[Users] OpenSER MySQL Updates - Weird

[Norman Brandinger]

Douglas,

Below is Bogdan's previous response to you:

<snip>
all db_mods from 0 to 2 use mem cache - the difference is when the DB is
updated with changes from cache. in mod 1 the changes from cache are
immediately written into DB.

the only non-cache db mod is 3, but this is available only in the devel
branch - read carefully the docs to understand the implications of this mod.
</snip>

As you can see, he didn't say that db mode 3 is required in your 
situation.  He was just briefly explaining the option and steering you 
to the docs for more detailed information.  I don't think that the devel 
CVS branch is called OpenSER 1.1 but that's just a matter of semantics.

Anyway, getting back to your question:

If you google "multiple SER site:mail.iptel.org" you will find a 
discussion of your problem along with suggested solutions.

A thread along these lines is, for example: 
http://mail.iptel.org/pipermail/serusers/2003-November/003847.html

<from the above thread>
We have multiple SER servers all accesing the same database.  We had to
introduce a new "location" table for each instance of SER.  So for example
we have a main SER server which acceses the standard "location" table and we
have another SER as RTPProxy which uses a table called "location_proxy".  We
just created that custom table using the structure of the regular "location"
table.

Has been working great for us for several months.
</from the above thread>

I have found that searching mail.iptel.org will often provide answers to 
many questions.  Note that the above example thread was posted back in 2003.

Regards,
Norm
