Yes !!! it works .... ! it is not necessary to modify the iBatis
source code, in order to implement a new Cache Controller !.
In my case, it works only if I create a typeAlias :
<alias>
<typeAlias alias="MEM"
type="MemcachedCacheController.MemcachedController,
MemcachedCacheController"/>
</alias>
<cacheModels>
<cacheModel id="MyCache" implementation="MEM" >
<flushInterval hours="24"/>
<flushOnExecute statement="insert"/>
<property name ="minutes_standard_expire" value="1"/>
<property name ="ServerList" value=" .... "/>
</cacheModel>
Thanks Ron,
now I can improve my cache provider, without modifing ibatis source code.

PS. for newbies : in sqlmap.confg you have to set validateSqlMap to
false, in order to disable the xml validation with xsd file.
<setting validateSqlMap = "false"/>

Subject: RE : Re: distributed cahing/iBATIS.Net
Hi all,
about caching in iBATIS, I've downloaded memcacheddonet library and I've find
how someone can write an ICacheController as Ron's last post hereafter. But, my
question is how can I, after writing MemcachedCacheController as Ron did, make
iBATIS uses this controller instead of the default ones: LRU, MEMORY and FIFO.
I've seen SqlMap.xsd it recognizes only LRU, MEMORY and FIFO. But, as I saw in
that file, I could insert another cache implementation like MC for
MemcachedCacheController . The problem is that somewhere it is asked to provide
the implementation type as type alias, so where can someone tell iBATIS to use
MemcachedCacheController ?
Thanks,
Tite
Ron Grabowski <[EMAIL PROTECTED]> a écrit :
The ICacheController interface only has a few members to it. I didn't see
anything in the MemcachedClient about removing multiple keys.
I haven't tested the code below but I'm able to run the MemcachedBench program
against a win32 build of memcached:
http://jehiah.com/projects/memcached-win32/
I think the ICacheController should have a Shutdown member so 3rd party caches
can clean up when the application shutsdown.
Of course all the properties on the pool object should be settable by
the properties argument. The properties argument should also have a key
to prefix items put into the cache so IBatisNet plays nice with other
programs using the cache. It should be possible to also integrate the
FlushInterval construct into this implementation.
// untested - inspired by Memcached.MemcachedBench.MemcachedBench
public class MemcachedCacheController : ICacheController
{
private SockIOPool pool;
private MemcachedClient memcachedClient;
public object this[object key]
{
get { return memcachedClient.Get(Convert.ToString(key)); }
set { memcachedClient.Set(Convert.ToString(key), value); }
}
public object Remove(object key)
{
return memcachedClient.Delete(Convert.ToString(key));
}
public void Flush()
{
// empty
}
public void Configure(IDictionary properties)
{
string servers = Convert.ToString(properties["server"]);
pool = SockIOPool.GetInstance();
pool.SetServers(servers.Split(','));
pool.InitConnections = 3;
pool.MinConnections = 3;
pool.MaxConnections = 5;
pool.SocketConnectTimeout = 1000;
pool.SocketTimeout = 3000;
pool.MaintenanceSleep = 30;
pool.Failover = true;
pool.Nagle = false;
pool.Initialize();
memcachedClient = new MemcachedClient();
memcachedClient.EnableCompression = false;
}
}

I've done some fooling around with memcached... I still haven't looked into how
to write a custom cache provider for ibatis though. If no one's done it by the
time I get there, then I'll probably do it :)

Someone needs to write an IBatisNet cache client for memcached:

There is a closed source solution called NCache but its probably $$$.

Hi evry body,
I am new in using iBATIS as a data mapper in the project. But it works well. It
allow me to have a better architecture of my application so it isolates
correctly the data access. But my concern about it is distributed caching. Does
iBATIS allows this kind of stuff or is there an open source solution that can
be used with iBATIS like OSCache for iBATIS java?
