1. Create 2VMs and install RHEL
2. Add static IP ( Private IP in our
case) to these 2VMs
3. Assign hostname to 2VMs in
/etc/sysconfig/network file
4. Map 2VMs static IP and Hostname
details in the /etc/hosts file.
5. Disable the firewall (iptables) /etc/sysconfig/iptables

Download Oracle java
jdk rpm and run, this case have installed the latest version of JAVA 8
available during the time testing.
rpm –Uvh jdk-8u73-linux-x64.rpm
Check Java installed
and add JAVA_HOME and bin path into environment variables.
Install Maven
apache-maven-3.1.1-bin.tar.gz
sudo tar xzf apache-maven-*-bin.tar.gz -C /usr/local
cd /usr/local
sudo ln -s apache-maven-* maven
sudo vi /etc/profile.d/maven.sh
Add the following to maven.sh
export M2_HOME=/usr/local/maven
export PATH=${M2_HOME}/bin:${PATH}
Reload bash and test mvn

Install
YCSB and Setup
Download the latest version of YCSB with
MongoDB binder only, no need to download whole YCSB package with all DB
binders.
Extract the tar file and
place in the home directory (or any place where you maintain the software
repository)
curl -O --location
https://github.com/brianfrankcooper/YCSB/releases/download/0.7.0/ycsb-0.7.0.tar.gz
tar xfvz ycsb-0.7.0.tar.gz
cd ycsb-0.7.0
Try below commands if it runs successfully then you’re good
to proceed if not then necessary python argparse package have to be installed.
(RHEL 6 deprecated this this package)
Tar –zxvf argparse-1.4.0.tar.gz
Cd argparse-1.4.0
Python setup.py install
Test YCSB runs successfully
$ ./bin/ycsb shell basic
> help
Commands:
read key [field1 field2
...] - Read a record
scan key recordcount
[field1 field2 ...] - Scan starting at key
insert key name1=value1
[name2=value2 ...] - Insert a new record
update key name1=value1
[name2=value2 ...] - Update a record
delete key - Delete a
record
table [tablename] - Get
or [set] the name of the table
quit - Quit
Run YCSB on
the MongoDB cluster
Start mongd instance on all the
nodes of Recplicaset.
Data Load command
./bin/ycsb load mongodb-async -s -P workloads/workloada -p
mongodb.url=mongodb://localhost:27017/ycsb?w=0
To run with the synchronous driver from MongoDB:
./bin/ycsb load mongodb -s -P workloads/workloada -p
mongodb.url=mongodb://localhost:27017/ycsb?w=0
Load more data using more threads
./bin/ycsb load mongodb-async -s -P workloads/workloada -p recordcount=10000000
-threads 16 mongodb.url=mongodb://localhost:27017/ycsb?w=0
·
‘load‘ flag indicates that this is a load run.
·
‘s‘ flag prints status at 10 sec intervals
·
‘recordcount‘ is set to 10 million.
·
‘threads‘ sets the number of client threads to 16.
Run async driver mongodb with operation count same as data load row
count and thread 2
./bin/ycsb load mongodb -s -P workloads/workloada -p
mongodb.url=mongodb://localhost:27017/ycsb?w=0 -p operationcount=10000000
-threads 2
Running the Tests on different workloads.
·
Workload A: Update heavy workload: 50/50% Mix of
Reads/Writes
·
Workload B: Read mostly workload: 95/5% Mix of
Reads/Writes
·
Workload C: Read only: 100% reads
·
Workload D: Read latest workload: More traffic
on recent inserts
·
Workload E: Short ranges: Short range based queries
·
Workload F: Read-modify-write: Read, modify and
update existing records
Loading 94Gb data
Record count 8000000
[root@ycsb1 ycsb]# ./bin/ycsb load mongodb-async -s -P
