| Acceptable values: | NO, YES, EXT |
|---|---|
| Default: | NO |
| Update: | option 8 on panel DSNTIPB |
| DSNZPxxx: | DSN6ARVP TSTAMP |
- NO
- The archive data set name does not contain a timestamp.
- YES
- The maximum allowable length of the user-controlled portion of
the archive log prefix is reduced from 35 characters to 19 characters.
This reduction in size permits the 16-character date and time qualifiers
(timestamp) to be added to the archive log data set prefix. The timestamp
format is as follows:
where:.Dyyddd.Thhmmsst,- D
- is the letter D.
- yy
- is the last two digits of the year.
- ddd
- is the day of the year.
- T
- is the letter T.
- hh
- is the hour.
- mm
- is the minutes.
- ss
- is the seconds.
- t
- is tenths of a second.
- EXT
- The archive data set name contains a timestamp with an extended date
component in the format:
A value of EXT in this field causes the lengths of the values that are entered for field COPY 1 PREFIX and field COPY 2 PREFIX to be audited to ensure that neither exceeds 17 bytes (19 bytes for other settings of TIMESTAMP ARCHIVES)..Dyyyyddd.
