IBM InfoSphere DataStage
IBM InfoSphere DataStage is an ETL tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere. It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition and the Enterprise Edition.
A data extraction and transformation program for Windows NT/2000 servers that is used to pull data from legacy databases, flat files and relational databases and convert them into data marts and data warehouses. Formerly a product from Ascential Software Corporation, which IBM acquired in 2005, DataStage became a core component of the IBM WebSphere Data Integration suite.
DataStage originated at VMark[1], a spin off from Prime Computers that developed two notable products: UniVerse database and the DataStage ETL tool.
The first VMark ETL prototype was built by Lee Scheffler in the first half of 1996[1].
Peter Weyman was VMark VP of Strategy and identified the ETL market as an opportunity. He appointed Lee Scheffler as the architect and conceived the product brand name "Stage" to signify modularity and component-orientation[2].
This tag was used to name DataStage and subsequently used in related products QualityStage, ProfileStage, MetaStage and AuditStage.
Lee Scheffler presented the DataStage product overview to the board of VMark in June 1996 and it was approved for development.
The product was in alpha testing in October, beta testing in November and was generally available in January 1997.
VMark acquired UniData in October 1997 and renamed itself to Ardent Software[3]. In 1999 Ardent Software was acquired by Informix[4] the database software vendor.
In April 2001 IBM acquired Informix and took just the database business leaving the data integration tools to be spun off as an independent software company called Ascential Software[5].
In November 2001, Ascential Software Corp. of Westboro, Mass. acquired privately held Torrent Systems Inc. of Cambridge, Mass. for $46 million in cash.
Ascential announced a commitment to integrate Orchestrate's parallel processing capabilities directly into the DataStageXE platform. [6].
In March 2005 IBM acquired Ascential Software[7] and made DataStage part of the WebSphere family as WebSphere DataStage.
In 2006 the product was released as part of the IBM Information Server under the Information Management family but was still known as WebSphere DataStage.
In 2008 the suite was renamed to InfoSphere Information Server and the product was renamed to InfoSphere DataStage[8].
•Enterprise Edition: a name give to the version of DataStage that had a parallel processing architecture and parallel ETL jobs.
•Server Edition: the name of the original version of DataStage representing Server Jobs. Early DataStage versions only contained Server Jobs. DataStage 5 added Sequence Jobs and DataStage 6 added Parallel Jobs via Enterprise Edition.
•MVS Edition: mainframe jobs, developed on a Windows or Unix/Linux platform and transferred to the mainframe as compiled mainframe jobs.
•DataStage for PeopleSoft: a server edition with prebuilt PeopleSoft EPM jobs under an OEM arragement with PeopleSoft and Oracle Corporation.
•DataStage TX: for processing complex transactions and messages, formerly known as Mercator.
•DataStage SOA: Real Time Integration pack can turn server or parallel jobs into SOA services.

At a company, I consult we do it as follows: one "live" server and one "shadow" server
The shadow server is a snapshot of the live server, comprises both the database and the web application (and respective config files). Every 2 weeks, the database data is taken from the live-DB,server,and the web application data (programs and configs) from the live-www server . Both are updated on the (single) shadow server, then the respective database and webserver processes are restarted. This is done automatically by a simple batch script.
