[OpenSIPS-Users] Clusterer without a database

Hi All,

For "greater good" I thought it would be interesting to add some clusterer
dialog replication to my OpenSIPs pair.

Specifically I am on 2.4, installed the appropriate clusterer module and
applied the following configuration:

*+# Replication listener*
*+listen=bin: <>*
*+loadmodule "proto_bin.so"*
*+loadmodule "clusterer.so"*
*+# Setup replication cluster*
*+modparam("clusterer", "current_id", 2)*
*+modparam("clusterer", "db_mode", 0)*
*+modparam("clusterer", "current_info", "cluster_id=1,
url=bin: <>") # data about this
*+modparam("clusterer", "neighbor_info",
<>") # data about other node*
*+modparam("dialog", "dialog_replication_cluster", 1)*
*+modparam("dialog", "profile_replication_cluster", 1)*

Once configured I attempted to start the service only to discover that
clusterer will not load without a database module. See below:

*Aug 08 08:55:10 pci-fram-proxy2.x-onsecure.net
<http://pci-fram-proxy2.x-onsecure.net> opensips-m4cfg[30867]: Aug  8
08:55:10 [30867] WARNING:core:solve_module_dependencies: module clusterer
depends on an sqldb module, but none was loaded!*
*Aug 08 08:55:10 pci-fram-proxy2.x-onsecure.net
<http://pci-fram-proxy2.x-onsecure.net> opensips-m4cfg[30867]: Aug  8
08:55:10 [30867] ERROR:core:main: failed to solve module dependencies*

For now I have simply reverted back however I wonder if this is a user
error or a module/documentation error?
