Data Mart > MPP > Machine Deployment > How to Deploy the Standalone Version of Data Mart System

Make a rough estimation: suppose that standalone is a 2-route 10-core CPU, and PC Server of 32G memory, it can support 500G data, about 300 million pieces of data. Due to the different data features of various industries, the estimation factor should be adjusted accordingly.

Select the hardware of device, according to the installation manual, install Yonghong data mart software into the operation system. Choose the installation procedures of local data mart during installation. If the parameter setting is wrong during installation, open the relevant files under bihome to revise the parameter.

Here are some examples of required parameter settings.Configure the metadata file address of naming node and child node,directory where child nodes store physical files and the local IP.

dc.fs.naming.paths=c\:/bihome/cloud/qry_naming.m

dc.fs.sub.path=c\:/bihome/cloud/qry_sub.m

dc.fs.physical.path=c\:/bihome/cloud

dc.io.ip=192.168.1.99

Two more parameters should be given special considerations. The revision can be made manually in the local configuration files.

mem.serial.mem=10240

mem.proc.count=12

This is the configuration of the current machine during installation. 12 threads can be scheduled. The allocated memory for storing data is 10G.

In addition, the memory size allocated to JVM should be considered during installation. Under the current environment, if there is no other service taking up resources, 31G could be allocated to it. Input 31744 during installation. The memory size of JVM must be larger than the memory block of loaded data, at least larger than 700M.

After the installation, please confirm that access permission is given to the installation package. If it is under linux,it's best to start the program as a superuser.
