During a recent VOB restore I performed, I noticed that the VOB storage pool (the sdft subfolder) contains several large files, prefixed with tmp_ (for example, myvob.vbs/s/sdft/10/1d/tmp_3996.1)
Turns out these are called ‘unreferenced containers’, or ‘debris’.
This handy little Perl script removes all traces of a view which is irremovable via conventional means – e.g. when the view storage is missing or inaccessible.
The script is design to run on UNIX in an interop environment, but can be easily be adjusted to other cases.
## Usage: perl rmview_by_tag.pl <region> <view tag>
$region = $ARGV;
$region || die "Region must be specified!";
$tag = $ARGV;
$tag || die "View tag must be specified!";
## Detect view UUID
@uuid = `cleartool lsview -l -region $region $tag`;
if (/View uuid/)
s/View uuid: //;
$uuid = $_;
# Remove the tag from the registry
system "cleartool rmtag -view -region $region $tag";
# Unregister the view
system "cleartool unreg -view -uuid $uuid";
# Remove view-related records from all VOBs
system "cleartool rmview -all -uuid $uuid";
