Hello,

the module is writing to database only at shutdown, otherwise it keeps everything in cache -- just in case you expected to see some records in database at runtime. However, I think there was an issue that even at shutdown the module didn't write back to database. Please fetch the latest git branch 3.1 and try again for this purpose.

Thanks,
Daniel

Hi,

did anyone run into similar problems or have successfully set up IMC module with mysql? Can you please share your know-how on the subject?

Besides issue described below, I also had several other issues, but I think they all might be related to the fact that my rooms and members are only stored in cache, but not in the database. To repeat, this is really strange behavior because all other modules that I'm using write to the database without a problem.

Best regards
Ozren

Hi all,

I'm trying to configure IMC module and get it to work properly but I've run into problems with saving IMC module data to mysql database.

I'm using following code provided in IMC module documentation:
 
modparam("imc", "db_url", DBURL)

## route block ###
        if(is_method("MESSAGE") && (uri=~ "sip:chat-[0-9]+@") || (uri=~ "sip:chat-manager@")) {
                xlog("L_INFO", "going to imc: F [$fu] T [$tu] B [$rb]\n");

                if(imc_manager())
                        sl_send_reply("200", "ok - imc_manager()");
                else
                        sl_send_reply("500", "command error");
        exit;
        }

I am creating chat room with following message sent to chat-manager@abc.hr: "#create chat-111"

DEBUG log returns following:
May 30 18:01:23 ser-test /usr/local/kamailio-ozren/sbin/kamailio[13225]: INFO: <script>: going to imc: F [sip:oz@abc.hr] T [sip:chat-manager@abc.hr] B [#create chat-111]

"./kamctl fifo imc_list_rooms" returns following:
ROOM::  URI=sip:chat-111@abc.hr MEMBERS=0 OWNER=sip:oz@abc.hr

"./kamctl fifo imc_list_members sip:chat-111@abc.hr" returns following:
ROOM:: sip:chat-111@abc.hr NR_OF_MEMBERS=1
        MEMBER:: sip:oz@abc.hr

However, that data is not persisted/saved in the imc_rooms and imc_members tables in the database. Any clues what might be the problem here?

Any help is greatly appreciated.

Best regards,
Ozren Lapcevic

PS
I'm runing Kamailio 3.1.4 with default cfg file with enabled mysql, multidomain, usrlocdb, auth and NAT. I can register clients, establish calls, send IMs, etc. imc_rooms and imc_members tables were created when kamailio was installed. I've also checked imc-create.sql script and tables are correctly created.

The same DBURL used for imc is also used for auth_db, domain and usrloc modules and I haven't experienced any problems with those modules and database connection/persistence. domain, location, version and subscriber tables are correctly populated.

I'm not getting any errors from imc_manager(), it returns 200 OK. I can't trace any errors in DEBUG related to problems with mysql database.
