Oracle Unleashed- P12

Delete Section This section can be very dangerous! The first option here is Remove Repository Objects. This will drop all database objects created for the repository instance. The second option is Remove All Objects. This option will drop ALL objects owned by the repository owner. Again, be aware that objects will be gone after executing one of these two options. The Remove All Objects option is available when a new install option is detected. This could be useful in ensuring the repository owner owns nothing prior to repository installation. It is recommended that the database administrator ensure that objects to be dropped are indeed dropped. Backup Section This section provides for repository specific backup capabilities, outside of the backups performed by the database administrator. The repository manager has the capability of exporting and importing in the following ways: Import: This will use the Oracle IMPORT utility to import tables, views, and packages that belong to the repository from a previously created export file. Export Repository Tables: This will create an export file of all repository tables. (Only the tables!) Export Repository User: This will create an export file of ALL objects owned by the repository owner. Export All User Tables: This will create an export file of ALL TABLES owned by the repository owner. Using the last two export options will provide for objects and tables not created by the Designer/2000 product but owned by the repository owner user ID. Tablespace Selections There are two tablespace selection drop-down list boxes. They are included to allow the repository manager to select tablespaces other than the default tablespace setup for the repository owner. It will also allow for separation of the repository indexes from the repository tables for tuning purposes. This is highly recommended. Buttons The buttons actually initiate actions from the repository management tab screen. The buttons initiate the following actions: Execute: This tells the utility to perform whatever action has been selected. Pre-Check: This tells the utility to check the repository owner's privileges and check the selected tablespaces for the proper amount of space required for the repository to be installed or upgraded. Help: Brings up the online help. NLS: Allows for the setting of a new language used in the Designer/2000 screens and reports. It also allows for Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. additions to the list of languages available. Pin: This will tell the database to keep frequently used packages, used by Designer/2000, in memory for quicker access. This will take up more of the database's SGA though. Unpin: Allows for package swapping in the SGA. (DEFAULT) To PIN the repository packages, the repository owner must have the rights to execute the SYS. DBMS_SHARED_POOL package. This package can be loaded by your DBA via execution of the dbmspool.sql and prvtpool.sql as the user SYS. Privileges Tab This tab screen, as seen in Figure 24.3, is primarily a display of the necessary privileges needed to be a repository owner. If any privilege does not have X in it, the DBA will need to notified prior to installation or upgrade. Figure 24.3. Repository Administration Privileges summary tab screen. There are three buttons available in this tab screen also. These buttons are as follows. Role: Database roles assigned to the repository owner. Show All: Shows all database privileges assigned to the repository owner. Help: Initiates the online help. If the DBA has created specific roles for repository owners and users, this can then be easily seen here. Tablespace Tab This tab screen, as seen in Figure 24.4, shows an overview of the tablespaces the repository owner has access to. This will be an important place for the repository manager to monitor the space requirements of the repository. The utility also identifies the repository owner's default and temporary tablespaces and user quota. Figure 24.4. Repository Administration Tablespace Analysis tab screen. Maintain User Tab This tab screen, as shown in Figure 24.5, is where the internal security is managed for the Designer/2000 products. It does not correspond to database security equivalency in anyway. Thus, a user with read-only privileges here could still access the repository tables via such products as SQL*Plus. Figure 24.5. Repository Administration Maintain User tab screen. User Spread Table Items Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. The Oracle UserName can be selected via the drop-down list box. This will list all users on the database instance. There are two Designer/2000 roles, USER and MANAGER. The USER role is the default, and gives access to all Designer/2000. The exception is that a USER cannot access the Application menu option in the Repository Object Navigator. The MANAGER role has access to all Designer/2000 tools except for Repository Administration Utility. This is only accessible by the repository owner. A MANAGER is also the only user type that can be an application system owner. There are also two modes that can be assigned to users, READ and WRITE. The READ mode gives read-only access to the repository via the Designer/2000 tools. The WRITE mode gives full read and write access to the repository via the Designer/2000 tools. The READ and WRITE modes only affect the Designer/2000 tools internally and do not correspond to user database privileges! Scrolling the user spread table horizontally also shows an editable Description field. Here, the repository manager can put in some meaningful text to identify the repository user. The final item in this spread table is the repository user creation date. This is not directly editable. Privileges will still need to be granted for each application by the application owner. This can be done in the Repository Object Navigator under the Application | Grant Access menu option. Buttons The buttons for this tab screen provide the following actions: Insert: Inserts a new record into the spread table. Delete: Deletes a record from the spread table. Reconcile: Performs the additions, deletions and changes saved in the spread table. Reconciliation must be initiated for changes to take affect. Save: Saves the current spread table. Only available after an insert, delete or modification. Help: Brings up the online help. User Extensibility Tab User extensibility allows organizations to add Element, Association, and Text Types to the repository. These extensions allow organizations to add items that are not currently included. An example would be to add a text type that identifies a contractor or project number. This text type then could be added to the Application System element type. An example of the User Extensibility tab can be seen in Figure 24.6. Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Figure 24.6. User Extensibility tab screen. Element Type An element type would be a top level object in an application system. User extensions for the element type can have a short name of E0 - E99. Elements that come as a default for an application in Designer/2000 would be things like: Events ● Entities Tables Modules Association Type An association type would defines the meta-model association between elements. User extensions for the association type can have a short name of A0 - A99. An example of a Designer/2000 supplied association would be such things as: Application Document: Links an Application Systems to Documents. Trigger Column Usage: Links a Database Triggers to Columns. Module Function Usage: Links Functions to Modules. Text Type A text type is basically any object best defined in a textual mode. These text items can be anything needed to better document your system. An example of Designer/2000 provided text items would be: Description PL/SQL Block Where/Validation Condition Extending the Repository The extensions can be added in two ways, which are creating new types or modifying existing types. To add a new type: Select one of the type radio buttons on the left. Fill in the information in the dialogue box for that type. Add any properties or text type usages required. Publish the new type by selecting the Publish button. Submit the DDL (actually updates the Repository Meta-Model). Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Once an extension has been published, it cannot be edited or deleted. The second way to extend the repository is to add new properties or text type usages to existing types. To do this either edit one of the Usrx objects and edit the properties or select the New button and select an existing type to add. Once this has been completed, publish the changes. Once a Usrx extension has been published, only the length, precision, mandatory, and case mode fields can be changed. UE Utilities Tab This tab, as seen in Figure 24.7, provides three options for user extensions. Figure 24.7. UE Utilities tab screen. Convert: Used to convert Case Dictionary 5.0, 5.1, and early releases of Designer/2000 user extensions for use in the Designer/2000 repository. Extract: Used to export user extensions. Load: Used to append previously extracted extensions to the repository definition tables. See the release notes for any problems associated with user extensions that may exist during conversion, extract or load. The Matrix Diagrammer The matrix diagrammer is a designer/project leader tool. It is nothing more than a repository reporting tool that will display in a GUI format or provide printed output. Per its name, the reporting done is a matrix style. Thus, there will be rows, columns and a condition to report on. These reports are used to show completion or missing items in the application design process. An example of a matrix diagram is seen in Figure 24.8. Figure 24.8. A matrix diagram. Matrix items for the rows and columns are in a list box of choices, and are the same initially in the new matrix dialogue box. Once something is chosen in either list box, the other list box elements will only show those items that can be reported against. The items that will be shown in the two list boxes are as follows: Assumptions Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Attributes Business Functions Business Units Columns Critical Success Factors Entities Key Performance Indicators Locations Modules Nodes Objectives Problems Relations When both row and column options are chosen, a settings dialogue box will be displayed. Here is where row and column display items are chosen along with any filters and ordering conditions. Next intersection properties of the row and column are chosen. After the settings and filters are completed, the matrix diagram will be generated. Once the matrix diagram is created, row or column items can be drilled down on bringing up the property sheet or the matrix result can be drilled down on bringing up its property sheet. Items in the property sheets can then be edited. The columns and rows of the matrix can be added and deleted, and three different views can be shown based on preferences set. The matrix report can also be printed out, but in some cases the matrix lines will not print. The Repository Object Navigator As in the previous versions of Oracle CASE Dictionary and it's Main Menu, Designer/2000 also provides a tool for viewing any portion, or the entire repository, and launching any of the supplied utilities and design tools. This tool is called the Repository Object Navigator, sometimes referred to as RON. New to this tool is the use of the hierarchy tree display method and the visual basic like property sheet, as seen in Figure 24.9. Figure 24.9. Repository Object Navigator. Startup First the user will either create a new application for the repository by selecting menu option File | New, or by opening an existing application by selecting menu option File | Open. From the initial startup of the Repository Object Navigator, the user has several choices to choose from in the Filter dialogue box, as seen in Figure 24.10. This dialogue will be displayed by default, but can be suppressed by editing the Repository Object Navigator preferences. Figure 24.10. Repository Object Navigator Filter dialog box. Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. The filters shown will turn on and off the viewing of specified object types. Using these filters can help keep unnecessary information from being displayed to designers. These filters are displayed as check boxes and filter the following: Show User Extensions: Selecting this check box will display any user-defined repository extensions, as defined in the Repository Administration Utility. Show BPR Objects: Selecting this check box will cause objects defined in the Process Modelling stage to be displayed. Show Analysis Objects: Selecting this check box will cause objects defined in the Systems Modelling stage to be displayed. Show Design/Implementation Objects: Selecting this check box will cause objects defined in the Systems Design stage to be displayed. Show "Owned By"Associations Only: Selecting this check box will cause only ownership associations to be displayed. Creating New Applications The user will be placed at the top of the hierarchy tree in the repository object navigator and prompted for the new application's name. The new application name can be up to fourteen characters in length. The name should be meaningful, and cover the entire scope of the application. At this point, the initial application properties should be completed in the property sheet even thought only the name is required. Opening Existing Applications The open application dialogue is displayed and will list all applications available in the repository, application versions, and related user security assigned for the application. The user can also specify read-only mode if no changes are intended to be made. The open application dialogue can be seen in Figure 24.11. Figure 24.11. Repository Object Navigator Open Application dialog box. If multiple applications are opened, each will have its on application window available. Viewing and Preferences There are two child windows that will be initially visible in the Repository Object Navigator's main window. The first is always available when an application is open, which is the Application Hierarchy Tree window. The second, the Properties Window, is optional. There are four different colors used to identify items as Normal items, Error/Mandatory items, Modified items, and Shared/Non-Editable items. These colors can be modified in the user preferences. Think of the hierarchy tree as being rows or records of information in the repository. Think of properties being the actual columns that makeup these rows. Navigating the Hierarchy Tree The standard look and feel of the Designer/2000 and Developer/2000 products will use a hierarchy tree were appropriate. The Repository Object Navigator's hierarchy tree can be seen in Figure 24.12. The tree can be split into to two views by Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. using the split bar located just above the window's vertical scroll bar. Figure 24.12. Repository Object Navigator hierarchy tree. Tree items can be expanded one at a time by either mouse click on the preceding colored +, or by selecting the object and using the Navigator | Expand menu option. Collapsing tree branches back can be done by mouse click on the preceding -, or by selecting the object and using the Navigator | Collapse menu option. The entire hierarchy tree can be expanded or collapsed by using the Navigator | Expand All and Navigator | Collapse All menu options. Objects can be added to the various object types selecting the object type and using the + button on the toolbar, or by using the Edit | Create menu option. Objects can be deleted from object types by selecting the object, and by using the x button on the toolbar or using the Edit | Delete menu option. The Property Sheet Selecting an object on the tree will cause the object's properties to be shown in the properties window, where applicable, if the properties window is open. In the properties window, the details about the object will be displayed and can be added or modified directly here. An example property sheet can be seen in Figure 24.13. Figure 24.13. Repository Object Navigator property sheet. All editing will be done by selecting the property and using the supplied edit method at the top of the property sheet. The edit methods will be either a plain edit field, a list box, or an edit box with a bubble button to the right which can be selected to bring up an editor window. A new property sheet can be opened by selecting the Window | New Property Sheet menu option. Currently, all property sheets open showing only the properties to the currently selected object. Thus, you can only compare properties using the Union/Intersect button and highlighting multiple objects. The Toolbar The Repository Object Navigator provides an iconic toolbar just below the menu to provide mouse shortcuts that map directly to menu items for repository actions. The tool bar can be seen in Figure 24.14. Figure 24.14. Repository Object Navigator Toolbar. Holding the mouse cursor above the button for a short period of time will cause bubble help dialogues to appear describing the button's action. Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. From left to right the buttons perform the following actions: Open an existing application. Save/Commit all changes to the repository. Find Next string occurrence in the hierarchy tree. Find Previous string occurrence in the hierarchy tree. Undo all outstanding changes. Create Object. Delete Object. Copy Properties helps duplicate like properties. Paste Properties updates property sheet with copied properties. Requery the repository tables. Expand one. Collapse one. Expand all. Collapse all. Mark an object, such as a bookmark. Go to a marked object. Go to a referenced object. Context-sensitive help on next mouse-clicked item. The Menu The menu can provide for initiating all actions available in the Repository Object Navigator. The menu also provides a driver for initiating any of the other Designer/2000 tools. File Menu Option The file menu provides basic application and repository actions. The file menu options are described in Table 24.1. Table 24.1. File menu options.
