ThiswhitepaperdescribeshowOracle9iApplicationServer(Oracle9iAS)onLinuxprovidesbusinesseswithanenterprise-readymiddle-tierplatformthatoffersthecost-benefitsofLinuxwhiledeliveringthecompleteandintegratedinfrastructurerequiredtosupportnewandinnovativewaysofconductingbusiness.
INTRODUCTIONOracle9iASistheindustry'sfastest,mostcompleteandintegratedJ2EE-certifiedapplicationserver.
Over11,000companiesrelyonOracle9iAStoruntheirbusinessapplicationsandWebsites.
Oracle9iAShasrevolutionizedthefast-growingapplicationservermarketbybeingfirsttointegrateallthetechnologyrequiredtobuildanddeploye-businessportals,transactionalapplications,andWebservicesinasingleproduct.
Oracle9iASsupportsallkeyJava,XMLandemergingWebservicesindustrystandards.
Itsopenandintegration-readyarchitectureensuresthatWebapplicationscanintegratewithyourITenvironment,includinglegacysystems,theapplicationsofyoursuppliersandpartners,andOracleandnon-Oracledatabases.
