Lateral TCP Cache error
Hi there,
I set up two tomcat servers in my PC, and deploy my web application.
I sent a HTTP request to Tomcat1 http://lucyl.prenet.net:8080/console/epinSupport/batchSummaryReport.jsf to get Batch report, and saw the batch report data was saved in local cache C:\Temp\JCS_cache1.
Then I sent another HTTP request to Tomcat2 http://lucyl.prenet.net:8888/console/epinSupport/productSummaryReport.jsf to get the product report, and saw the product report data was saved in local cache C:\Temp\JCS_cache2.
After that, I check C:\Temp\JCS_cache1 again, and found the cache has the batch report and product report. but C:\Temp\JCS_cache2 only has product report. I think JCS_cache1 and JCS_cache2 should have both report data. Any idea why?
Here is cache.ccf for web applicate in Tomcat1:

Two cache.ccf is the same except DiskPath.

Great. I'm sorry the remote cache documentation is
not very helpful. I'll improve it this week.

Hi Aaron,
Everything is working now.
Thanks for your help.

Please think a bit about what the configuration is
supposed to accomplish, and the problem should be
clear. You tell one client where to find the others
in the "TcpServers" setting. The "TcpListenerPort" is
the port at which this client listens.
If server 2 is listening to port 1111, the server 1
should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1111
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1110
And server 2 should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1110
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1111
I'd recommend using UDP discovery, which greatly
simplfies these issues.

Re: Lateral TCP Cache - UDP discovery configuration
Posted by Aaron Smuts <as...@yahoo.com>.
Interesting. I was just about to create a config
option, where you can specify a port range. I run
multiple different Tomcat instances on the same boxes,
each running different sets of services. I have to
keep it clear which application will be using which
lateral ports. If I could specify a range of ports,
the cache could just figure it out for itself. . .

I did something like that:
int listenerPort = props.get( Integer.parseInt(
"jcs.auxiliary.TCPIPCACHE.attributes.TcpListenerPort" ) );
for( int i = 0; i < MAX_JVMS; i++ )
{
int offset = new Random().nextInt( MAX_JVMS );
try
{
ServerSocket socket = new ServerSocket( listenerPort + offset );
socket.close();
listenerPort += offset;
LOGGER.debug( "JCS TCP Lateral cache will use listening socket " +
listenerPort );
break;
}
catch( BindException e )
{
LOGGER.debug( "Socket " + ( listenerPort + offset ) + " is in use,
will try another one" );
Thread.yield();
}
catch( IOException e )
{
LOGGER.fatal( "Cannot bind on socket " + ( listenerPort + offset ),
e );
}
}
props.put( "jcs.auxiliary.TCPIPCACHE.attributes.TcpListenerPort", new
Integer( listenerPort ).toString() );
It is not perfect (has racing and starvation issues), but if you start one
JVM at the time, it works pretty well...
P.S. That explains why I use CompositeCacheManager and CacheAccess instead
of JSC cache directly :)

Please respond to Re: Lateral TCP Cache - UDP
"JCS Users List" discovery configuration
<jcs-users@jakart
a.apache.org>
UDP discovery is documented here:
http://jakarta.apache.org/jcs/LateralUDPDiscovery.html
With UDP discovery you don't have to specify the
servers to connect to; instead, they find each other
using the udp discovery port and address. All servers
that you want to be able to find ech other should be
configured to use the same discovery address and port.
You still need to define a TCPListenerPort. If both
of your servers are on the same machine, then this
port must be different on each.
Basically, they learn about each other by UDP. Then
when they find each other they connect to each other
on the tcp listener port.

Re: Lateral TCP Cache - UDP discovery configuration
Posted by emily chen <em...@yahoo.com>.
Hi Aaron,
With your help, now my lateral tcp cache(TCP and UDP) is working now.
I saved cache.cff file to $TOMCAT_HOME/common/calsses, then deployed my web application. All the report data are present in all jcs local cache. If the report data exists in momory, the data will be removed after Tomcat Server is shutdown. If the data was written to disk cache (jcs.auxiliary.DC.attributes.DiskPath=C:\\Temp\\JCS_cache1), then the data still exist in C:\\Temp\\JCS_cache1 after Tomcat is shutdown. Why JCS cannot removed all the data in the local cache(momory and disk cache) when the Tomcat is shutdown?
Is there any way to clear the cache when Tomcat is shutdown?
Many thanks,
Emily

Re: Lateral TCP Cache - UDP discovery configuration
Posted by Aaron Smuts <as...@yahoo.com>.
UDP discovery is documented here:
http://jakarta.apache.org/jcs/LateralUDPDiscovery.html
With UDP discovery you don't have to specify the
servers to connect to; instead, they find each other
using the udp discovery port and address. All servers
that you want to be able to find ech other should be
configured to use the same discovery address and port.
You still need to define a TCPListenerPort. If both
of your servers are on the same machine, then this
port must be different on each.
Basically, they learn about each other by UDP. Then
when they find each other they connect to each other
on the tcp listener port.

Posted by emily chen <em...@yahoo.com>.
Hi Aaron,
I found an example that you post in the mail list: http://mail-archives.apache.org/mod_mbox/jakarta-jcs-users/200606.mbox/%3C20060605162432.73955.qmail@web38715.mail.mud.yahoo.com%3E
But I don't know how do I config the following attributes of Lateral UDP Discovery if I have two Tomcat servers runing in my PC:
jcs.auxiliary.LTCPAIR.attributes.TcpListenerPort=1118
jcs.auxiliary.LTCPAIR.attributes.UdpDiscoveryAddr=228.5.6.1
jcs.auxiliary.LTCPAIR.attributes.UdpDiscoveryPort=6773
jcs.auxiliary.LTCPAIR.attributes.UdpDiscoveryEnabled=true
jcs.auxiliary.LTCPAIR.attributes.Receive=true
jcs.auxiliary.LTCPAIR.attributes.AllowGet=false
jcs.auxiliary.LTCPAIR.attributes.IssueRemoveOnPut=false
jcs.auxiliary.LTCPAIR.attributes.FilterRemoveByHashCode=true
Thanks for your help.

If server 2 is listening to port 1111, the server 1
should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1111
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1110
And server 2 should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1110
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1111
I'd recommend using UDP discovery, which greatly
simplfies these issues.

Re: Lateral TCP Cache error
Posted by Aaron Smuts <as...@yahoo.com>.
Please think a bit about what the configuration is
supposed to accomplish, and the problem should be
clear. You tell one client where to find the others
in the "TcpServers" setting. The "TcpListenerPort" is
the port at which this client listens.
If server 2 is listening to port 1111, the server 1
should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1111
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1110
And server 2 should be configured like this:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1110
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1111
I'd recommend using UDP discovery, which greatly
simplfies these issues.
Cheers,
Aaron

Re: Lateral TCP Cache error
Posted by emily chen <em...@yahoo.com>.
Hi Aaron,
I did a testing, used different port in cache.ccf file, and still got the same error:
cache.ccf for web applicaton in Tomcat1:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1110
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1110
cache.ccf for web applicaton in Tomcat2:
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:1111
jcs.auxiliary.LTCP.attributes.TcpListenerPort=1111
and got following error message:

Why I always got error message: "ERROR org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPCacheManager - Failure, lateral instance will use zombie service
java.io.IOException: Socket is null, cannot connect to localhost:1110"
Many thanks,
