It contrasts the one-to-one relationship of a single instance (instance and memory/processes on one server with database files) against the one-to-many model of RAC, where multiple instances access one database. RAC overview covers cluster infrastructure such as Grid Infrastructure, shared and local storage, and the need for public and private network interfaces, including NIC and switch redundancy.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/oracle-real-application-clusters-19c-technical-architecture/656392/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/oracle-real-application-clusters-19c-technical-architecture/656392.png","ImageObject",300,407,{"name":92,"@type":93},"SundayMiles","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-25",true,{"@type":102,"interactionType":103,"userInteractionCount":81},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the two basic ways Oracle Database can be configured?","Question",{"text":112,"@type":113},"Oracle Database can be configured as a single instance (SI) database or as a Real Application Clusters (RAC) database.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How do SI databases differ from RAC databases in instance-to-database relationships?",{"text":117,"@type":113},"A single instance database has a one-to-one relationship between the instance (memory and processes) and the database (database files), while Oracle RAC has a one-to-many relationship between the database and instances.",{"name":119,"@type":110,"acceptedAnswer":120},"What common infrastructure components are included in Oracle RAC clusters?",{"text":121,"@type":113},"Each RAC cluster has Grid Infrastructure (GI) installed locally on each node, and RAC uses Oracle Clusterware to bind multiple servers to operate as a single system.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},656392,1793029894,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":81,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":139,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":144,"read_time":145},1099529839202,"https://ap-avatar.wpscdn.com/davatar_a8503ba1806abce46bf441b54a3ca4cd","Oracle Real Application Clusters 19c Technical Architecture  \nCopyright © 2020, Oracle and/or its affiliates.
