Host Machine Requirements

Host Machine Requirements

This topic describes the host machine requirements for Pivotal GemFire.

Each machine that will run Pivotal GemFire must meet the following requirements:
  • A supported Java SE installation. See Pivotal GemFire Supported Configurations.
  • Adequate per-user quota of file handles (ulimit for Solaris and Linux).
  • TCP/IP.
  • System clock set to the correct time and a time synchronization service such as Network Time Protocol (NTP). Correct time stamps allow you to do the following activities:
    • Produce logs that are useful for troubleshooting. Synchronized time stamps ensure that log messages from different hosts can be merged to reproduce a chronological history of a distributed run.
    • Aggregate product-level and application-level time statistics. 
    • Accurately monitor your GemFire system with scripts and other tools that read the system statistics and log files.
  • Hostname and host files that are properly configured for the machine. Hostname and host file configuration can affect gfsh and Pulse functionality. On Linux and Unix hosts, see the system manpages for more information on setting hostname and hosts.
Note: For troubleshooting, you must run a time synchronization service on all hosts. Synchronized time stamps allow you to merge log messages from different hosts, for an accurate chronological history of a distributed run.
