I have problems with the product queue, I think that people that are
using ldm since long time can help me. The file ldm.pq is too big, I
want to clean it and I don't know how to do it. I delete the file using
ldmadmin delqueue and create again with ldmadmin mkqueue, but the file
returns with the same size. I stop and start ldm and nothing happens. I
use ldmadmin clean, but I think it's not the problem, nothing happens. I
read a lot about this product queue and how to work with it, but it is
not clear for me how to take data from it and how to delete information
in it. Can someone help me to find the problem? Thanks
The LDM queue file is a fixed file size based on what you have set in your
etc/ldmadmin-pl.conf file (look at $pq_size). This 'file' can be thought
of as a rotating queue of data slots where products are inserted, deleted,
etc as the running LDM processes see fit. To take data from it, check out
the 'pqcat' command, which you can use to dump out products by matching
the names they are stored in the queue under.
