CHANGE PHRASE

Change the password or password phrase recorded by an external security manager (ESM) for a specified user ID.

CHANGE PHRASE

Conditions: INVREQ, LENGERR, NOTAUTH, USERIDERR

This command is threadsafe.

Description

A user ID can have both a password and a password phrase. If PHRASELEN is between 1 and 8 characters, the phrase is treated as a password. If the length is between 9 and 100 characters, it is treated as a password phrase. You cannot use a 1- to 8-character password to change a password phrase. Similarly, you cannot use a 9- to 100-character password phrase to change a 1- to 8-character password.

Unlike the SIGNON command, CHANGE PHRASE does not depend upon the principal facility; therefore, it can be issued in non-terminal environments such as Web applications and APPC sessions.

Attention: To ensure that passwords are not revealed in system or transaction dumps, clear the password or password phrase fields on the EXEC CICS commands that have a password or password phrase option as soon as possible after use.

Options

Options ESMRESP and ESMREASON return the response and reason codes, if any, from the ESM.

ESMREASON(data-area): Returns the reason code, in a fullword binary field, that CICS® receives from the ESM.
If the ESM is RACF®, this field is the RACF reason code.
ESMRESP(data-area): Returns the response code, in a fullword binary field, that CICS receives from the ESM.
If the ESM is RACF, this field is the RACF return code.
NEWPHRASE(data-area): Specifies an optional 1- to 8-character new password or a 9- to 100-character new password phrase required by the ESM. The password is changed only if the current password is correctly specified. The password phrase is changed only if the current password phrase is correctly specified.
If the ESM does not allow mixed case passwords, the 1- to 8-character password is converted to uppercase.
NEWPHRASELEN(data-area): Specifies the length, as a fullword binary value, of the new password or password phrase.
PHRASE(data-area): Specifies the current password or password phrase of the specified user ID.
If the ESM does not allow mixed case passwords, the 1- to 8-character password is converted to uppercase.
PHRASELEN(data-area): Specifies the length, as a fullword binary value, of the current password or password phrase.
USERID(data-value): Specifies the user ID of the user whose password or password phrase is being changed.
The user ID supplied is converted to uppercase.
