System Requirements for Installing CA Spectrum

Last update May 17, 2018


Important! CA Spectrum r10.0 and higher versions only support 64-bit Operating Systems and does not support 32-bit Operating Systems.

System Configurations

The configuration tables in this section provide guidelines for running CA Spectrum at peak efficiency. You can achieve optimal system performance when all system resources are robust enough that a single resource does not limit the other resources. System resources include memory, processor speeds, and disk space.

Note: Consult your support or sales representative for more help in determining the best configuration for your network.

You cannot define all configurations and system requirements for all users because of the following complexities and variables:

  • Polling frequency
  • Device types
  • Number of devices in a network
Important! Installing OneClick on a single-CPU SpectroSERVER host system can degrade the performance of both SpectroSERVER and OneClick. To maximize the performance of both, we recommend that you install OneClick on a separate, dedicated computer. If you upgrade SpectroSERVER components, you might also need to upgrade OneClick.

System Support and Setup Considerations

Virtualization Environments

CA Spectrum supports the following virtualization environments:

  • Solaris Zones
  • VMware for Windows and Linux

    Note: For information about CA VMware guidelines, see Virtualization.

Rule of Localization Homogeneity

The Rule of Localization Homogeneity states that all components in a distributed CA Spectrum installation must run on servers that use the same operating system Locale. Think of CA Spectrum as one application running with one language, rather than as a set of distributed services potentially running different languages.

By following the Rule of Localization Homogeneity, you ensure that all access and modification of data through different communication paths use one consistent language. Otherwise, myriad languages can be stored in the CA Spectrum database. The multiple languages cause problems with such data issues as display, fonts, searching, and sorting.

We recommend that you set the Locale on the servers that run CA Spectrum processes before you install CA Spectrum. Such servers include the Location server, Processd, SpectroSERVERs, OneClick servers, clients, and the Secure Domain Manager.

Disk Striping and RAID

For optimum performance, you can run CA Spectrum on systems with multiple, ultra-wide, 10,000 RPM, SCSI disk drives that use disk striping or RAID (redundant array of independent disks) technologies.

Disk striping is a technique of spreading data over multiple disk drives. RAID is a disk drive system that uses two or more drives in combination for fault tolerance and performance improvement.

Symantec pcAnywhere

Symantec pcAnywhere™ can cause Java to lock and prevent Java applications from launching. Java applications include OneClick Console, CA Spectrum Control Panel, Model Type Editor, and Performance View. The processes start, but the GUIs do not launch. If you stop pcAnywhere, the Java-based applications launch and the GUIs display correctly.

To resolve this issue, install or upgrade to DirectX version 9.0 B, which is available at

Alternatively, you can stop the pcAnywhere Host Service before installation. After you install CA Spectrum and OneClick, you can enable the pcAnywhere Host Service again.

Antivirus Software and Data Backup

CA Spectrum does not include antivirus software. We recommend installing your preferred antivirus software to protect your networking environment.

Important! To avoid database corruption, exclude CA Spectrum installation areas and CA Spectrum files from scans by any local or remote instances of antivirus software. CA Spectrum installation areas include OneClick and Report Manager installation areas.

Exclude all CA Spectrum installation areas, including OneClick and Report Manager installation areas, from scans by data backup programs.

Swap Space Recommendations


Amount of Installed RAM 

Recommended swap space

    16- 32 GB        

      16 GB


System Type

Swap Volume Size

Dump Volume Size

Mid-range server with about 8 GB of physical memory

2 GB

4 GB

High-end server with about 16 to 128 GB of physical memory

4 GB

8-64 GB

Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7

Important! Since RH 5.x is no longer supported (from march 2017) by Red Hat, we recommend you to upgrade to RHEL 6.x or 7.x for CA Spectrum 10.1 and higher versions.

Amount of installed RAM

Recommended swap space

Recommended swap space if allowing for hibernation

> 2GB - 8GB

The same amount of RAM

2 times the amount of RAM

> 8GB - 64GB

At least 4GB

1.5 times the amount of RAM

^ Disk Drives: For optimum performance, run CA Spectrum on systems with Multi-disk RAID configurations @ 10,000 RPM or greater.

    Why do we list CABI 4.1 SP3 which is no longer a valid product, shouldn't we list JasperReport server 6.3 instead??

    Linux Support

    The following table summarizes CA Spectrum support for Linux operating systems: <<Remove CABI r4.1 SP3>> Add JasperReport Server 6.3

    Could the following be corrected - under the Linux package dependencies section - it is not "PackagesKit-gtk-module", it is "PackageKit-gtk-module".

        Just cross-checked this under a CentOS and RHEL 7 install. A correction to the name, it is "PackageKit-gtk3-module".
