Hardware and Memory Specifications


The Hardware and Memory Specifications overview summarizes memory specifications for web components of uAchieve.

Two aspects include the following: 

  1. Hardware:
    1. Ensure your machine has sufficient memory
    2. The virtual machine the uAchieve applications will be installed on (e.g., Tomcat, Weblogic) needs to have at least 2 GB of RAM
  2. Software
    1. Configure the Java memory parameters (HEAP, PermGen) to use the RAM
    2. See below:

Total Argument Parameters for all uAchieve Applications

If installing all components of uAchieve, set the parameters to the sum of each application. These values are summarized for you below:

 

HEAP Space 1

(GB)

PermGen Space 2

(MB)

uAchieve 1.3 240

1 The HEAP Space requirement for all uAchieve applications is determined by adding each of the four components (below) together and rounding up, if necessary.

2 The PermGen Space requirement for the entire Suite is determined by rounding each of the four components (below) up to a value of 60.


 

Individual Breakdown by Component:

If installing individual components, set the parameters according to the values below:

Dashboard

Be sure to start the application server with the following minimum memory settings: 

 

HEAP Space

(MB)

PermGen Space

(MB)

Dashboard 320 32
Sample Java Command Line Arg -Xmx320m -XX:MaxPermSize=32M

 

Self-Service

Be sure to start the application server with the following minimum memory settings: 

 

 

HEAP Space

(MB)

 

 

PermGen Space

(MB)

 

u.achieve Self-Service 184 56
Sample Java Command Line Arg -Xmx184m -XX:MaxPermSize=56M

 

uAchieve Planner (formerly u.direct)

Be sure to start the application server with the following minimum memory settings:

 

 

HEAP Space

(MB)

 

 

PermGen Space

(MB)

 

Planner 712 56
Sample Java Command Line Arg -Xmx712m -XX:MaxPermSize=56M

 

Schedule Builder

Be sure to start the application server with the following minimum memory settings:

 

 

HEAP Space

(MB)

 

 

PermGen Space

(MB)

 

Schedule Builder 72 48
Sample Java Command Line Arg -Xmx72m -XX:MaxPermSize=48M

 

Schedule Builder creates a log file upon startup. If you experience deployment issues with the application not starting, accurate error messages will help troubleshoot these.
