System Requirements for Installing CA Spectrum
CA Spectrum r10.3 only supports 64-bit operating systems and does not support 32-bit operating systems.
The configuration information in this section provides guidelines for running
CA Spectrumat peak efficiency. You can achieve optimal system performance when all system resources are robust enough so that a single resource does not limit the other resources. System resources include memory, processor speeds, and disk space.
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
Installing OneClick on a single-CPU
SpectroSERVERhost system can degrade the performance of both
SpectroSERVERand OneClick. To maximize the performance of both, we recommend that you install OneClick on a separate, dedicated computer. If you upgrade
SpectroSERVERcomponents, you might also need to upgrade OneClick.
System Support and Setup Considerations
CA Spectrumsupports the following virtualization environments for Windows and Linux
For information about CA VMware guidelines, see Virtualization.
Rule of Localization Homogeneity
Rule of Localization Homogeneitystates that all components in a distributed
CA Spectruminstallation must run on servers that use the same operating system Locale. Think of
CA Spectrumas 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 Spectrumdatabase. 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 Spectrumprocesses 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 Spectrumon 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™ can cause Java to lock and prevent Java applications from launching. Java applications include OneClick Console,
CA SpectrumControl 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 http://support.microsoft.com.
Alternatively, you can stop the PCAnywhere Host Service before installation. After you install
CA Spectrumand OneClick, you can enable the PCAnywhere Host Service again.
Antivirus Software and Data Backup
CA Spectrumdoes not include antivirus software. We recommend installing your preferred antivirus software to protect your networking environment.
To avoid database corruption, exclude
CA Spectruminstallation areas and
CA Spectrumfiles from scans by any local or remote instances of antivirus software.
CA Spectruminstallation areas include OneClick and Report Manager installation areas.
CA Spectruminstallation areas, including OneClick and Report Manager installation areas, from scans by data backup programs.
Swap Space Recommendations
Amount of Installed RAM
Recommended swap space
Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7
From CA Spectrum 10.2.2 and above, support for RHEL 5.x is discontinued. We recommend you to upgrade to RHEL 6.x or 7.x.
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 Spectrumon systems with Multi-disk RAID configurations @ 10,000 RPM or greater.
