Java VM Memory Allocation

Products

• CA API Gateway

Issue/Introduction

In the API Gateway software, the following is described in the document:

-------------------------------------------------------------

Java VM Memory Allocation: Enter the amount of memory to allocate to the Java Virtual Machine or press [Enter] to keep the existing setting. You must allocate at least 256MB RAM.

-------------------------------------------------------------

However, it seems that value(256MB) is small.

 

What is the value which it is suitable for?

Environment

All supported versions of the API Gateway

Resolution

Support does not have any recommendation on a particular value to set for the Java VM. This value is dependent on a customer's unique environment resources. However, half of the computer's RAM is assigned to the Java VM in the gateway appliance by default.

It may become a standard.

Also, required memory is 4GB(8 GB or above recommended) for software gateways so the allotment (Java VM ) should be 2 GB or above recommended.
