Change the Linux heap size

MVS installs a default heap size, which includes a minimum setting of 64 MB and a maximum setting of 512 MB for services and applications.

About this task

  • A minimum setting of 64 MB and a maximum setting of 512 MB should be sufficient settings for most environments.
  • The heap size should not affect current computer settings or bandwidth, but rather it might improve scalability.

Procedure

  1. Open the tlx.xml configuration file from the /usr/local/RocketSoftware/mvs/server/ directory and edit the ServiceArguments:
    "\-Xms64M" -a "\-Xmx512M"
  2. Save the file.
