Resource usage on the Operations Center computer
The number of administrators who are logged in to the Operations Center affects resource usage on the computer where the Operations Center runs.
Resource usage for each logged-in administrator
- Running the Operations Center uses about 3% of a processor core (based on an Intel X7550 2.00 GHz or equivalent processor).
- Each administrator who is logged in to the Operations Center uses 2% - 3% of a processor core on the computer where the Operations Center runs. This usage level assumes that each administrator completes about 40 tasks per hour.
- The Operations Center might have 8 - 10 administrators who
are logged in and completing tasks at the same time. A task might be one of the following
activities:
- Opening and viewing a page, window, or wizard in the interface, for example, a storage pool Properties page, a server Quick Look window, an Alert Details window, or the Add Client wizard.
- Configuring settings on the Settings page
- Issuing a command from the Operations Center command line
Memory for the JVM heap size
The Operations Center requires at least 128 MB of memory for the maximum Oracle Java™ virtual machine (JVM) heap size for up to eight concurrently logged-in administrators. This memory requirement assumes that each administrator completes about 40 tasks per hour within the user interface. The JVM uses a maximum of 1 GB, or 25% of the physical memory of the system (with systems that have more than 192 MB of memory). The heap size starts at a smaller amount but can increase up to the maximum.
- installation_dir/ui/Liberty/usr/servers/guiServer/
- installation_dir\ui\Liberty\usr\servers\guiServer\
If the jvm.options file is not in the directory, and you must adjust the memory, create the file in the directory.
