ehcache port issue

[lakshmi maha]

Hi Team,
WAS Liberty Version: com.ibm.websphere.liberty.v85_8.5.200004.20200401_1714

we have a usecase for Resetting credentials.Its a two step process:
1).User Verification - If user is verified, creating a sessionID and storing userProfile details in cache for next step.
2).Reset credts - checks created session Id and fetches userProfile to reset password.

To acheive this usecase our team tried to implement EHCache solution

We are facing the following error:

Tried below steps:
===============
a)added ehcache.xml under server instance directory
b)FabCaching-0.0.1-SNAPSHOT.jar placed under shared resources

c)added <feature>ejbRemote-3.2</feature> in server.xml and receiving the following error message.

Connection refused is an indicator that either the wrong port number/address is being used, or the service on the other side is not running, or a firewall is blocking the connection.

Hi John,

Please find the below configuration which we used in ehcache.xml file as per manual configuration.

we have used 40001 which is allowed on the network 

we have followed this doc to configure xml however the port is not listening in the server and getting the above error.

<cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual, rmiUrls=//hostname:40001/UserProfileCache" />
<cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=hostname, port=40001,SocketTimeoutMillis=3000" />

<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=hostname, port=40001,
socketTimeoutMillis=2000"/>  

kindly help in fixing this issue.(hostname we have used fqdn of server)
