I made some tests, and I got that server wit processor 1GHz and 250Mb works stable if I insert 10 rows at once in 1 min. At 20,50 rows or more, stability decrease. With word "stability" I mean that Mysql lose connection for a small time. In this time some responses are lost.
Hey people, what do you think about this situation?
how much rows can be inserted in dlr at once?

Thanks spameden  for your reply


"first of all what's the kannel/sqlbox version you're running?"

I'm using kannel - 1.5 and sqlbox - I'm not really sure, I think 0.7;
What's revision you're using? Try using latest revision from SVN.




  "you might need to tweak some settings. "

Really I had set MyIsam all kannel tables. I have changed from MyIsam to
InnoDb. Will familiarize soon with MariaDB too. Do you mean only these two
tweaks?

"check indexes on dlr table as well."I have indexed id column.

Here is my dlr table
CREATE TABLE IF NOT EXISTS `kannel_dlr`(
   `id` INT(11) NOT NULL AUTO_INCREMENT,
   `smsc` VARCHAR(40) DEFAULT NULL,
   `ts` VARCHAR(40) DEFAULT NULL,
   `destination` VARCHAR(40) DEFAULT NULL,
   `source` VARCHAR(40) DEFAULT NULL,
   `service` VARCHAR(40) NOT NULL,
   `url` VARCHAR(255) DEFAULT NULL,
   `mask` INT(10) DEFAULT NULL,
   `status` VARCHAR(40) DEFAULT NULL,
   `boxc` VARCHAR(40) DEFAULT NULL,
   `CampaignID` INT(11) NOT NULL,
   `RelOwnerUserID` INT(11) NOT NULL,
   `RelOperatorID` INT(11) NOT NULL,
   PRIMARY KEY (`id`),
   UNIQUE KEY `id` (`id`),
   UNIQUE INDEX UK_oempro_kannel_dlr_id (id)
) ENGINE = INNODB DEFAULT CHARSET = utf8 AUTO_INCREMENT = 1;

add an index on smsc and ts:

CREATE INDEX smsc_ts ON dlr (smsc,ts);

when DLR arrives kannel looks for it in dlr table and does a DELETE
from dlr where ts=XXX and smsc=XXXX.


I have some questions about this problem:
I run KANNEL under a small VPS, with processor 1Gb and RAM 250Mb
this may be a problem?
how much memory needs for KANNEL+SQLBOX well working?
This might be a problem if you have large amounts of messages in a queue.

Ram 256Mb ? that's certainly not enough if you plan to do billions of
MTs. Our VM runs on 3gb of memory.

Also, you need good upstream SMSC uplinks which could handle large
amounts of messages per second. I'd recommend using transciever mode
and multiple connections.


because sqlbox use tables(kannel_dlr,kannel_sqlbo
x_send_sms) at the same time with me, may be the cause that I don't use 
TRANSACTIONS.
The best way to modify these tables are to use transactions?
The best way is to use InnoDB over MyISAM because its much faster if
tuned properly and failsafe in case of database corruption.

If I want to send billions of SMS needs I do some specific changes under config 
files?
check throughput and max-pending-submits parameters in User Guide and
contact your smsc operators if you need to tune them properly.

check your mysql setup, you might need to tweak some settings.

i'm strongly suggest using InnoDB instead of MyISAM, also take a look
at MariaDB (it's a fork of mysql, very nicely working).

check indexes on dlr table as well.

we've been using kannel to send about millions of sms messages daily
(MT) without any problems.

2013/11/14 dorin <dorinafte...@mail.ru>:
Hello all!
I have a big problem !

I need to send via KANNEL 5000 of SMS.

When I insert into table kannel_sqlbox_send_sms every minute 10 SMS - all
works fine. But this method is very slow
If I try to increase inserting SMS, for example (100SMS) MySql stops
working
and I got this error:

MySQL Error: MySql Error: Couldn't connect to database - Lost connection
to
MySQL server at 'reading initial communication packet', system error: 111

In ideal I wish to do one insert with 5000 rows

Memory,Proccessor is not loaded.
My configuration is SMSBox+SQLBox+BearerBox;

Please give me some Ideas!
