Hello!

I use java thin client and put 80 port at clientConfiguration.

Do I have to change port for L4?? like 'cache.ignite.com:49100'?

I think 'cache.ignite.com' is not an Ignite server node(its L4), but thin
client recognizes it for Server Node.
I'll try to change the port but I wanna sure for use L4 possibility..

partition loss policy

[kay]

Hello, I got a question about partition loss policy for cache.

I'm not sure what is partition loss and why this policy need.

If there are 4 nodes and backups=1, 2 nodes are crashed and die.
Then, There are only 2 nodes. 
Maybe *some data *are lost<--( is this partition loss??.)  If there saved
crashed node. 

If some data are lost and I use java thin client to get data(lost one).
it will be null data return..

so I don't think there is no neccessary partition loss policy for my case..
is it right?? Am I understand exactly??

[Node 2]
TCP binary : 8081
Jetty REST  : 11214

Could you guys tell me where each port is used??

Is it necessary ports? 
Do I need 5 ports each time add a new node all of different port?
if it is true, how can i set TCP binary port(8080) & Jetty REST(11213) at

Re: remote ignite server and L4(for loadbalacing) with java thin client

[kay]

Hello, Thank you so much!.

I have 1 more question.

I use IgniteClient API in my application.(singleton)
when i start my application I regist IgniteClient bean using SpringFramework
and declare ClientConfiguration  address like  

ClientConfiguration cfg = new
ClientConfiguration().setAddresses("34.1.21.122:12800",
"34.1.21.122:12800");

 Is there any way to add new ClientConfiguration address without my
application restart??
I'm considering using L4 between my application and ignite server node.. but
also L4 should be restart.

Is it possible to auto scale out java client thin level??

Re: remote ignite server and L4(for loadbalacing) with java thin client

[kay]

Hello, I'm waiting for reply :)

I use java thin clien.

1. Can I use java thin client with 'Affinity Collocation'?
2. Is there any information about 'partition awareness' ? like, example
link.
3. Ignite thin client on startup select's random server to connect available
address.
This selection(connect to server node) is not going to be change before
server node is shut down?? or my application restart?
I mean if I have only one Ignite thin client Object( like singleton ) in my
application.
Is it only use one server node?


Thank you so much

Re: remote ignite server and L4(for loadbalacing) with java thin client

[kay]

Hi, Could you share about "partition awareness" detail information? 
like, example link.

And  you said Ignite thin client on startup select's random server to
connect available address.
This selection(connect to server node) is not going to be change before
server node is shut down?? or my application restart? 

I mean if I have only one Ignite thin client Object( like singleton ) in my
application. 
Is it only use one server node?

I use java thin client now 



Thank you

Re: TcpDiscoverySharedFsIpFinder with different machine..

[kay]

yes, I  wrote a path and it worked at same machine(it means same IP).
My question is how can i set *different machine*(different IP,).

For example)
I have 4 node 

--> machine 1 IP list
41.1.122.122:12200-> a
41.1.122.122:12202-> b


- machine 2 IP list
41.1.122.123:12200-> c
41.1.122.123:12202-> d


(a,b) cluster is working 
(c,d) cluster is also working.

i want to cluster all 4 nodes(a,b,c,d) and is there any way to use
TcpDiscoverySharedFsIpFinder configuration?

ignite webSession clustering about session timeout

[kay]

Hello,  I'd like to use ignite websession cluster ..
but, I'm wondering about ignite session timeout algorithm.
I figured out every websession data make with expiry policy in source code.
Is it only dependency of ignite cache expiry policy??

What happen if I made a class implements HttpSessionListener interface?
Is it going to be method working sessionDestroyed, sessionCreated??
Please help me..

Thank you.

Re: remote ignite server and L4(for loadbalacing) with java thin client

[kay]

Hi,

I'm using Apache Webserver for loadbalancer.

I got this access log at binding port.




- myIp(xx.xx.xx.xxx) [06/Apr/2020:09:00:50 +0900] 13000 "-" 408 - 12 0 - -




I think it was a timeout.

Here is my httpd.conf set.





 BalancerMember "http://IP:PORT; loadfactor=1 hcpasses=3  hcfails=3 
hcmethod=GET  hcinterval=5
 BalancerMember "http://IP:PORT; loadfactor=1 hcpasses=3  hcfails=3 
hcmethod=GET  hcinterval=5 
 ProxySet  lbmethod=byrequests
 


 ProxyRequestsOff
ProxyPreserveHost   On

  ProxyPass   "/"  "balancer://cache-cluster/"
 ProxyPassReverse"/"  "balancer://cache-cluster/"
 







and this is a stacktrace for connection

remote ignite server and L4(for loadbalacing) with java thin client

[kay]

Hello, 
I have two nodes in each remote server and using java thin client for
put/get/remove caching at my application.
I'd like to put L4 or webserver between application server and Ignite Server
for loadbalancing.

there are informations of ports for my description and if IP is all same.

1) node1 
  - client connect port 12000
  - server port 12001

2) node2
  - client connect port 12002
  - server port 12003

3) L4(Webserver)
  - port number : 13000

I used before in my source
ClientConfiguration cfg = new ClientConfiguration().setAddresses(IP:12000,
IP:12002);

I already chage like this 

ClientConfiguration cfg = new ClientConfiguration().setAddresses(IP:13000);

but it was got a ClientConnectionException: Ignite cluster is unavailable
[sock=Socket[addr[. and so on...

is it possible to use like this?? or Is there another way??? 

Thank you

Ignite Web Session Clustering with standalone node

[kay]

I'd like use web session clustering in my application.

I checked a page
https://apacheignite-mix.readme.io/docs/web-session-clustering and There is
no way to set standalone ignite nodes.. only like this ...



   IgniteConfigurationFilePath
   config/default-config.xml 

how to set server ip:port at web.xml file?? or is there another way to
connect to ignite server??

Thank you
