Note that this TOAD DBA Module Guide was prepared in December 2000. New orchanged TOAD features (including TOAD DBA features) since December 2000 arenot reflected in this version of the TOAD DBA Module User's Guide.

For details on base TOAD, including navigation and main windows, refer to theTOAD User's Guide. For details on installing and uninstalling TOAD, refer to theTOAD Getting Started Guide.

Remember, you can always access TOAD Help while in TOAD by pressingthe F1 Key.

Create Menu

The DBA Module adds the following menu items to the Create Menu: Directory,Library, Policy, Profile, Role, Rollback Segment, Snapshot/M-View, andTablespace.

10

DirectoryYou get to this window from the Create > Directory menu item or from the SchemaBrowser > Directory page > Create Directory button.

This window is used to create a new directory object. A directory object is an alias toa directory on the server's file system where external binary large objects (BFILEs)are stored.

You enter the Name and Path. A drilldown button opens a Browse for folderwindow where you can select a directory and click OK and the selected path isautomatically entered in the Path textbox.

The Show SQL button opens a SQL statement window where your Create DirectorySQL statement is displayed. The Clipboard button on the window copies thestatement to the clipboard. The Save to File button opens the Save As dialog whereyou can choose a path and enter a file name.

Chapter 2 Create Menu 11

Library

You get to this window from the Create > Library menu item or from the SchemaBrowser window > Libraries page > Create new Library button.

This window lets you create a new library object. A library object is an alias to anoperating system shared library (like a .DLL) that can be used in SQL or PL/SQL toallow calls to external functions.

Choose a Schema from the dropdown. This will be the schema that owns the library.

Textboxes let you enter the library Name (alias name for the library) and File Name.The Show SQL button displays the SQL Statement window where the CreateLibrary statement is displayed and can be copied via the Clipboard button or savedvia the Save to File button.

12

Policy

You get to this window from the Create > Policy menu item or from the SchemaBrowser window > Policies page > Create new policy toolbar button

This window lets you create a new policy through the DBMS_RLS package. If youdo not have DBMS_RLS you cannot use this function in TOAD. Refer to the Oracledocumentation for more information.

A textbox lets you enter the Policy Name.

A dropdown lets you select the Schema from which you will select the table or view.Radio buttons let you choose either Tables or Views.

A dropdown lets you select the Table (if the radio button selection is Tables) orView (if the radio button selection is Views).

Additional dropdowns let you select the Schema containing the predicate package,Predicate Package, and Predicate Function.

Checkboxes let you select the statement type(s): Select, Insert, Update, Delete.

Another checkbox allows you to Enable the Policy at Creation.

The Execute button Creates the Policy.


Profile

You get to this window from the Create > Profile menu item or from the SchemaBrowser window > Profiles page > Create New Profile button.

This window lets you create a new profile. A profile is a set of limits on databaseresources. If you assign the profile to a user, that user cannot exceed those limits.

14

The Resource Parameters and Password Parameters tabs contain dropdownswhere you can select Default or Unlimited for numerous parameter items.

The Show SQL button opens the QParserBrowser window which displays SQLStrings, SQL Text, Clause Text, and Values.


Role

You get to this window from the Create > Role menu item or from the SchemaBrowser window > Roles page > Create new Role button.

Name

Type in the Name of the Role.

Identification radio buttons

Select the desired identification method

Not Identified

Externally

Globally

16

Rollback Segment

You get to this window from the Create > Rollback Segment menu item or fromthe Schema Browser window > Rollback Segments page > Create new RollbackSegment button.

This window lets you create a new rollback segment. A rollback segment is an objectthat Oracle uses to store data necessary to reverse (undo) changes made bynon-completed transactions.

You enter the Name in the textbox and choose the Tablespace where you want therollback segment created from the dropdown.

Check the Public checkbox if you want the Rollback Segment to be public (availableto any instance). The default is unchecked.

There are dropdowns for Extents and Size.

Initial Extent specifies the size of the object's first extent.

Next Extent specifies the size of the next extent allocated to the object.

Min Extents specifies the total number of extents to allocate when the object iscreated.


Max Extents specifies the maximum number of extents that can be allocated.

Optimal Size specifies an optimal size for the rollback segment.

The Show SQL button displays the SQL Statement window which displays thecreate statement for your new rollback segment. The Clipboard button lets you copythe statement to the clipboard. The Save to File button lets you save the statement.

18

Snapshot/M-View

You get to this window from the Create > Snapshot/M-View menu item or from theSchema Browser window > Snapshots page > Create New Snapshot button.


The Snapshot/MView window lets you create, update, or modify a snapshot (alsoreferred to as a materialized view).

A snapshot is basically a partial (subset) or complete copy of a table. You can setyour TOAD snapshots to be read-only or updateable (which allows users to insert,modify, or delete rows). Snapshots can be stored in the same database as the mastertable or in a different database. Snapshots provide an easy way to copy a table, forexample from corporate to remote offices, so that everyone can have access to thedata without having to access information across a network. So, network traffic isminimized and system performance is maximized. Snapshots can also be used tooffload information.

The dropdown button lets you choose your Schema for the new snapshot.

Name lets you enter the name for the new snapshot.

The Show SQL button opens the SQL Statement window which shows thecorresponding Create SQL statement. You can copy the statement to the clipboardvia the Clipboard button or save it via the Save to File button.

The window has 4 tabs: Snapshot Info, Physical Attributes, Snapshot SubQuery, andPartitions.

Snapshot Info tab
