Are you saying the * server does NOT TRY to re-establish the BD connection ?
Does your whole * SERVER freeze ?
If NOT, what happens to you CDR records ?

That's not true. The MYSQL app generally uses multiple connections,
one
for each channel. The only way one might use only a single
connection is
by using a global variable to store a single connection id, but that
method
is not documented anywhere, AFAIK.
|
You talk about the Mysql APP, but is this the case with the Realtime
driver as well?
|
No, the native Realtime driver uses a single connection. The ODBC
Realtime
driver generally uses a single connection but can be configured to
use a
separate connection for each query.
|
So, we're back to where we started. A developer that can help us with
a connection
pool or a separate connection for each query would be a Nice Thing (TM).
|
What issues are you specifically seeing that merit using multiple
connections?
|
I can specify an issue that would merit multiple connections, if the
link to your db goes away Asterisk likes to freeze writing CDRs.
I have a few remote * servers that this happens to. My solution so far
has been to record CDR's to a local DB and then have a
perl script that attempts to move them over to my transaction DB. I
would suggest this solution to anyone who depends on their CDR records.

I would not run MySQL on the local box. I would simple use Asterisk's
csv CDRs and then use some script to import the CSVs into a database
residing on another server using some sort of script. Depending on
your needs, you could probably run that during low call volume. I
also think that you adapt the free queue_log to database script by
Queuemetrics to do what you want on the fly.
Thanks,
Steve Totaro |

The MySQL Realtime driver _does_ reconnect.
(Search for mysql_reconnect() in res_config_mysql.c)

Same thing with cdr_addon_mysql.c - it tries to reconnect.
When there is no connection it writes the CDRs to a file and as
soon as it successfully reconnects stores them in the database.

We're using a custom script for the queue_log -> db import
in Gemeinschaft as well. But I'm not really happy with that.
You need to run such a script at least once a minute to get
real-time statistics for the GUI etc. Everything could be
much nicer if Asterisk wrote the queue log into the database
directly.
As an alternative solution you can use a named pipe. But
Asterisk is not prepared to handle the broken pipe error
which occurs if your script should ever fail to read from
the pipe.
