ActiveGate hardware and system requirements

This topic explains the hardware and operating system requirements for installing ActiveGate.

Synthetic-enabled ActiveGates support a subset of operating systems. See System and hardware requirements for synthetic-enabled ActiveGates.

Hardware requirements

You need a machine dedicated to ActiveGate that has:

  • 2 GB free disk space
  • 2 GB RAM (4 GB recommended)
  • 1 dual core processor

For large environments, you may need to use a machine with additional CPU and memory.

We recommend

For optimal performance, we strongly recommend that you install and run the ActiveGate on a dedicated system.

The 2 GB free disk space includes minimum space for specific log directories:

Linux Default Path Windows Default Path Description ActiveGate Minimum disk space

Synthetic-enabled ActiveGates are more demanding in terms of hardware requirements. See System and hardware requirements for synthetic-enabled ActiveGates.

System requirements

Linux requirements

  • Your operating system must handle at least 500,000 open files for the dtuserag user.
    To view the system limit, execute the following command:

    [user@host]# cat /proc/sys/fs/file-max
    

    Also, it may be that you've checked out too many open files in Linux.

  • Your operating system must have at least 20,000 processes available to the dtuserag user.
    To view the system limit, execute the following command:

    [user@host]# cat /proc/sys/kernel/pid_max
    
  • The ActiveGate Linux installer doesn't support ACL (Access Control List). ACL rules may prohibit access to installer-created directories and files, making the ActiveGate fail to start. If you use the ACL, rules related to the installation directories defined in the following parameters should be disabled:

    INSTALL=  
    CONFIG=  
    LOG=  
    TEMP=  
    PACKAGES_DIR=
