APEXPassing Parameters (f?p syntax)

f?p=App:Page:Session:Request:Debug:ClearCache:itemNames:itemValues:PrinterFriendly

●App: application ID or alphanumeric alias

●Page: page number or alphanumeric alias

●Session: Identifies a session ID

●Request: Sets the value of REQUEST. Each application button sets the value of

REQUEST to the name of the button. This enables accept processing to reference the

name of the button when a user clicks it.

●Debug: Displays application processing details. Valid values for the DEBUG flag are YES

or NO.

●ClearCache: Clears the cache. This sets the value of items to null.

●ItemNames: Comma-delimited list of item names used to set session state with a URL.

●ItemValues: List of item values used to set session state within a URL.

●PrinterFriendly: Determines if the page is being rendered in printer friendly mode.

● APEXExport.class - Java program used to export Oracle Application Express applications

● APEXExportSplitter.class - Java program used to split Oracle Application Express export files into separate SQL scripts

Usage APEXExportused to export applications or workspaces

-db: Database connect url in JDBC format -user: Database username -password : Database password -applicationid : ID for application to be exported -workspaceid : Workspace ID for which all applications to be exported

or the workspace to be exported -instance : Export all applications -expWorkspace : Export workspace identified by -workspaceid or all

workspaces if -workspaceid not specified -skipExportDate : Exclude export date from application export files -expPubReports : Export all user saved public interactive reports -expSavedReports: Export all user saved interactive reports -expIRNotif : Export all interactive report notifications -expFeedback : Export team development feedback for all workspaces or

identified by -workspaceid to development or deployment

-expTeamdevdata : Export team development data for all workspaces or identified by -workspaceid

-deploymentSystem : Deployment system for exported feedback -expFeedbackSince : Export team development feedback since date in the

format YYYYMMDD
