        ADF Faces Tuning<\/h2><\/span>\n

        General<\/h3><\/span>\n

        * User partial page navigation
        \n* Use page templates
        \n– Avoid using <f:subview> whenever possible
        \n– Avoid long IDs
        \n* Minimize ADF rich client geometry management
        \n– Minimize number of child components within a parent geometry managed component such as:<\/p>\n

        \r\nPanelAccordion\r\nPanelStretchLayout\r\nPanelTabbed\r\nBreadCrumbs\r\nNavigationPane\r\nPanelSplitter\r\nToolbar\r\nToolbox\r\nTable\r\nTrain\r\n<\/pre>\n
        * Minimize component overflow by setting a big enough initial size
        \n– The components that have built-in support for overflow are: <\/p>\n
        \r\nPanelTabbed\r\nBreadCrumbs\r\nNavigationPane\r\nPanelAccordion\r\nToolbar\r\nTrain\r\n<\/pre>\n
        * Use PPR (partial page rendering) whenever possible
        \n– Use panelTabbed (supports PPR) instead of navigationPane (no PPR)
        \n* Cache resources whenever possible
        \n– Cache all static resources (e.g. setup F5 Big-IP rules)
        \n* Define custom styles at the top of the page
        \n– Use metaContainer facet<\/p>\n
        \r\n\r\n\r\n\r\n.TabletNavigationGlobal {\r\ntext-align: right;\r\npadding-left: 0px;\r\npadding-right: 10px;\r\nwhite-space: nowrap;\r\n}\r\nHTML[dir=rtl] .TabletNavigationGlobal {\r\ntext-align: left;\r\npadding-left: 10px;\r\npadding-right: 0px;\r\n}\r\n<\/style>\r\n]]>\r\n\r\n<\/af:group>\r\n<\/f:facet>\r\n\r\n\r\n<\/af:form>\r\n<\/af:document>\r\n<\/pre>\n
        * Bundle custom JavaScript code and include needed module in client side use:<\/p>\n
        \r\n\r\n<\/pre>\n
        trinidad-config.xml Configurations<\/h3><\/span>\n
        * Disable debug-ouput element (set to FALSE)
        \n* Disable animation<\/p>\n
        web.xml Configurations<\/h3><\/span>\n
        * Minimize state token cache<\/em> size:
        \norg.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS=
        \n(2 to support one back button click) or (1 to disable support for back button)
        \n* Disable test automation:
        \noracle.adf.view.rich.automation.ENABLED=FALSE (default)
        \n* Disable client side assertions in web.xml:
        \noracle.adf.view.rich.ASSERT_ENABLED=FALSE (default)
        \n* Disable JavaScript profiler:
        \noracle.adf.view.rich.profiler.ENABLED=FALSE
        \n* Disable resource debug mode (so that static resources can be cached):
        \norg.apache.myfaces.trinidad.resource.DEBUG=FALSE
        \n* Disable timestamp checking:
        \norg.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION=FALSE (default)
        \n* Disable css file checking:
        \norg.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION=FALSE
        \n* Enable content compression:
        \nDISABLE_CONTENT_COMPRESSION=FALSE
        \n* Enable JavaScript obfuscation(to reduce file size):
        \norg.apache.myfaces.trinidad.DEBUG_JAVASCRIPT=FALSE
        \n* Enable library partitioning:
        \noracle.adf.view.rich.libraryPartitioning.DISABLED=FALSE
        \n* Disable checking JSP file modifications
        \noracle.adf.view.rich.CHECK_FILE_MODIFICATION=FALSE
        \n* oracle.adf.view.rich.CLIENT_STATE_METHOD=token (default)?
        \n* oracle.adf.view.rich.LOGGER_LEVEL=OFF<\/p>\n
        \r\n\r\n  oracle.adf.view.rich.LOGGER_LEVEL<\/param-name>\r\n  OFF<\/param-value>\r\n<\/context-param>\r\n<\/pre>\n
        Component Attributes<\/h3><\/span>\n
        * Use immediate<\/em> in certain cases
        \n* Prefer rendered <\/em>attribute over visible<\/em> attribute
        \n* Use client-side events whenever possible and prevent event propagation to server side (e.g. cancelling event at the end of processing)
        \n* Use id<\/em> attribute that is less than seven characters
        \n* Use client-side components when necessary by useing clientComponent<\/em> attribute
        \n* Set the childCreation attribute on af:popup to deferred for a server-side performance enhancement.<\/p>\n
        Table and Tree Component Configurations<\/h3><\/span>\n
        * Keep table fetch size and iterator range size in sync
        \n* Disable column stretching (default)
        \n* Minimize use of header rows and frozen columns<\/p>\n
        DVT Components<\/h3><\/span>\n
        * Modify the RangeSize attribute
        \n* Minimize vertical text<\/p>\n
        Others<\/h3><\/span>\n
        * Turn on database table indexing when using autoSuggest<\/p>\n
        ADF Server Tuning<\/h2><\/span>\n
        View Objects Tuning<\/h3><\/span>\n
        * Use least resource intensive view objects (read-only, insert-only, etc)
        \n* Configure view object data fetching behavior properly:
        \n– Fetch mode
        \n– Fetch size
        \n– Max fetch size
        \n– Forward-only mode
        \n* Consider optimize large data set
        \n* Disable “spillover” configuration when possible (i.e. set jbo.use.pers.coll=false)
        \n* Review SQL style configuration (e.g. -Djbo.SQLBuilder=”SQL92″)
        \n* Use bind variables for view object queries to maximize reuse.
        \n* Use query optimizer hints
        \n* Use dynamic SQL generation
        \n* Use batch processing when possible (BatchThreshold property)
        \n* Set RangeSize equal to number of records to be displayed in UI (avoid round trips)<\/p>\n
        Application Module (AM) Tuning<\/h3><\/span>\n
        * Use large AM to minimize database connection instances.
        \n* Use lazing loading (-Djbo.load.components.lazily=true)
        \n* Use AM pooling (configure in bc4j.xcfg file)<\/p>\n
