Web Server
- Operating
System: Windows NT/2000, HP Tru64 Unix
- Web
Server: Apache Tomcat, Version 4.0 or higher on Windows
platforms and 1.1 or higher on Tru64 platforms
- Java
Runtime Environment: Version 1.4.0 or higher
This
layer could run on the Mining Mart server itself. This is not
a necessity. The Web Server accesses the ZDS using JDBC. If
the Web server resides on Windows NT/2000, it accesses ZDS using
JDBC ODBC (Type 1) driver, if the Web Server resides on Alpha-Tru64,
it accesses the ZDS using JDBC Type 3 driver.
Mining
Mart
- Operating
System: Windows NT/2000, HP Tru64 Unix.
HP
NonStop™ Server
- NonStop™
SQL/MX version 1.5 or higher
JDBC/MX
server (needed only when a Tru64 web server platform is used)
NonStop™ Himalaya system, on which a NonStop™ SQL/MX ZLE ZDS resides.
The servers on the Himalaya system communicate with the Servers
residing on the Mining Mart (handling Transfer functionality)
using TCP/IP.
