I've been hosting a site with a hosting service that only let me use one
database. Now I'm trying to get this site running on my home windows
machine using FoxServ (a combination PHP/MySQL install package for Windows).
In anticipation of future database fragmentation, I've split my session
table into a separate database. When this site goes live commercially I
intend to have multiple database servers and probably one that is dedicated
to session data. So my session classes look like this:
class SessionDB extends DB_Sql
{
var $Host = 'localhost';
var $Database = 'session';
var $User = 'myusername';
var $Password = 'mypassword';
}
class Bank_CT_Sql extends CT_Sql
{
var $database_class = 'SessionDB'; ## Which database to
connect...
var $database_table = 'active_sessions'; ## and find our session
data in this table.
}
class Bank_Session extends Session
{
var $classname = 'Bank_Session';
var $cookiename = ''; ## defaults to
classname
var $magic = 'Umuarama'; ## ID seed
var $mode = 'get'; ## We propagate session
IDs with cookies
var $fallback_mode = 'get';
var $allowcache = 'no';
var $lifetime = 259200; ## 0 = do session
cookies, else minutes
var $that_class = 'Bank_CT_Sql'; ## name of data storage
container
var $gc_probability = 25;
var $gc_time = 720;
var $auto_init = '../include/setup.inc';
}
But when I try to log in I get an error message on the login form page that
displays after the login form itself. It says:
Database error: Invalid SQL: update active_sessions set
val='QmFua19TZXNzaW9uOiR0aGlzLT5pbiA9ICcnOyAkdGhpcy0+cHQgPSBhcnJheSgpOyAkdGh

MySQL Error: 1146 (Table 'bank_user.active_sessions' doesn't exist)
Session halted.
It looks like it is trying to save session info in the wrong database. But
I put some debugging code into ct_sql.inc at line 97 just before the query
tries to get executed to see what database name and host the class is
actually set to. It is set to "session" and not "bank_user" (which is
another database on the server). Is this a problem in phplib or in php
itself? It seems really strange that the DB_Sql class would try to connect
to the wrong database.
Any ideas or help would be greatly appreciated.
Thanks,
Carl Youngblood

Cannot help, but:
Yes, I also have this problem! I've "fixed" it for myself in querying
the session table in the proper database before closing with page_close().
This is a bloody hack but works fine for me at the moment. ;-)

I hope sthat's a really high traffic site to require spliting into
multiple physical servers. I think it might be overkill but.. what the
hey :) If you're looking for speed, use a shmem partition for session
data. Super fast and if done correctly, the removal of the session data
shouldn't be an issue becasue all your sessions would have closed with the
server shutdown :) (eg: use the user object instead of regurgitating old
sessions or setting a session life time for some unreasonable anout of
time)
Anyway, this is an age old problem that lives in php and conneciton
pooliing, the answer is to have different username / apssword paris for
each different database you wish to access.
You could also poll the correct db, before page_close() but that's (as
stated before) a hack.
