There are several things you can do to ensure that your KVStore is up and fully functional.
Run the ping command.
> java -jar KVHOME/lib/kvstore.jar ping -port 5000 -host node01 Pinging components of store mystore based upon topology sequence #107 mystore comprises 300 partitions on 3 Storage Nodes Datacenter:Boston [dc1] Storage Node [sn1] on node01:5000 Datacenter: Boston [dc1] Status: RUNNING Ver: 11gR2.1.0.28 Rep Node [rg1-rn1] Status:RUNNING,MASTER at sequence number:31 haPort:5011 Storage Node [sn2] on node02:5000 Datacenter: Boston [dc1] Status: RUNNING Ver: 11gR2.1.0.28 Rep Node [rg1-rn2] Status:RUNNING,REPLICA at sequence number:31 haPort:5011 Storage Node [sn3] on node03:5000 Datacenter: Boston [dc1] Status: RUNNING Ver: 11gR2.1.0.28 Rep Node [rg1-rn3] Status:RUNNING,REPLICA at sequence number:31 haPort:5011
Run the simple "hello world" example. Go to the KVHOME directory and compile the example:
javac -cp lib/kvclient.jar:examples examples/hello/*.java
Then run the example (from any directory):
java -cp KVHOME/lib/kvclient.jar:KVHOME/examples \ hello.HelloBigDataWorld \ -host <hostname> -port <hostport> -store <kvstore name>
This should write the following line to stdout:
Hello Big Data World!
Look through the Javadoc. You can access it from the
documentation index page, which can be found at
KVHOME/doc/index.html
.
If you run into installation problems or want to start over with a new store, then on every node in the system:
Stop the node using:
java -jar KVHOME/lib/kvstore.jar stop -root KVROOT
Remove the contents of the KVROOT directory:
rm -rf KVROOT
Start over with the steps described in Installation Configuration.
