1  –  ALIAS aliasname

    When attached to multiple databases, the aliasname is required to
    direct the ALTER command to the appropriate database.

2  –  COMMENT_IS

    Adds a comment about the profile. SQL displays the text of the
    comment when it executes a SHOW PROFILES statement. Enclose the
    comment in single quotation marks ( ') and separate multiple
    lines in a comment with a slash mark (/).

3  –  DEFAULT_PROFILE

    Alters the special profile RDB$DEFAULT_PROFILE. This profile
    will be used by any user who is not assigned a profile using the
    PROFILE clause of CREATE or ALTER PROFILE.

4  –  DEFAULT_TRANSACTION

    DEFAULT TRANSACTION provides a default transaction for the user.
    By default, Oracle Rdb starts a READ WRITE transaction if none is
    explicitly started. Use the DECLARE TRANSACTION or START DEFAULT
    TRANSACTION statement to make use of this definition. You can
    override this clause with a DECLARE or SET TRANSACTION statement.

                                   NOTE

       Oracle Rdb does not permit the RESERVING or EVALUATING
       clauses to appear in the default transaction.

5  –  LIMIT_CPU_TIME

    Syntax options:

    LIMIT CPU TIME | NO LIMIT CPU TIME

    LIMIT CPU TIME sets the maximum CPU time that can be used by the
    query compiler. The keyword DEFAULT indicates that no value is
    defined by this profile and is equivalent to NO LIMIT CPU TIME.

    If a numeric value or the keyword UNLIMITED is specified then
    this value will be used even when the SET QUERY LIMIT CPU TIME
    statement is present in the session, or when the logical name
    RDMS$BIND_QG_CPU_TIMEOUT is defined.

    NO LIMIT CPU TIME is the default. Units can be specified as
    seconds or minutes.

6  –  LIMIT_ROWS

    Syntax options:

    LIMIT ROWS | NO LIMIT ROWS

    LIMIT ROWS sets the maximum number of rows that can be returned
    by a query started by the user. The keyword DEFAULT indicates
    that no value is defined by this profile and is equivalent to NO
    LIMIT ROWS.

    If a numeric value or the keyword UNLIMITED is specified then
    this value will be used even when the SET QUERY LIMIT ROWS
    statement is present in the session, or when the logical name
    RDMS$BIND_QG_REC_LIMIT is defined.

    NO LIMIT ROWS is the default.

7  –  LIMIT_TIME

    Syntax options:

    LIMIT TIME | NO LIMIT TIME

    LIMIT TIME sets the maximum elapsed time that can be used by the
    query compiler. The keyword DEFAULT indicates that no value is
    defined by this profile and is equivalent to NO LIMIT TIME.

    If a numeric value or the keyword UNLIMITED is specified then
    this value will be used even when the SET QUERY LIMIT TIME
    statement is present in the session, or when the logical name
    RDMS$BIND_QG_TIMEOUT is defined.

    NO LIMIT TIME is the default. Units can be specified as seconds
    or minutes.

8  –  negated-attributes

    Syntax options:

       NO DEFAULT TRANSACTION
       NO TRANSACTION MODES
       NO LIMIT CPU TIME
       NO LIMIT ROWS N
       NO LIMIT TIME

    These options explicitly record the negated attribute setting.
    These clauses will remove the current setting of any clause being
    negated.

9  –  RENAME_TO

    Changes the name of the profile being altered. See the RENAME
    statement for further discussion.

10  –  TRANSACTION_MODES

    Syntax options:

    TRANSACTION MODES | NO TRANSACTION MODES

    TRANSACTION MODES provides the list of allowable transactions
    for this user. Please see the SET TRANSACTION MODES clause of the
    CREATE DATABASE and ALTER DATABASE statements for more details of
    txn-modes.

    The transaction modes specified may include modes disabled
    for all database users by CREATE, IMPORT, or ALTER DATABASE
    statements. However, only the subset allowed by both profile and
    database settings will be used. For instance, if the database
    specifies (READ ONLY, SHARED READ, PROTECTED READ) and the
    profile specifies (READ ONLY, SHARED), the session will be
    allowed the subset (READ ONLY, SHARED READ).

    See the description in the CREATE PROFILE statement for all other
    attributes supported by ALTER PROFILE.
