Attributes assigned by the access method

The access method records the following member attributes:

CREATION-DATE and CREATION-TIME

MODIFICATION-DATE and MODIFICATION-TIME

ACCESS-DATE and ACCESS-TIME

STORAGE-FORM

SECONDARY-NAME and SECONDARY-ATTRIBUTE

Member size


(1)

(2)

(3)



(4)

(1):

In the case of delta members, this date is the same for all deltas and refers to the
time at which the initial data was generated.

(2):

The MODIFICATION-DATE operand of the MODIFY-ELEMENT-ATTRIBUTES
statement is used to specify whether this time stamp is to be updated.

(3):

This time stamp is recorded only if MODIFY-LIBRARY-ATTRIBUTES ...,ACCESS-
DATE=*KEEP has been set for the library.
Only after this setting has taken effect can members have an access date and time.
Except for accesses via Remote File Access (RFA), no write privilege for the library
file is required to have access dates and times recorded. If you wish to have access
dates and times recorded when accessing via RFA but have no write privilege for
the library file, your access request will be rejected.
For libraries on NK disks, PLAM determines the scope of any partial backup. The
backup granulate is a single member. Members for which only the access date has
changed are not included in partial backups. In the event that a backup is restored,
these members are given the time of the last full backup of the library file as an
access date.

(4):

In the case of delta members, the size refers to the memory allocation of the whole
delta tree and not to that of the individual versions.
