Hello again,
I'm currently using successfully QPid C++ Broker and BDB as message store. I
checkouted the qpid BDB module here :
http://anonsvn.jboss.org/repos/rhmessaging/store/trunk/cpp/
I've two questions :
1) I would like to know how I can disable the debug trace when I use the BDB
persisent store in QPid (I've to much traces like bellow and it's realy not
good for my benchmarks) :
2009-feb-23 16:34:10 trace RECV [127.0.0.1:60321]: Frame[BEbe; channel=0;
{SessionCompletedBody: commands={ [39936,39993] }; }]

2) When I want to get the help of the BDB module I get this :
Store Options:
--store-dir DIR Store directory location for persistence
(instead of using --data-dir value).
Required
if --no-data-dir is also used.
--num-jfiles N (8) Default number of files for each journal
instance (queue).
--jfile-size-pgs N (24) Default size for each journal file in
multiples
of read pages (1 read page = 64kiB)
--wcache-page-size N (32) Size of the pages in the write page cache in
KiB. Allowable values - powers of 2: 1, 2,
4,
... , 128. Lower values decrease latency at
the
expense of throughput.
--tpl-num-jfiles N (8) Number of files for transaction prepared
list
journal instance
--tpl-jfile-size-pgs N (24) Size of each transaction prepared list
journal
file in multiples of read pages (1 read page
=
64kiB)
--tpl-wcache-page-size N (4) Size of the pages in the transaction
prepared
list write page cache in KiB. Allowable
values
- powers of 2: 1, 2, 4, ... , 128. Lower
values
decrease latency at the expense of
throughput.
Where are the options to have synchronous / asynchronous IO ? Did I make a
mistake when downlowding the BDB module ? Is there another one ?
Thanks for all
