3 Feature Analysis 3

4 How to find the new features? 4 Documentation (BETA) Actually compute the delta between different APEX versions: - APEX Dictionary - Packages

5 Wie wurde analysiert? 5

6 How to find the new features? 6 In Debug-Mode (logged in as developer) APEX uses the uncompressed Javascript Files (Source Code)

7 How to find the new features? 7

8 How to find the new features? 8 Pre 5.2 Definition in User-Interface > Concatenated Files Sample: Oracle APEX Page Designer, Application 4000, Page 4500

9 Sample Application will be made available 9

10 Architecture 10

11 Additional x11-x20 Parameters in AJAX calls 11 The big archtitecture change was in APEX 5.1 => JSON processing Small change in 5.2: Additional Parameters for AJAX calls x11-x20 Javascript on client PL/SQL on server side

12 Application Builder 12

13 Resource Links 13 New Resource Links on APEX Workspace Homepage Shortcuts on Community Site Twitter, Youtube, LinkedIn, Facebook Great idea but everybody has different needs

14 Custom Resource Links 14 Customizing the Workspace or Instance Announcement (HTML is only allowed here, not in the news items)

15 Custom Resource Links 15 Customizing the Workspace Announcement

16 Spotlight Search 16 Powerful Search Feature (like on the Mac) to search for Workspace and application areas and navigates there (Packaged Apps, SQL Workshop, Shared Components,...) Applications Pages Application content within pages, etc. Context dependent (Workspace, Application, Page Designer)

17 Spotlight Search 17

18 Spotlight Search 18 How to figure out the right keyboard shortcut in your language? CTRL- on an English layout what is the representation of in a different language? CTRL-ä on a German layout

19 Compatibility Mode 19 The compatibility mode changes the behaviour of the APEX engine at runtime => balancing new features / security / stricter checks and easy upgrades => No Changes in APEX 5.2

20 Default Schema 20 Pre 5.2 Set default schema for user in workspace

21 Default Schema 21 Pre 5.2 Default schema is used: SQL Workshop Installation of packaged applications

22 User Interface Attributes > Collapsed by Default 22 Universal Theme starts with left navigation side collapsed

23 User Interface Attributes > "Built with APEX" Footer 23 Universal Theme has a new footer Can be turned off in User Interface Attributes

24 Application Building 24

25 New Authentication Scheme 25 New Authentication Scheme Social Sign-In Authentication Provider

26 New Authentication Scheme 26 About OAuth2 and its flow /identity/protocols/oauth2

27 New Authentication Scheme 27 Example: Steps to authenticate with Google 1. Register oauth2 client with Google 2. Create web credentials in APEX 3. Create authentication scheme and use credentials

28 New Authentication Scheme Register client with Google Register client:

29 New Authentication Scheme 29

30 New Authentication Scheme Create web credentials in APEX

31 New Authentication Scheme Create authentication scheme and use credentials

32 New Authentication Scheme 32 Scopes googlescopes#google_sign-in

33 Switching Authentication Schemes at Runtime 33 Why use multiple authentication schemes at runtime?

34 Switching Authentication Schemes at Runtime 34 Step 1 make apex login current scheme Step 2 - Enable switch in session for the Google scheme

35 Switching Authentication Schemes at Runtime 35 Step 3 - Add button to login page and use a URL to switch to the Google scheme Request variable: APEX_AUTHENTICATION=<Scheme Name> f?p=&app_id.:1:&app_session.:apex_authentication=google

36 Switching Authentication Schemes at Runtime 36 Post Authentication Handler change username -- derive new username from :APP_USER case :app_user when then l_new_app_user := else -- will not change l_new_app_user := l_orig_app_user; end case; -- set user for this session apex_custom_auth.set_user( p_user => l_new_app_user );

37 Switching Authentication Schemes at Runtime 37 Post Authentication Handler get scope attributes -- get attribute by name apex_json.get_varchar2( p_path => 'id_token' ); apex_json.get_varchar2( p_path => 'access_token' ); -- or loop over all attributes l_idx := apex_json.g_values.first; while (l_idx is not null) loop l_value := apex_json.g_values(l_idx); :p2_user_info := :p2_user_info get_output_str( p_idx => l_idx, p_value => l_value ); l_idx := apex_json.g_values.next(l_idx); end loop;

