1.4.3 Setting Java heap memory sizes

Open the usrconf.cfg file and then set the minimum and maximum sizes of Java heap memory, according to the procedure below.

Prerequisites

To perform this task, the system administrator logs in as the built-in Administrator user to the machine on which JP1/DH - Server is installed.

Procedure

  1. Use a text editor to open the usrconf.cfg file.

    The usrconf.cfg file is stored in the following location:

    installation-folder\misc\CC\server\usrconf\ejb\jp1dh

  2. Set Java heap memory sizes.

    #------ JP1/DH - Server ---------
    add.jvm.arg=-Xmsminimum-Java-heap-memory-size#m
    add.jvm.arg=-Xmxmaximum-Java-heap-memory-size#m
    #

    Specify the memory sizes in MB.

    Specify 1,024 MB or more as the maximum size.

    We recommend that you specify the same value for the minimum and maximum sizes.

    Tip

    Set the Java heap memory sizes by considering the transmission speed and the size of the files to be sent.

    Monitor the usage of Java heap memory during operation and, if necessary, revise the size of Java heap memory.

Postrequisites

In the usrconf.properties file, set the maximum number of web clients that can connect to JP1/DH - Server and the number of web client requests that JP1/DH - Server can process concurrently.
