Hi all: As a new people for JCS, I tried a Lateral TCP Cache and Lateral UDP Discovery. And I have got a very interesting result.
This is the testing environment: I created a server and a client (on the same machine). Server provides the function for user to create objects through the command line. The object will be saved to the disk (block disk cache) and also be distributed to the client by using the TCP lateral cache. The client is running on jre1.6.0_05. The server will be running on different versions of JRE (jre1.6.0_02, jre1.6.0_03, and jre1.6.0_05). I tried the Lateral TCP Cache first. No problem at all! The objects created from the server will be automatically cached to the client. Then I tried the Lateral UDP Discovery. If the server is running on jre1.6.0_03 or jre1.6.0_05, there is no problem. But if the server is running on jre1.6.0_02, the objects can not be distributed to the client. The logging results are below: 14-May-2008 14:47:38 org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPSender init INFO: Attempting connection to [UKDTLIY.UK.NDS.COM] 14-May-2008 14:47:43 org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPService <init> SEVERE: Could not create sender to [172.20.110.79:8880] -- Socket is null, cannot connect to 172.20.110.79:8880 14-May-2008 14:47:43 org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPCacheManager fixService SEVERE: Can't fix Socket is null, cannot connect to 172.20.110.79:8880 14-May-2008 14:47:43 org.apache.jcs.auxiliary.lateral.LateralCacheRestore canFix SEVERE: Can't fix Can't fix Socket is null, cannot connect to 172.20.110.79:8880 14-May-2008 14:48:03 org.apache.jcs.auxiliary.lateral.LateralCacheMonitor run INFO: LateralCacheManager.instances.size() = 1 14-May-2008 14:48:03 org.apache.jcs.auxiliary.lateral.LateralCacheMonitor run INFO: 1- mgr.getCaches().size() = 2 14-May-2008 14:48:03 org.apache.jcs.auxiliary.lateral.LateralCacheMonitor run INFO: found LateralCacheNoWait in error, LateralCacheNoWait Status = 3 cache = [ LateralCache Cache Name [DogCache] cattr = [172.20.110.79:8880:8888]] It looks that the server cannot build the TCP connection. ********************************************************************************************************* This e-mail is confidential, the property of NDS Ltd and intended for the addressee only.
