Automatically Tune MashZone Memory and Cache Configuration

This uses a simple script to automatically update memory and cache configuration based on preset sizes. These preset values, however, do not take any memory requirements for MashZone NextGen or MashZone NextGen In-Memory Stores into account and thus may not be suitable in some circumstances.

1. Determine which present configuration you want to use.

Preset memory configuration is defined by three sizes: s = small, m = medium and l = large. These presets are configured based on the following assumptions:

Preset Option	Heap	Core Threadsize	Maximum Threadsize	Internal Caches
S: a small application on a host with: 64 bit 2 Cores 4G of memory	1G	4	4	Base = 125M Top = 100M Debug =25M
M: a medium application on a host with: 64 bit 4 Cores 16G of memory	8G	8	12	Base = 1G Top = 800M Debug =200M
L: a large application on a host with: 64 bit 8 Cores 64G of memory	16G	16	24	Base = 2G Top = 1.6G Debug = 400M

2. Open a command or terminal window and move to the MashZoneNG-install/mashzone/tool/runtool folder.

3. Enter the appropriate command shown below based on your operating system:

For Windows, enter upgradetool.bat -system preset-size

Using the size option you determined in step 1.

For Linux, OS/X or UNIX, enter upgradetool.bat -system preset-size

Using the size option you determined in step 1.

4. If needed, manually increase the Java heap allocation to accommodate both MashZone NextGen and the Integrated MashZone Server. See Memory Configuration for the MashZone NextGen Server for instructions.
