CM Server hardware and software requirements

For the latest WebSphere® Application Server requirements and information about supported configurations, search http://www.ibm.com/software/webservers/appserv/. For recommendations and best practices for configuring WebSphere Application Server see http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/topic/com.ibm.websphere.base.doc/info/aes/ae/tprf_tunehdwcap.html.

Because each WebSphere Application Server instance requires 512 MB of memory, you may need to increase memory to improve performance and prevent the system from paging memory to the disk. Allow a minimum of 256 MB of memory for each processor and 512 MB per application server, where an application server is the same as a WebSphere Application Server profile. Adjust the available memory when the system pages and the processor utilization is low because of the paging. The memory access speed might depend on the number and placement of the memory modules and some applications might require more memory. To increase the allocated memory, see Increasing the maximum JVM heap size.

Specific patches must be applied for Solaris 10, for example, Patch 120664-01. Download this and other fixes from Sun.

If you are running Red Hat Enterprise Linux® 4, go to IBM® Support and search for the article "Preparing RHEL 4 for the installation of WebSphere Application Server products" before installing your product. Use the keywords RHEL 4 and WebSphere Application Server in your search.
