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

So, are you saying, based on the email you sent (which I just found) that Openser 1.1 and db_mode 3 are REQUIRED in order to support multiple OpenSER systems accessing a common MySQL database?

Posted this yesterday. Didn't get a reply...
Bogdan, thanks for the reply. I'm don't quite understand. I'm using db_mode 1, which the docs say writes all updates immediately to the database. A 'openserctl ul show' still shows cached entries though. Why? Is db_mode 1 supposed to cache at all? Which db_mode should I use so that I can have two or more OpenSER systems safely accessing the same database?
Douglas.
