■ Conventions: Fonts and symbols

The following table explains the fonts used in this manual:

Font

Convention

Bold

Bold type indicates text on a window, other than the window title. Such text includes menus, menu options, buttons, radio box options, or explanatory labels. For example:

  • From the File menu, choose Open.

  • Click the Cancel button.

  • In the Enter name entry box, type your name.

Italics

Italics are used to indicate a placeholder for some actual text to be provided by the user or system. For example:

  • Write the command as follows:

    copy source-file target-file

  • The following message appears:

    A file was not found. (file = file-name)

Italics are also used for emphasis. For example:

  • Do not delete the configuration file.

Code font

A code font indicates text that the user enters without change, or text (such as messages) output by the system. For example:

  • At the prompt, enter dir.

  • Use the send command to send mail.

  • The following message is displayed:

    The password is incorrect.

The table below shows the symbols used in this manual for explaining commands and operands, such as the operands used in server definitions.

Note that these symbols are used for explanatory purposes only; do not specify them in the actual operand or command.

Symbol

Meaning

Example

|

In syntax explanations, a vertical bar separates multiple items, and has the meaning of OR.

adb_sql_text_out = {Y|N}

In this example, the vertical bar means that you can specify either Y or N.

[ ]

In syntax explanations, square brackets indicate that the enclosed item or items are optional.

adbsql [-V]

In this example, the square brackets mean that you can specify adbsql, or you can specify adbsql -V.

{ }

In syntax explanations, curly brackets indicate that only one of the enclosed items is to be selected.

adbcancel {--ALL|-u connection-ID}

In this example, the curly brackets mean that you can specify either --ALL or -u connection-ID.

...

In syntax explanations, an ellipsis (...) indicates that the immediately preceding item can be repeated as many times as necessary.

adbbuff -n DB-area-name[, DB-area-name] ...

In this example, the ellipsis means that you can specify DB-area-name as many times as necessary.

{{ }}

In syntax explanations, double curly brackets indicate that the enclosed items can be repeated as a single unit.

{{adbinitdbarea -n data-DB-area-name}}

In this example, the double curly brackets mean that you can specify adbinitdbarea -n data-DB-area-name as many times as necessary.

X

(underline)

In syntax explanations, underlined characters indicate a default value.

adb_import_errmsg_lv = {0|1}

In this example, the underline means that the value 0 is assumed by HADB when the operand is omitted.

~

A swung dash indicates that the text following it explains the properties of the specified value.

adb_sys_max_users = maximum-number-of-concurrent-connections

~ <integer> ((1 to 1024)) <<10>>

In this example, the text following the swung dash means that you can specify an integer in the range from 1 to 1024. If the operand is not specified, the value 10 is assumed by HADB.

< >

Single angle brackets explain the data type of the specified value.

(( ))

Double parentheses indicate the scope of the specified value.

<< >>

Double angle brackets indicate a default value.

■ Conventions: Syntax elements

Syntax element notation

Meaning

<path name>

The following characters can be used in path names:

  • In Linux

    Alphanumeric characters, hash mark (#), hyphen (-), forward slash (/), at mark (@), and underscore (_)

  • In Windows

    Alphanumeric characters, hash mark (#), hyphen (-), forward slash (/), at mark (@), underscore (_), backslash (\), and colon (:)

Note, however, that the characters that can be used might differ depending on the operating system.

<OS path name>

For an OS path name, all characters that can be used in a path name in the operating system can be used. For details about available characters, see the documentation for the operating system you are using.

<character string>

Any character string can be specified.

<integer suffixed by the unit>

Specify the value in a format consisting of a numeric character (in the range from 0 to 9) followed by a unit (MB (megabyte), GB (gigabyte), or TB (terabyte)). Do not enter a space between the numeric character and the unit.

  • Examples of correct specification

    1024MB

    512GB

    32TB

  • Example of specification that causes an error