38 Switching Authentication Schemes at Runtime 38 Post Authentication Handler make additional request -- second request, to retrieve additional user information c := apex_web_service.make_rest_request ( p_url p_http_method => ' => 'GET', p_credential_static_id => 'GOOGLE' ); apex_json.parse(c);

39 Application Access Control 39 Management of Roles and User / Role Mappings as part of the application Why? Convenience, almost every application needs it Used for blueprint applications

40 Application Access Control 40

41 Application Access Control 41

42 Application Access Control 42 Security Setting to define the meaning of ROLE

43 Application Access Control 43 This makes a difference when using Authorization Schemes

44 Application Access Control 44 Summary Roles are exported with the application User / Role Mappings are NOT Typically use local user table for additional details ( , first name, ) API provided: APEX_ACL Data dictionary views for viewing and modifying the data (INSERT, UPDATE, DELETE on APEX_APPL_ACL_USERS)

45 Application Settings 45 Maintain application specific configuration settings, e.g. Environment, servers,... Why? Application and Source Code should be identical between environments, specific go into config table

46 Application Settings 46 On Upgrade Keep Values => respect the value upon upgrade

47 Templates 47 Manage Templates as part of the application

48 Templates 48

49 Templates 49 Send via API begin apex_mail.send ( p_to => 'dietmar.aust@opal-consulting.de', p_template_static_id => 'TEST1', p_placeholders => '{' ' "CUSTOMER_NAME":' apex_json.stringify( 'Dietmar' ) ',"ITEMS_ORDERED":' apex_json.stringify( 6 ) ',"MY_APPLICATION_LINK":' apex_json.stringify( '' ) ',"ORDER_DATE":' apex_json.stringify( '' ) ',"SHIPPING_ADDRESS_LINE_1":' apex_json.stringify( '' ) ',"SHIPPING_ADDRESS_LINE_2":' apex_json.stringify( '' ) ',"SHIP_TO":' apex_json.stringify( '' ) '}' ); end;

50 Templates 50

51 Templates 51 Just generate the HTML via the API declare l_subject varchar2( 4000 ); l_html clob; l_text clob; begin apex_mail.prepare_template ( p_static_id => 'ORDER', p_placeholders => '{ "ORDER_NUMBER": 5321, "ORDER_DATE": "01-Feb-2018", "ORDER_TOTAL": "$12,000" }', p_subject => l_subject, p_html => l_html, p_text => l_text ); end;

52 Templates 52 Manage Templates as part of the application Good separation of Templates and data in placeholders Easy to use No complex logic supported

53 Items and Regions 53

54 Tree Region - Enhancements 54 The Advanced: JavaScript Initialization Code attribute is supported. JSDoc for Tree Region, easier to customize the tree Support Dynamic Action Event: Selection Change [Tree]. Advanced Config option (nodeselector) to support checkbox selection. Tree region now supports the apex.region API => but AJAX REFRESH is still not possible! Copy selection to clipboard.

55 'Text with Autocomplete' item type using Oracle JET 55 Re-Implementation of the item type Text with Autocomplete based on Oracle JET APEX 5.1 APEX 18.1

56 'Text with Autocomplete' item type using Oracle JET 56 Advantages: Improved accessibility Lazy loading with cache Minimum search characters

57 Responsive Rich Text 57 Responsive Rich Text editor - automatically adjusts to the region width.

58 Responsive Rich Text 58 Feature can be turned off in Shared Components > Component Settings Initially turned off for imported / upgraded applications

68 SQL Workshop 68

69 SQL Workshop > QuickSQL 69 QuickSQL is now integrated, used to be a packaged app

70 SQL Workshop > QuickSQL 70

71 SQL Workshop > Sample Datasets 71 Sample Datasets

72 SQL Workshop > Sample Datasets 72 Sample Datasets very good to help with training and troubleshooting

73 Packaged Applications 73

74 APEX_PKG_APP_INSTALL 74 Pre 5.2 Install, upgrade and delete packaged applications on the command line: declare l_app_id number; begin -- Install l_app_id := APEX_PKG_APP_INSTALL.install( p_app_name => 'Sample Trees', p_authentication_type => 'NATIVE_APEX_ACCOUNTS', p_schema => 'DAUST_DE' ); end;

75 APEX_PKG_APP_INSTALL 75 Great for automatically installing all packaged applications after a patch to look for gems or upgrade all applications at once. Currently (not yet) officially supported but used by Oracle in the cloud. Data Dictionary View APEX_PKG_APPS

76 Install Packaged Applications 76 Allow Modify Other Applications in security settings
