SET Command
DBMAXDAYSTOPURGE days
Defines the maximum number of old daily filesets that will be purged at each
database cleanup rollover. This option limits the number of daily file sets that will
be purged for a given rollover.
days
specifies the number of daily purge file attempts for each entity. A value other than
1 causes the rollover algorithm to reattempt file purges on subsequent days. A
days value other than 1 allows a rolled-over file that was open for analysis to have
purge attempts for that file to occur on subsequent days. Thus if days were 3,
there would be 3 daily attempts to purge the file for each entity. The value of days
should typically not exceed 7. The maximum value for days is 60.
Examples
Consider the following settings:
+ SET DBMaxDays 7
+ SET DBMaxDaysToPurge 1
+ SET DBRolloverSubvolPrefix ASAP
+ SET DBRolloverFilePrefix Z
Given these above settings, a database rollover that occurred on January 8, 2004
would purge the following fileset:
- ASAP2003.Z1231*
Using the same settings above, with DBMaxPurges set to 3 instead. A rollover that
occured on January 8, 2004 would attempt to purge the following filesets:
- ASAP2003.Z1231*
- ASAP2003.Z1230*
- ASAP2003.Z1229*
DBROLLOVERSUBVOLPREFIX prefix
prefix
This option defines the first 1 through 4 alphanumeric characters of the
database rollover subvolume name. The option is only meaningful when SET
RETAIN ROLLOVER is specified. For more details on SET RETAIN options,
see HELP SET RETAIN.
The Default value is ASAP. Thus if SET RETAIN ROLLOVER is specified, and
SET DB equals $DATA.ASAPDB.DB, and SET DBRolloverSubvolPrefix is
ASAP, rollover files will be named using the following subvol-file template:
$DATA.ASAPyyyy.ZmmddEEE
