Core Deployment: System Requirements

FlexNet Manager Suite 2022 R1 (On-Premises)

The following details apply to the FlexNet inventory core components when you use your preferred third-party deployment processes to install them on a target Windows device.

Supported platforms

The FlexNet inventory core components operate on the following platforms (inventory targets):
Microsoft Windows UNIX-like platforms
  • Windows Server 2003 SP1 and SP2, 2008 R2 x64, 2012, 2012 R2, 2012 R2 SP1, 2016, 2019, 2022
  • Windows Server Core 2008, 2008 R2 x64, 2012, 2012 R2
  • Windows Server Standard (previously known as Windows Server Core) 2016, 2019
  • Windows Vista x64, 7 x64, 8 x64, 10 x64
  • Windows Vista, 7, 8, 10, 11.
  • AIX 7.1 LPARs, 7.2
  • Amazon Linux 2
  • CentOS (x86, 32-bit and 64-bit): 6-7.5; (x86 64-bit only): 7.6-7.9 (lower versions); 8.0-8.4 (higher versions)
  • Debian Linux 7–11 (x86 32-bit and 64-bit)
    Note: For Debian Linux 9.4, 9.5 and 10 (both 32-bit and 64-bit), minimal installations of the OS core omit the ifconfig command. This prevents collection of the IP address and MAC address in inventory. The root user can use the following command to restore this functionality:
         apt-get install net-tools  -y
  • Fedora Linux 25-30 (x86, 32-bit and 64-bit); 27-34 (x86 64-bit only)
  • HP-UX 11i v3, vPars/nPars
  • macOS 10.6–12
    Note: To run on an Apple M1 processor ("Apple silicon"), the FlexNet inventory agent requires that Rosetta 2 is installed and running. This is Apple's solution for transitioning most Intel-based applications to run on Apple silicon. There are two possible command formats for installing Rosetta 2:
    • Interactive installation that asks for agreement to the Rosetta 2 license:
    • Non-interactive installation:
          --install-rosetta --agree-to-license
  • OpenSuSE Leap 42.2, 42.3 (x86, 32-bit and 64-bit); 15-15.3 (x86 64-bit only)
  • Oracle Linux 4.5–6.10 (x86, 32-bit and 64-bit); 7.0-8.4 (x86 64-bit only)
  • Photon OS 3.0-4.0
  • Red Hat Enterprise Linux (RHEL) (x86, 32-bit and 64-bit) 5.0–6.10; (x86 64-bit only) 7.0-7.9 (lower versions); 8.0-8.4 (higher versions)
  • Red Hat Linux 8–9 (x86 only)
  • Solaris 8–11.4 (SPARC), Zones for versions 10–11
  • Solaris 9–11.4 (x86), Zones for versions 10–11
  • SuSE Linux Enterprise Server 11 (x86, 32-bit and 64-bit); 12 SP3, 12 SP4, 12 SP5, 15, 15 SP1, 15.2, 15.3 (x86 64-bit only)
  • Ubuntu 12–17.04 (x86, 32-bit and 64-bit); 17.10-21.04 (x86 64-bit only).

Disk space requirements

On target Windows inventory devices in the Core deployment case, the following are disk space requirements:
  • Where the target device is a typical workstation, in the order of 6MB
  • For an Oracle server, in the order of 9MB.
The following log file is available on the target inventory device in the Core deployment case:
  • tracker.log — Generated by the inventory component, ndtrack

Memory requirements

On target inventory devices, the memory requirements are:

  • Minimum RAM: 512 MB
  • Recommended RAM: 2 GB
In general, through a cycle of inventory gathering and upload, the memory demand is in the order of 5-30 MB.

Communications protocols and ports

When the FlexNet inventory core components execute on the target device (in the Core deployment case), the only ports required are the standard ports for communication with the inventory beacon:
  • From FlexNet inventory core components on target device, inbound on the inventory beacon — File upload using HTTP protocol: port 80
  • From FlexNet inventory core components on target device, inbound on the inventory beacon — File upload using HTTPS protocol: port 443

Supported packages to inventory

FlexNet inventory can include data from most package technologies supported by the operating systems, and some additional third-party packaging technologies:
Platform Supported package technologies

All platforms

InstallAnywhere (IA), InstallShield Multiplatform (ISMP), BEA/Oracle Installer (BEA), Oracle Universal Installer (OUI), IBM Installation Manager (IIM)




Software Distributor SD-UX Package


RPM (Red Hat, CentOS, Oracle, SuSE, Fedora, etc), DPKG (Debian, Ubuntu).

Mac OS X

Mac Application Bundle, Mac Package Bundle


Sys V Package (pkg), IPS


MSI, Add/Remove Programs Registry Key

However, FlexNet inventory cannot collect data from some of the less common or newer operating system technologies and many third-party technologies. Some known examples include:
  • All platforms — IBM InstallStream, IBM Tivoli Netcool Installer
  • Mac OS X — Mac flat package.
