We all know that E-Business Suite environments requires downtime for patching. Although based on our experience it can be reduced with various techniques (e.g. staged APPL_TOP), some downtime is still required to apply a number of patches. Online patching will not eliminate downtime completely, but will reduce it significantly by using \u201cEdition Based Redefinition\u201d feature of 11g.<\/p>\n<p>So what we will be getting just to summarize:<\/p>\n<ul>\n<li>Business Operations Downtime will be measured in minutes not hours or days<\/li>\n<li>Business Operations Downtime windows will be very predictable<\/li>\n<li>Patches will be applied while the Oracle Production Application remains online<\/li>\n<\/ul>\n<p>11gR2 Edition-Based Redefinition will enable us following:<\/p>\n<ul>\n<li>Allows an application to efficiently store multiple editions of its Application Definition in the same database<\/li>\n<li>Provides an isolation mechanism (The Edition) that allows pre-upgrade and post-upgrade schemas to co-exist<\/li>\n<li>Client code chooses the particular \u201cEdition\u201d that it wants to connect to<\/li>\n<\/ul>\n<p>Dual File System for R.12.2<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/oraerp.com\/blog\/wp-content\/uploads\/2012\/06\/onlinepatching.png\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-141 aligncenter\" title=\"onlinepatching\" alt=\"\" src=\"https:\/\/i0.wp.com\/oraerp.com\/blog\/wp-content\/uploads\/2012\/06\/onlinepatching.png?resize=300%2C139\" width=\"300\" height=\"139\" srcset=\"https:\/\/i0.wp.com\/oraerp.com\/blog\/wp-content\/uploads\/2012\/06\/onlinepatching.png?resize=300%2C139 300w, https:\/\/i0.wp.com\/oraerp.com\/blog\/wp-content\/uploads\/2012\/06\/onlinepatching.png?resize=1024%2C475 1024w, https:\/\/i0.wp.com\/oraerp.com\/blog\/wp-content\/uploads\/2012\/06\/onlinepatching.png?w=1404 1404w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>End Notes:<\/p>\n<p>http:\/\/blogs.oracle.com\/stevenChan\/entry\/glimpses_of_e_business_suite<\/p>\n<div id=\"fb-root\"><\/div><script src=\"http:\/\/connect.facebook.net\/en_US\/all.js#xfbml=1\"><\/script><fb:like href=\"http:\/\/oraerp.com\/blog\/a-journey-from-oracle-e-business-suite-r12-1-to-r12-2-online-patching\/\" send=\"true\" layout=\"standard\" width=\"450\" show_faces=\"true\" font=\"arial\" action=\"like\" colorscheme=\"light\"><\/fb:like>","protected":false},"excerpt":{"rendered":"<p>Online Patching One of the hot topic during Collaborate 12 at Las Vegas along with Fusion was what is going to come in R12.2 and this post is subsequent to my earlier post\u2026where we have reviewed what new release will bring to us, lots of new features, usability improvements and new technology stack components (Oracle [&#8230;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[1],"tags":[],"class_list":["post-140","post","type-post","status-publish","format-standard","hentry","category-oracle-application-object-library"],"aioseo_notices":[],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/p1Rb79-2g","jetpack_sharing_enabled":true,"jetpack_likes_enabled":true,"_links":{"self":[{"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/posts\/140","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/comments?post=140"}],"version-history":[{"count":11,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/posts\/140\/revisions"}],"predecessor-version":[{"id":399,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/posts\/140\/revisions\/399"}],"wp:attachment":[{"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/media?parent=140"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/categories?post=140"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/oraerp.com\/blog\/wp-json\/wp\/v2\/tags?post=140"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
