- To ssh into specific containers, run following commands
- e.g. ssh into server2.
docker exec -it server2 /bin/bash
- To execute function on the server, do following
-
Open the project in IntelliJ
-
Run com.demobank.gemfire.functions.DataSeeder
This will setup a set of transactions for two different dates and accounts. This makes sure that data is available on both the servers.
-
Run com.demobank.gemfire.functions.RemoteTransactionSearchTest
At this point the test just runs a function to get all the transactions for given accounts and dates.
-
- ssh into server2 and install and use tc to put network latency of 16 seconds.
docker exec -it server2 /bin/bashbash-4.4# apk add iproute2bash-4.4# tc qdisc add dev eth0 root netem delay 16000msbash-4.4# tc -s qdisc
- Wait for some time. Monitor server2 and locator1 logs. Locator will not receive heart beat
- and will remove server2 from view, server2 will shutdown but will have reconnect thread running.
- Now remove network latency by following command
bash-4.4# tc qdisc del dev eth0 root netem
- Observe network queue clearing up.
bash-4.4# tc -s qdisc
- Observe server2 logs. It reconnects to cluster and gets all the new configuration from locator including deployed jars
