[Users] connection pooling with unixodbc

[Papadopoulos Georgios]

hello all
 
I am loading the following 10 modules that use an oracle database
through unixodbc. 
modparam("usrloc|acc", "db_url", "unixodbc://user:pass@/OracleODBC-10g")
modparam("auth_db|alias_db|uri_db|group|permissions|lcr|domain",
"db_url", "unixodbc://user:pass@/OracleODBC-10g")
modparam("avpops", "avp_url", "unixodbc://user:pass@/OracleODBC-10g")

 
In my config I have fork=yes and tcp is enabled
 
With 5 listen addresses and 
children=1 : 10 connections in the database.
children=2 : 16 connections 
children=3 : 22 connections  
 
With 4 listen address and 
children=1 : 9 connections in the database.
children=2 : 14 connections 
children=3 : 19 connections
 
Could anyone help me understand the relation between listen addresses,
number of children and number of modules that use the db?
Also these numbers are the same whether I use MySQL both through the
mysql module and the unixodbc module. Looking into the code, it seems
like there is connection pooling into the unixodbc module. However I get
all these connections. What am I doing wrong?
 
thank you for any help
 
George
