Application server system requirements

This topic describes the system requirements for the TrueSight Network Automation application server

Note

If you would like Network Automation to support any particular version of operating system or database, log an IDEA on BMC Communities .

The application server is bundled with a PostgreSQL database, TFTP server (for Microsoft Windows), syslogd server, and the following third-party software:

Note

  • Network Automation version 20.02 does not support installation on Windows Server 2012, Windows Server 2012 R2, and Windows Server 2016 on the Resilient File System (ReFS).
  • Network Automation version 20.02 does not support installation on an IPv6 system where the local host name does not get resolved via Domain Name System (DNS). That is, the  nslookup command on the local host name must succeed if the product needs to use an IPv6 stack.

Database support


The following databases are supported for use with the application server:

  • Oracle Database 11g release 2 (external database encryption)
  • Microsoft SQL Server 2017 AlwaysOn Clustering
  • Microsoft SQL Server 2017 Active-Passive Mode Clustering
  • Microsoft SQL Server 2016 (support for encrypted connections)
  • Microsoft SQL Server 2014 (support for encrypted connections)
  • Microsoft SQL Server 2012 (support for encrypted connections)
  • PostgreSQL 10.22
  • PostgreSQL 9.6.4
  • PostgreSQL 9.5.5

  • PostgreSQL 9.5.3

    Note

    1. The supported version of 12c is 12.1.0.2 with pluggable database (PDB).

    2. When you choose the embedded database option, Network Automation version 20.02 uses the PostgreSQL version 10.2.

Warning

Network Automation does not support database compression. Therefore, you must disable database compression prior to installing or upgrading Network Automation.

Hardware requirements

The application server specifications in the following table are based on the number of managed devices. These specifications are for a live production environment.

24 GB

The application server and database can run on the same host computer or different host computers or virtual machines (VMs).


Note

When uploading OS images larger than 300 MB to Network Automation, the system running PostgreSQL must have enough RAM when Network Automation writes large OS image files to the database. BMC recommends that the system running PostrgeSQL have RAM greater than three times your maximum OS image file size.

If you are running the Network Automation application server and PostgreSQL on the same computer, make sure you have sufficient cumulative RAM.

In addition, your Java heap must be configured to process large files. BMC recommends that you set your maximum java heap size (-Xmx <size>) to three times your maximum OS image file size. See Performance-tuning.

Disk space requirements

Note

The application server installation procedure requires approximately 1.2 GB of free disk storage. For more information about the installation procedure, see Installing.

The following table lists the disk space requirements of these components. The requirements are separate and independent, whether the components run on the same host or different hosts.

Disk space requirements

Total requirement (configuration files, log files, and so on)

5 GB

Database server

General data
Configuration and image data

Note

45 KB per configuration * 90 days * 1 configuration per day = 4 MB for configurations
30 MB per image / 30 devices per image = 1 MB for images
25 KB per transcript * 1 job per day * 90 days = 2.25 MB for transcripts
25 KB per transcript * 20 span actions = 0.5 MB for device status
(where 90 days is the default job/configuration purge criteria)

Per-device sizing is greatly affected by the number of changes made per day (more changes result in more configurations and more transcripts), the type of image the device is running (many images can be over 100 MB in size), the use of tunneled mode for snapshots (where the configurations are also embedded in every transcript), and the purge settings for both configurations and jobs.

User account privileges

The Network Automation Oracle or Microsoft SQL Server user account must be granted the following privileges:

  • Create/alter/drop tables/indexes/constraints
  • Insert/update/delete rows
