D Object Naming Rules in Oracle Portal

This appendix summarizes the rules that apply to the naming of objects in Oracle Portal. Unless otherwise indicated, names and display names are not case sensitive. In other words, in most cases APP is the same as app.

Table D-1 Object Naming Rules in Oracle Portal

Object Name Display Name

Attributes

  • 256 bytes

  • Must be unique within its page group and the Shared Objects page group

  • Defaults to Display Name minus invalid characters when no value is entered

  • Alphanumeric and underscore (A to Z, a to z, 0 to 9, and _)

  • 256 bytes

  • Any character, except comma

    Commas in attribute Display Names interfere with the display of attributes in search-related selection boxes. This is because commas are used as delimiters between attribute names. For example, an attribute with the Display Name Sales, London, UK, appears as three separate, selectable attributes in search-related selection boxes.

  • Multi-byte characters allowed

Categories

  • 60 bytes

  • Case sensitive

  • Defaults to Display Name minus invalid characters when no value is entered

  • Must be unique among all categories at the same level within its page group.

  • Alphanumeric and underscore (A to Z, a to z, 0 to 9, and _)

  • 240 bytes

  • Any character

  • Multi-byte characters allowed

HTML Templates

  • 50 bytes

  • Must be unique within its page group

  • Multi-byte characters allowed

  • Any character except:

    , & # % \ / : * ? < > | "

With HTML templates, the Template Name doubles as a Name and a Display Name

Items and Portlets

  • 256 bytes or 126 bytes for file names

  • Case sensitive

  • Must be unique within its parent page; when tabs are present, must be unique within a given tab.

  • Multi-byte characters allowed

  • Anything except:

    , & # % \ / : * ? < > | "

  • In the case of uploaded files, defaults to file name; if file name contains illegal characters, defaults to GUID

  • 256 bytes

  • Any character; in the case of uploaded files, defaults to file name if unspecified

  • Multi-byte characters allowed

Item Types

  • 30 bytes

  • Must be unique within its page group and the Shared Objects page group

  • Defaults to Display Name minus invalid characters when no value is entered

  • Alphanumeric and underscore (A to Z, a to z, 0 to 9, and _)

  • 256 bytes

  • Any character

  • Multi-byte characters allowed

Navigation Pages

  • 60 bytes

  • Case sensitive

  • Defaults to Display Name minus invalid characters when no value is entered

  • Must be unique within its page group

  • Multi-byte characters allowed

  • Anything except:

    , & # % \ / : * ? < > | "

  • 256 bytes

  • Any character

  • Multi-byte characters allowed

Page Groups

  • 60 bytes

  • Case sensitive

  • Defaults to Display Name minus invalid characters when no value is entered

  • Must be unique among page groups

  • Multi-byte characters allowed

  • Anything except:

    , & # % \ / : * ? < > | "

  • 256 bytes

  • Any character, except comma

    Commas in page group Display Names interfere with the display of page groups in search-related selection boxes. This is because commas are used as delimiters between page group names. For example, a page group with the Display Name Sales, London, UK, appears as three separate, selectable page groups in search-related selection boxes.

  • Multi-byte characters allowed

Pages

  • 60 bytes

  • Case sensitive

  • Defaults to Display Name minus invalid characters when no value is entered

  • Must be unique among all pages that are at the same level in its page group's page hierarchy.

  • Multi-byte characters allowed

  • Anything except:

    , & # % \ / : * ? < > | "

  • 256 bytes

  • Any character

  • Multi-byte characters allowed

Page Types

  • 30 bytes

  • Must be unique within its page group and the Shared Objects page group

  • Defaults to Display Name minus invalid characters when no value is entered

  • Alphanumeric and underscore (A to Z, a to z, 0 to 9, and _)

  • 256 bytes

  • Any character

  • Multi-byte characters allowed

Parameters

Notes

In Oracle Portal, Name uniqueness is preserved automatically by the addition of a value.

If the Shared Objects page group contains an object that uses the same name as an object that you move to the Shared Objects page group, Oracle Portal appends a value to the Name (internal name) of the moved object. This is to maintain name uniqueness within the page group.

For example, imagine that the Shared Objects page group contains a category named sample_category. Another page group, Division, contains a category that is also named sample_category. You move sample_category from the Division page group to the Shared Objects page group. Oracle Portal appends a value to the moved category, such as sample_category_AABkUWAAJAABpiAAC. You can revise the internal name, but you cannot give it the same Name as any other object in the Shared Objects page group.

The same rule applies when you try to create any object with a Display Name that duplicates another object's Name. Oracle Portal uses an object's Display Name to create the object's (internal) Name. If you enter the Display Name red for an object, and another object already uses the name red. The first object's Display Name will be red, but its Name will have a value appended to it to make it unique, for example, red1.
